@@ScannerDanner that's what you get when you're a problem solver. I work at a Ford dealership and have 26 years in the field. My phone rings off the hook from people needing help. I always try to pay it forward and help because without a lot of people's help I wouldn't be where I am today but sometimes it becomes overwhelming. It's a double edged sword but the good Lord will never give us more than we can handle.

@ironmike742 3 года назад

@@ScannerDanner also when I am unsure of the voltage reading on a window circuit since I have the master window switch right there in my hand I'll test a working circuit from another window. Testing a known good one is something you teach and preach all the time. I have learned alot from you sir. We are a dying breed. A high percentage of TECHNICIANS in the field are parts changers. Keep up the good work and just know that you are appreciated.

@KingBaconMonger 6 месяцев назад

Dang!! I was trying to figure out on a 2013 CRV: Master window switch? Passenger window switch? Motor? Regulator? I did what you said, I yanked the button on the master switch up and down, nothing, did it again, did it again, mashed it down - THE WINDOW MOVED. It's something with the master window switch. I can replace that, no problem. YOU ARE A GENIUS! Thank you, ScannerDanner!

@joeandgod1 7 лет назад

I've used the power probe, the load pro, etc... After everything, nothing beats the simplicity and efficiency of the mighty "TEST LIGHT".

@ScannerDanner 7 лет назад

agree, the test light would have been my tool of choice had it not been for the fact that I needed to manually get that window up.

@AGuysGarage 7 лет назад

Couldn't you use a DMM and just leave everything hooked up one way? When it reverses it will just read negative voltage. Easy peezy. Unless i am missing something. /shrug, love my fluke dmm with super sharp spear you in the eyeball probes

@joeandgod1 7 лет назад

I think that's another way of doing it. The only problem with the volt meter is that it doesn't "load" the circuit like the test light does. So the test light checks for ground and power and loads the circuit at the same time.

@AGuysGarage 7 лет назад

keep the motor in circuit and it supplies the load. meter just tells you if there is Voltage in both directions. Sort of a quick and dirty test. If it goes down, u get 12V so up without changing anything should be -12v because the grounds swap. if it remains 0 the motor is good because it went down, only thing left is switch / solder on the switch board. or a broken wire for up. or the module itself /shrug to each their own. once one gets the feel for it, it is shocking what you can find out just with a simple diode check setting. "use it as a short detector" I have been in electronics repair for a very long time, i guess i am just really comfy with the DMM plus it is relatively cheap compared to fancy stuff. the window circuit on my pathfinder is a bit strange, when you close the switch it grounds on a different module entirely. pretty simple really, hit the button, completes circuit and window moves. used it to install my "momentary switch 2 wire door popper" never call the locksmith again or worry about a magnetic key box letting go when u hit a pot hole or a good bump.

@TerryThrower-ci8ek 8 месяцев назад

Thank you so much for your time explaining how this switch works, it really makes sense now.

@Ottonic6 4 года назад

I am currently diagnosing a 1992 4 Runner drivers window that won't go up, but anyway, looking at the FSM Electrical "System Outline" which explains the operation of the different controls in the master switch it explains that in auto down 12v is sent to the motor while at the same time is also sent to a solenoid (inside the little "Solid State" box on the Mitchell diag. that doesn't show anything) which locks the switch in the down position and when the motor hits its down limit increases the current through the solenoid which disengages it along with the switch... There's a lot more going on with 8 resistors,4 diodes (1 zener), a couple caps etc... I know that won't play a part in my diagnosis, but what you explained really helped me out in direction when I attempt to fix my problem. Thank you for your time and expertise.

@kennethnichols7263 7 лет назад

Great video. I don't have a schematic but what I would expect for the auto down is a self latching circuit. In the old days a relay was used and the switch side of the relay would be put in parallel with the switch. The coil for the relay would be put on the unpowered side of the switch to ground. Once the switch is closed the relay closes its switch side maintaining the voltage on the other side of the switch to keep the relay closed. The latch is now in effect. Now with the window motor this voltage should be enough until the motor hits it end of travel and the motor stalls. When the motor is moving a back emf (electro-motive force) is generated which is proportional to the speed of the motor. This is because all D.C. Motors are also generators. At the end of travel the voltage will disappear and the coil will loose its power and the relay will open delatching the circuit. Now these days the relay may have some kind of transistor circuit to replace the relay. By the way, multiple grounds and power pins may be put on a circuit board due to the limited current carrying capacity of the connector pins. The traces on the board or power/ground planes can be beefed up to carry high currents but there is a spec on the pins which is the limiting factor.

@tecnaman9097 7 лет назад

Paul from my experience attempting to fix taxi cab window switches over many years it just ain't worth the trouble.! I used to bodger them using a points file (remember them) to clean the contacts but it always failed. Only did this if I didn't have one to go. Man, I know what you mean when you say patience is needed!

@stevenhzoll7057 7 лет назад

I could never wrap my head around a Power Probe and I know how they allow you to supply batt+ and - to the circuit under test . Yes the incandescent test light (scope on a rope SMA) is still my go to tool and if you know the current carrying capability of the circuit a sealed beam headlight makes a nice load. I agree that the auto down feature cannot function as wired in the Mitchel diagram. Keep up the great work between you, Eric O and Ivan I might just start to figure some of this stuff out Thanks

@ScannerDanner 7 лет назад

Nice, thank you! I thought maybe I was going crazy with that diagram.

@leifsimmons2464 7 лет назад

I believe the resistor is a current sense resistor. When the motor stalls, current will increase and the voltage drop over the resistor will increase. The "solid state" box in your diagram will be able to detect the voltage difference between "true" ground and motor ground and stop feeding power to the motor.

@swlmmrtn 6 лет назад

I have seen these problems so many times in my time working on cars. Everyone should really look into taking the switch apart and getting to know the contacts inside "rocker" switch. They get built up with so much dust and gunk that they simply don't make contact. The down contacts are completely different than the up contacts inside the physical switch itself. I'll bet I've cleaned upwards of 50-60 switches for people over the years and got their windows back to perfect working order with simply contact cleaner, small brush, (sometimes toothbrushes work best), and some dielectric grease. Give it a shot on a known bad switch if a junk pile, you'll be amazed how well it works and how little effort it really takes. Saves money and customers LOVE when you can fix the little things instead of replacing.

@rhkips 7 лет назад

No doubt Pete's a sharp cookie! I just worry that I see so many cars you troubleshoot there with dead batteries. Does Pete feed off DC electricity, and just him being around drains all the nearby batteries? ;D Great video, Paul! The confusion with the Power Probe turned into an excellent teaching opportunity for you, and an excellent learning opportunity for us. Total win! Though, you really should carry around a sheet of 120-grit sandpaper in your glovebox; works great for cleaning dead contacts and a myriad of other things! 120-grit is the WD-40 of sandpaper. :D

@cwj9202 7 лет назад

I would assume the solid state device serves as an electronic latching device during the auto down function, and so that part would not be displayed in the electrical schematic. I prefer to utilize my DVOM, not the test light, to check the loaded voltage readings and see the loaded ground circuit voltage rise. Good video as always. Keep up the great work.

@nemanjadzombic6101 6 лет назад

On 500 likes statistically there has to be certain number of dislikes. But 31 is a bit to much. I guess people who dislike, they do that because they were thinking this is gonna be simple fix. But whatching it and having difficulties understanding it, make them angry. I can't possibly see any other reason to dislike this video. It would be really interesting to read explanation for hiting dislike button. I like simple solutions but if there is no one, what then? Parts changing - You're definitely on the wrong channel and that's not autor's fault.

@roadkill5333 7 лет назад

I've read the schematics, good ones, bad ones, and I still can't figure them out. If someone could tell me once how the auto-down feature operates, I could probably do a little better, but..... I e also tried to diagnose a power window switch from a '96 GM pickup passenger side. I finally just left the switch unplugged, as no one wanted to spend the money on a new switch, and the salvage yards didn't want to warranty the used ones. $40 whether it worked or not. So, we just left it unplugged, as it wouldn't operate correctly from either side, but operated from the drivers side correctly, with it unplugged. Great vid, thanks! And thank Pete for taking one for the team, props to him for letting you "play around" with the electrical stuff!

@ScannerDanner 7 лет назад

I usually can, but not on this one. I am positive there are mistakes in that diagram. There is no way that auto down module needs 3 or 4 different ground wires.

@roadkill5333 7 лет назад

ScannerDanner, I wonder if a different source would show the same diagrams, or if there is something wrong with the factory ones? I discovered a factory issue in a motorcycle factory repair manual (not an aftermarket, Clymer or other brands). Mistakes can be made anywhere up the chain. Perhaps you could look at Ivan's (pine hollow auto diagnostics) favorite go to source. BBB Industries. Maybe their diagrams show the correct info. It's a free, public source, not a pro source. But it's usually very good. Just another tool in your bag!!

@edwardjames6070 7 лет назад

those switch assemblies are very similar all throughout toyota. I have a 96 land cruiser and an issue arose with the windows. I know that being a 'parts swapper' is not preferred by you, but $10 and an hour and a half of time and I was able to replace the assembly and have it working by using a switch from a 96 four-runner. after investigating the faulty switch I found corrosion at the faulty contact. now I have a spare switch assembly, and more important, I was able to keep the wife happy.

@MrTwisted1977 7 лет назад

the auto down function is simply a latching relay or a basic transistor curcuit if u think this is difficult try working on cars with can bus systems.these old Toyota circuits are just child's play to the right person so basic and bog standard it's boring at times diagnosing them.anyway scannerdanner is a champ for going through it in such depth especially the new techs.

@ScannerDannerPremium 7 лет назад

Thank you but i disagree that CAN bus systems are more complicated. It's just different, same principles apply to testing an output of a power window module on a network.

@picoboo5048 7 лет назад

@billyr9840 7 лет назад

@gvvq-pi5ml 7 лет назад

Hi Paul i think the reason when the switch is in the middle it puts and earth on both sides of the motor, it's kind of like a dynamic brake if you will, they used to do it on wiper motors in the UK in the 1970's to stop the momentum of the motor carrying it over the park switch and carry on working when turned off, when the park switch opened it put an earth across the motor stopping it dead...hope that makes sense...with windows i used to put a bulb in place of the motor as they dont worry about polarity if you put a volt meter in place of it of course it would try to go backward on one side and forward on the other...from Fred in England.

My Buick Park Avenue 2002 front driver switch has quit. Power windows. Door locks. And mirror has quit working. I have purchased a ZKZYEE Vehicle Super Probe KM50 to test with. It has been difficult to find anything on the internet about the fuses. I believe the fuse is in the back under the seat? Or under the dash. The Windows quit previously, and the door locks on the driver side. Then, after about (2) two months the light on the switch began flashing. I tried it and it started working again. Now, it has stopped again. And the passenger side has stopped working also? It is difficult to find a specific video for the 2002 Buick Park Avenue. I like your video. I subscribed.

@alpinewhite 7 лет назад

19:15. In an ideal world, there should be zero resistance between where you're tapping and the car's chassis. But there is small resistance between where you're tapping and the chassis. That resistance is fixed, albeit a very low resistance. Remember Ohm's Law, E=IR (voltage = current x resistance). By allowing more current to flow through that section of wire, the voltage drop across that wire just went up. That's why your voltage went up from .05 to .97 volts.

@madyoza3061 5 лет назад

4 grounds would make sense if all the windows have the same auto feature.(I was confused for a second too when you said that). also what if everyone used the windows simultaneously, you would need 4 ground wires not to burn something out.

@jamesward5721 Год назад

The switch is burnt, but it being bad is a red herring - note how much slower the motor was going up - it's intermittently bad itself & that's what fried the switch - the motor needs changing as well. Cleaning it in this case most likely won't work as it will be the sealed plastic gear wheels that are binding & you can't get at them. If you can make the switch work again, swap out that window motor too, or the fix won't last. :-( I was at the identical all morning today.. BTW if people don't have a power probe ( I do) you can run the window motor with a cheapo 12v variable power-supply, just swap the +/- over to go between up & down, it will run the motor no problem, might get you out of a pinch if you have a bad switch & a window that is "stuck" down. In todays case for me, which is identical to that ^^, I will swap out the switch & the window motor for good used ones, because just fixing the switch will only work for a little while till it fries again. Change both. :-)

@carlosvaldez3874 5 лет назад

Hi, good video, i have installed 2 power windows to my manual windows. Passenger and rear behind passenger. Have not installed the driver side with master switch, my question is, does it need master switch on driver side installed in order for all the other windows to work?

@leedress2187 7 лет назад

brake clean would've cleaned up those contacts.. Just kidding. I always have a can of quick dry contact cleaner around for stuff like this. i think you had further damage away from the contacts though.. . love your thought process though. Keep up the good work!

@jpintrick84 7 лет назад

you ever run into a broken wire in the door jam I run into that all the time wear the harness goes into the door the wires Flex a lot and end up breaking inside the casing talk on them a little bit the broken one will stretch just fix that on my Ford Explorer only took 2 days LOL

@arcburn3364 5 лет назад

I never carried a spit cup for my chewing tobacco in my welding trucks, so I gave my drivers side window switch a workout.

@little739 5 лет назад

Hello, Paul If you didn't get battery voltage in the down position of the red wire, would you still apply 12v to the green wire in the UP position? With perseverance and your guidance, I now understand the diagram and have answered my own question. Thanks for the video.

@viktorvik1973 Месяц назад

nice!

@alpinewhite 7 лет назад

The way I would've done it would be to put a voltmeter across the green (+) and red (-) wire. In the "up" position, you should read +12volts. In the "down" position, you should read negative 12volts.

@jackshea6937 Год назад

Yes! - Why not do it the easy way? Save watching a 44 minute video, (which is great), but speaking for myself, I'd prefer to just get on and fix it - life's too short.

@josepeixoto3384 10 месяцев назад

There is no neg. 12V ; there is ONLY +12V and 0V(ground) but i get what were saying

@alpinewhite 10 месяцев назад

The voltage you read on the DMM is the voltage of the red wire relative to the black wire. If you switched the red and black wire, you will read a negative voltage.

@BigMac2222 7 лет назад

Aw man I was rooting for you too. I've been there with "component" repairs but sometimes it's worse like when you put the switch back in and nothing works now lol.

@ScannerDanner 7 лет назад

yeah, it was disappointing that I didn't fix it. I'm sure if I spend more time with it I could have. But at least I was able to show where to clean it for others in the future.

@jaakkomarin1789 6 лет назад

Could the resistor inside the switch be a shunt resistor for the autodown solid state circuit to be able to measure current flow of the switch via voltage drop across the resistor?

Even though Pete is learnig too thanks Pete

@freddyflores6412 7 лет назад

I always just use a multimeter to diagnose window problems . Just back probe both wires at the same time and then push switch either way . Then look at your voltage reading .

your probe has power feed test and ground driver test it calculates resistance in the circuit and gives you a reading in ohms

I'd guess the resistor is there for the "auto" feature to sense motor current, which seems redundant since the grounds go to the "magical solid state circuit" or the diagram is plain wrong/missing other things

I agree that the diagram does not appear to reflect the circuit which holds the power on the window motor to travel all the way down, or all the way up automatically. My guess is that it will be some kind of transistors or FETs in parallel with the manual switchs. It is also my guess that the resistor in the diagram that is more than likely clamped by the diode (notice it's in the circuit with reverse polarity) is the circuit that tells the solid state control when the window has reached the end of the travel. The amount of current through that resistor will increase sharply when the motor reaches the end of the travel creating a voltage drop seen by the controller to turn off the window motors. Typically a diode is used as a clamp to prevent the voltage drop from being too great due to high current draw thus damaging the input that monitors the voltage drop. Regarding the circuit board being damaged, what I believe we're seeing is not burned connections, but instead soldering flux that was not cleaned off. It could indicate an attempted repair in the past, or a rework at the factory due to defect.

Great insight! Thank you. I only mentioned the "burnt" contacts for the untrained eye. That would be the first thing they would see and I wanted to make a point that, that was not what you're looking for. You would be correct, "burnt" was not the right word to use.

@fredflintstone8048 7 лет назад

Oh, and I forgot to mention, great video! I really enjoy the discussions about the voltages found on grounds, loaded and unloaded, and how those things can help us determine a problem. As you point out, the amount of current flowing through a circuit will determine the voltage drop so the more current the higher the voltage will be above ground, or battery negative. The same holds true on the positive side, or really anywhere in the circuit. The perfect wire, or circuit would have zero resistance, but that's never the case. Wires, switches, connectors all provide a little resistance in the circuit and will thus provide a voltage drop proportionate the the amount of resistance, and the amount of current. Ohms law. It's a thinking mans game, and rewarding as well when we understand how it works. We need the money of course, but it's satisfying to work on these things when we come to understand what's going on. Again, thanks for sharing another great video.

Early 2000 GM trucks are bad about solder joints cracking in the abs control module. I pull those all of the time and resolder them. Easy money all labor.

I was wondering about the "GREEN" wire you measured. It looked like it was green with some sort coloured spots on it rather than solid gren. Looking at your schematic , there is at least 1 green wire with another colour combined with it as well as a solid green So my thought is you may have measured the wrong wire when testing.

The extra grounds are to help carry the amperage and keep resistance and heat down

Paul, I have a PP4, if you read the owners manual, it states what the led lights mean. It can be tricky to learn all the features of the PP4.

@ScannerDanner 7 лет назад

yes it can for sure.

Sir my car i20 windows motor connector has 6 wires on it. How to get the wires for roll up and down windows?

@blingmotions6996 2 года назад

I was checking a control like that one but no doors work no light in the control, only the door lock button work nth else and i fine know broken fuse..plz help

@selador11 4 года назад

I have this car. I have this problem. Just started watching the vid, hoping to get a solution. Just a remark, first. That auto feature... Is that "auto" light supposed to ALWAYS glow dimly? Mine does. Always. Key on, key off, key completely removed, everything turned off. The light glows dimly, no matter what.

@josealzurut2956 Год назад

Hi good video, I have the same problem with the driver´s windows (IS there a fusible or relay to check it?. I cleaned all master swithc window

@konquerorx 6 лет назад

Mr Paul! Just a question sir. I have a Toyota Camry 1996 equivalent called a Toyota Windom. I'm not sure if it's in the states. Basically it has these frameless windows. Similar to the Subaru's. So when you close it, the window suppose to drop slightly, to shut the door, or open it. I've tried to initialize the windows but that did not work. So I'm unsure how to approach this one. Thanks in advance sir

@verajavi12 6 лет назад

polarity led lights have also threw me off on both low volts= no red led light and no green light when expected because of voltage thresholds in power probe internal circuitry.it was really bad on power probe 1,later power probes had a digital voltage reading that enable u to trust the voltage reading more than the red or green LEDs.often times old school test lights are just better because of simplicity.

Where do I go to get some wiring diagram!

@hyeeagle 7 лет назад

Note: don't try to fix TOYOTA window master switches,because they have recall ( factory defect ) inside switch buttons get melt and stop working,sometime even worse they get fire and burn door panel and wiring ( I seen it ) So when you find window master switch is the problem check with dealer for recall or TSB before you do anything or if you like to sale window switch that's different story. Also you can change window switch circuit board if inside window switch is not melted. Note some of Toyota master switches are or very been checked by dealers as I mentioned recall and installed one way screws which is no one loud to open except dealers.

Resistance in series voltge drop over each resistor the motor was dropping the majority of the battery voltage as lower resistance than the one in tne switch the 0.97 volts is the voltage drop in ths switch the ground on the other side of tbe switch resistor will be close to 0v

@rku840 3 года назад

I doubt the circuit diagram is complete, where is the thermal switch? I have my camry drive side powered window problem. When going down initially no problem, but when going up a short distance it stops, then I need to wait for few minutes before it can move a little bit up again. To fully close the window it has to stop a few times and each time a few minutes before I can reactivate.

I'm really surprised you don't carry contact cleaner, it's amazing at removing carbon deposits!

@ScannerDanner 7 лет назад

I'll add it to my toolbox! This didn't look like something any cleaner would help with.

@hellomoto8203 5 лет назад

Hey Paul how can you address excessive voltage drop in this situation? Assumed source voltage from the battery is at full charge, would you find yourself chasing wire for excessive resistance, like the door jam?

@ScannerDanner 5 лет назад

Give me a time frame to check on your question. Thanks!

@hellomoto8203 5 лет назад

Thanks for your quick reply! During this video, I was thinking about what would you do if when applying the load (using the window's switch) you saw 4-5 volts instead of 11-12, or in your case 8-9 because of a strained battery. My thoughts are corrosion at the connector, moisture in the wire at some point perhaps..
