CHEVY TRUCK WIPERS STAY ON DIAGNOSIS AND FIX 

This channel has to be in the top 10 for automotive diagnostics

Dude, I'm addicted to watching your videos, seriously. You (in my opinion) do such a great job articulating & explaining details which is why I'm addicted. You really break things down to the most smallest of things that can easily be understood for most. I would really like to see a video that breaks down what everything is and means on those electronic diagrams, I'm sure there's viewers who follow you just great but as a beginner in diagnosticing using the electrical layouts. Would like to learn and understand what all I'm looking at as I follow along. Keep up the great lessons, much useful and appreciated 👍

Thanks for the time on the explanation on the diagram, I like that some time people explain but to fast

Wow, great job guy. You really savy those blue prints. And how the heck did you come to realize the drawing was wrong. I would never have assumed a drawing could be wrong! I'm impressed.👍

Great video. Most people have no idea when it comes to electrical problems!!

Keep up the good work..I can't believe you didn't fumble unless you edited . Regardless we are human . 10 plus years of watching various mechanics you get the 2nd Addy boy I ever gave out.

Signal tracing through the circuit. Works every time!

i have struggled with diagrams quite a bit but with your guidance in this video it all makes sense.Thank you.Subscribed

Great job on explanations. Clear and easy to follow. I always enjoy watching you work through these problems.

Helped soo much couldn’t find a wiring diagram anywhere! Thank you for your help:)

That was excellent. Thanks for taking the time to go through all the steps, explaining the wiring diagram, and flagging the issue on the Mitchell diagram.

I like the way you run down the wiring diagram to explain how it flows ... good job and thx for your time 👍🏻

Just found your channel and love your videos! Your diag process is helpful and easy to understand. I work on lots of brands and have found many discrepancies with non OE wiring diagrams. Currently I'm at a transmission shop so I'd love to see how you go about dealing with sensor/solenoid/internal faults, particularly on Japanese brands. Thanks for the quality content!

Nice diagnosis and explanation. I hope you fixed both of the wires that you cut.

This video is absolutely amazingly helpful! I’m trying to diagnosis a wiper issue of my own

I am learning so much from you, thank you!!!

Excellent troubleshooting, well explained. I found myself pausing the video to think the problem through for myself, then I would resume when I had decided what to do next. Side by side, the Mitchell diagrams are much easier to read, but if the details are not accurate there is a problem. I wonder if those PCB relays are the future, it will make repairs and even diagnosis significantly more expensive. It would have been fun to tear down the old fuse box to see what is inside. Microscopic diagnosis is a whole new field, interesting to follow the new technology.

Great diagnostic video. Very well explained. Thank you for sharing.

I look forward to your videos. You do a very good job of explaining complicated concepts.

very informative. I'm an "electrician" in the military so it's easy to follow along on the diagrams. I wish I had access to all of that. I have a 2007 silverado with wiper problems that led me here. unfortunately my problem is a little different so I'm still stumped. the wipers don't return to park. and no matter what intermittent setting I put them on, they run full speed. it seemed like it would be the switch so I just replaced it and the problem persists.

Nice job explaining. I would have liked to have seen the specific cause of the problem in the fuse box. At least an autopsy on the fuse box after it was taken out.

I'd like to have seen the install of that fuse box wiper controller. Good video

Excellent video, excellent job on explaining everything that went into the diagnosis. Thank you for making this video.

This video is so helpful. Thank you so much

Great diagnosis! Really appreciate the in-depth approach. Liked and subscribed!!

I love advanced diag vids.. I've only seen a few of your vids but I can tell you're legit, like Eric of South Main Auto, Ivan of Pine Hollow Auto Diag, Mr. Danner of ScannerDanner, Matt of Schrodingers box. Some of these damn dealerships can't even do what you guys do.

Exellent the in detail. Never got lost of what u where trying to explain.

Excellent video. Like the review of the wiring diagrams and the logic used to understand the circuit leading to the proper diagnosis. two thumbs up

Best explanation ever thanks man

Very good and thoughtful process, much appreciated!!

Awesome diagnosis!!!! Great job

I'm glad I found this channel. Thank You sir!!

Man I would be replacing bcm, really smart to cut that wire and prove the short to power in that box

Thanks for the wiring diagram training.

Good work my friend. Good to see you back on action. Sam

Good diagnosis and fix! Vehicles are getting too complex to approach problems casually. The fuse box! Who would have thought?

Those fuse boxes fail all the time,I maintain a fleet of Chevy/gmc pickups for a town municipality and I’ve had to replace the fuse boxes on all but one of the 2007-2103s. The fuel pump fuse holder usually melts on them and intermittent issues and codes.....

Subbed! I like how you explain on how wiring diagram work.. you talk kinda fast but im getting better at reading at wiring diagram. They’re kinda hard. Look forward to your channel!

Good channel with great diagnostics skills we r learning a lot...big like and thank u

nice diag. Car schematics are a little different but your explanation was easy to follow. Fairly simple circuit.

You're doing an excellent job

My 2018 3500 6.0 does this too. I’m gonna diagnose it with your video but for some reason switching into and out of 4x4 while fiddling with the blade speeds usually fixes it

You are doing a good job explaining. Thanks

I've seen that quite a bit with Mitchell diagrams. That's why I try to get a factory diagram when possible. Don't get me wrong, Mitchell is usually spot on, but I have seen the errors quite a bit. And I was thinking.. It showed that it was on high speed but it sure didn't look like high. then again, that could be caused by under-powered battery. And another great video. Thanks!

Excellent Video Man , Thank You ..!!!

You do really good work! I’m hoping you can do a parasitic drain video. I’d really like to know what tools you use and how you approach it. If I’m ever in your area I’m gonna stop in and say whazzup! I’ll buy lunch!

Excellent diagnosis my friend

Well explained! Thanks for sharing 👍

You're the best bro. 🎉

2000 chevy Silverado wipers frooze to windshield , and died Not the fuse. Tested Motor and figured out if I run a ground from motor housing to ground they run. Got high and low speed but only shut off once turned on by shutting car off . The motor Circuit board Multiswitch Fuse box builtin relay. You'd think this frozen wipers to the window issue has happened alot and point to an issue

THANK YOU FOR THE VIDEO , GOOD DIAGNOSIS .

You've got an awesome channel. Thank you for all you do for the rest of us.

Great video, I have a similar problem with my wiper washer won’t shut off after replacing wiper motor. Replaced motor because washer stopped working and I knew the washer pump was good got any advice for me on what’s going on thanks

good job i leant a lot iam am student in re traniag on elerictal auto wiring ,Thanks

Awesome!!!!! What scanner platform are you usthat data is priceless

Great explaination

Thank You Eric , all love to you form your fans in Saudi Arabia

fantastic work. thanks brother.

I'm learning a lot. Thank you!

Very VERY thorough investigation and near final diagnosis. To be clear, you’re leaps and bounds ahead on the level of knowledge you have compared to me. My personal opinion (as if it matters) is that you went through a whole lot troubleshooting to narrow it down beyond every main component that most would have replaced and failed. But with that said, you were all the way to finding the last tiny puzzle piece and replaced the entire fuse box. Just out of extreme curiosity, why not find the shorted wire? You were literally right there, everything apart, couldn’t be closer, ruled out motor, switches, BCM, loose grounds, replays, etc. and all the way to te final gray wire as the culprit. Why not trace back that one wire? I truly don’t understand! With all that knowledge, access to diagrams, scan tools, and diagnostic equipment, you bought a whole new MAIN fuse box? Please tell me what I’m missing? I watched every second of your 30-minute video, while rare for me to do, you held my interest, taught me a lot, and stopped an inch before the finish line. Honestly, was it more about the billing, or was there seriously too much to go through at that point to narrow down that last piece? When I say “billing”, I mean, a customer might not understand the cost if you charged them $500 for diagnosis and repair of a tiny wire, so better to bill for an entire fuse box so it’s obvious (to the uninformed) that installing an entire fuse box could be very costly. I mean if they watched this video, they’d certainly have realized all the time and necessary equipment required to find that short. Again, very confused if that wasn’t the reason?!?! PLEASE?

You are doing a great job pal. Regards.

I have had this come to my shop and all I did was blow out the dirt from the fuse box and they stopped

You are one of my hand pick good job thank you

Great video

good job brother!!

Looks like you cut a 2nd wire in there too (or nicked it pretty hard). Glad you pointed out the mis-printed wiring diagram. I noticed the slow speed wiper and you were pointing to high speed lines. Those diodes steer power as well, and should be considered. So... did you find the problem? You left us hanging with this video.

WHAT A SMART MECHANIC WHICH IS VERY RARE THESE DAYS

Nice work man that was very helpful my question is I have an 09 Silverado with the delay setting won’t work the cust took it to another shop they replaced the wiper motor the bcm the multifunction switch I looked at the data it does seem to show 1 though 5 on the delay setting but when you operate the switch the delay still won’t work any ideas on that would be helpful

This is excellent and I took a lot away from it but in the end you had to replace the fuse box to repair this and you didn’t actually show that part. Does this mean the entire fuse box or simply the fuse block that the wiring goes to? I have a similar issue whereby the wipers don’t work at all. The motor and combination switch have both been replaced with no change and I have 12V going into the yellow wire on the motor with good ground but no signal to the green or purple wires. This tells me one or both of the relays in the fuse box is no good.

you did great very very nice work keep up the great videos

I'm having this problem with my 2015 Malibu, I removed the wiper switch on the column, and every plug from the BCM, the wiper power relay pin 86 still has 12 volts, closing it to activate the wipers the only thing I can think of is a short to power in the fuse block... Hopeful it works.

Great job on video .. the ground on the motor for the wiper circuit is there a location explaining or easy test that you can do to test ground n if so where is it located ...

Excellent video, I recently found your site and enjoy your troubleshooting procedures very professional. Looking at all of the muddy water residue it appears the owner may have been out 'weekend muddin' with it and no cover on the fuse block or with the cover in place a poor design by GM to keep water out. At the end you show the NEW fuse block installed with a cover in place. Is this a new cover or the original cover that has been thoroughly cleaned?

The diagram life ! 👍🏻👍🏻

I uave replaced A LOT od that style fuse box for various problems

You know your stuff!

Great job. did the new fuse box come with new relays. I thought about changing out the 2 relays first. Was that a possibility? i am learning so much from you. thanks

Your descriptions/explanations are a bit drawn out. but you are getting you point across and that's what matters. Just need to chill a bit. Is this truck wiring the same as a 2004 gmc sierra 1500 2wd?

Not exactly a planned attack that I expected. You said that a relay had to operate for the wipers to be on. You said it should be on. A simple pull the fuse and see if it clicks would have revealed the relay WAS ON. And your tests with the scan tool revealed that the BCM was not being told to. A resounding EHHH? would have beena good reaction to then cutting the wire. You already new the wipers were ona dn had voltage . Also dont check for power wiha power probe. it applies powers and grounds. An 800 ma test lamp is a better power test. Even thought the realy is soldered in, you probably could remove its cover to see it was operated or welded shut.

What is wrong with these 36 persons giving you a thumbs down even though you fixed the case study.

I'm thinking I have a fuse box cross powering issue. How had was the fuse box after removal?

Do you have to program anything or just pop the new fuse panel in and go

I have the same problem in a 2007 Chevy Tahoe. What do you recommend I do? I turn off the truck and the windshield wipers stay on.

Thank You Eric! Great Diagnostic & repair as always! Just curious ... why You do not check signal integrity and PCM outputs as one the fists diagnostic steps? Back in my collage years... 1980s - professors was saying to us: power and ground first, circuits integrity and surface conditions as second and input and output maps and status as a third step than networks maps and protocols consistency. I`m from industrial automation and robotics,.. but cars is practically the same thing - just complicate in the different way... P.S. Very sad... Your shop is far away from NYC and I can`t be a Your customer...

Just out of curiosity did you hack into fuse box after replacing box just to find the failure? Just itching to know why it failed? Let us know please

Well done thanks for the information

Wipers frooze to windshield they just stopped thought it was the fuse, but no. I ran a ground wire from motor housing to ground without i get nothing. They turn on high and low and the delay works and can turn them off. More often than not you turn them on they work fine in low or high but only stop running if you shut off the engine go back to park. Could this be a ground issue in the fuse panel ?

Good job thanks

I got a 2019 sierra denali and mine go down all the way then barely raise up when I turn them off. So when I crank truck back they wipe one more time then stop.

So do you have to replace the fuse box or a 1 fuse?

Fuck yeah nice working on explaining it bro 🍻👍👍👍👍👍👍

Cant believe you only have 7.25 subscribers. Watch out SMA

I had to change one of those fuse boxes cuss the relays on the board where completely blowed out

Not trying to be critical but, I think it would be a good idea to seal off the areas of wire you probe by piercing the insulator. Eric O. at SMA seals the pierced insulator with liquid masking tape. Also, I don't understand why you had to cut the wire from the BCM. Why couldn't you just measure the voltage on that wire when the key was off?

So is replacing the fuse box the only way to fix the problem

GREAT DIAG ERIC thanks

Gonna replace the bcm good job

Tks love your videos

great job

hey, I have a problem with my wipers are not working any more and I dont know what to do anymore also 3 went in 3 services and problem was not fixed. So one morning was alot of snow on the windshield and wipers went on when I started the engine tryng to clean the snow but got blocked. I have cheked the fuse is fine ,checked motor is fine .... what can it be??? please help me!!!
