99-02 GM Cluster Repair unusual fault 

For contact information follow this link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-T_2WnJMsZaU.html

I have been dealing with a faulty cluster on a 01 silverado diesel. Recently bought the truck and needed the odometer fixed to title the truck. The service screen and odometer booth where not working. Was at a loss until i saw this video. After a close examination of the board with an ohm meter . I determond the same diode was bad on my cluster as this video. I managed to get a diode that ohm @ .533 that was close enough to the .60 that yours showed. Installed it and all is good. Powers up and functions as it should. Was also impressed with the mileage being lower than i thought it would be. Thank you for the information contained in this video.

Thanks for posting this operation. I just bought a 2000 GMC and have a cluster issue. So I’m absorbing as much info on this, before I jump into it. So knowing other issues ahead of time helps so much when in unknown waters. Just to share another known issue with these things, there’s a black & white (ground?) wire going to the main plug on cluster that fails. It goes to the back of the engine some where. Not sure of its failure origins, but wanted to share the knowledge. I made sure I liked 👍 and subscribed to your channel.

I love the videos! Having a 1999 Silverado when either directional is blinking my voltage gauge bounces just a little bit on every blink. Would that be the cluster or something else?

So how do you fix the gauge motors in these years? I need mine replaced. Thanks for your videos.

Hi yes good video!! One question though if you have this type of problem on the vehicle will it cause the vehicles battery to drain overnight?

Love your videos man but I was wondering if you could maybe show a video on replacing gauge motors on a 99-02 gm cluster?👍

What pins did you use to power and ground this cluster? Or do you have a wiring diagram or pinout for your plug? the pinout I have is incorrect.

Thank you for getting back with me I'm going to do that tonight. thanks again

Great video very informative. I have a 99 Chevy that the odometer display will only show anything if I push the reset button very hard for about 30 seconds. I was just going to replace it, do you think it could be caused by the same issue. I’d take it in but I use my truck too much to be without it at all. I generally do all my own repairs. I’m no technician I’m horrible diagnosing. However I’m a good mechanic I can swap parts.

HI Jeff, thanks for sharing all of your awesome videos and help! I've browsed through several but cant find my issue. Have you seen a cluster in this 99-02 range that displays solid Security light, Low Fuel, and Battery light. But the truck starts and runs perfect (so I dont think it's Passlock), fuel guage shows empty when full, and also have an ABS and Airbag light. Then the security thing drains the battery dead over night. Someone in a forum said they swapped clusters and it fixed it, but my cluster solder looks great with no burns or anything unusual. Thanks so much!

would you tell me what is the wire that turn warning low oil level on when oil pan is low?

I have an 02 Silverado and recently replaced the gauge bulbs with leds in the twist sockets drove it for a few days then it blew a the transistor by the barcode on the board but I can’t find one or any info on it, wandering what I can replace it with

Finally, somebody that knows this stuff. Thanks for the video ! ! !

I loved the vid, more informative than any I seen for this yr. But, if you could slow down when you show the diod discolouration issue it'd help. No other complaints, ty for the help

Nice video Jeff. I've never seen the diode go bad either.

I have a 2000 GMC Sierra none of my gages work on my cluster you think it’ll have the same problem with this cluster ?

Hi Jeff: I love watching your videos for the sheer talent on display -- but I have a question: What is it you wash your work with after each solder? Some kind of alcohol? And when you lay down a new 'pad', are you putting on some kind of liquid flux first? I'm not sure which substances are in play here? Can you advise? Thanks! (With your help I've already repaired the lighting in my 2001 instrument cluster in my Olds Aurora)

Thinking about changing the bulbs in my cluster but after watching your videos I’d rather send it to you! Can your provide shipping info?

I have a 2000 GMC and the oil pressure Gauge goes to the 40 PSI when I the turn the truck off. Is this cluster drawing power when the key is off. Thank you for your time and videos.

Hi. My oil pressure gauge has been bouncing back and forth for years now and now my PRND321 display is flickering . I have a video on my channel showing the issue. It has a brand new crate engine so its not the oil sensor. Is it more than likely the air core gauge going out or the sensor?

Hey brotha, I have a 02. The speedo nor the odometer goes up. Could that still be a step motor issue? Thanks in advance.

What wires did you power / ground d to bench test your clusters?

What would make that part go off when starting the truck or key turning on

Hi Jeff, I just bought a used 2002 z71 chevy, not sure how I missed that some of my cluster lights weren't working :-(. None of my upper left corner strip or upper right corner strip as in this video lights are not working except turn signals in that area, everything else seems to work. Any ideas, or where I can send it for repairs? My gut is also telling (did this guy swap otu the cluster for something with less miles) :-(.

Hello, i wanted to ask you a question. I have a 2003 Suburban another vehicle cut me off and I had to slam on the brakes I slammed them so hard that a rusted brake line burst at the exact same time my fuel gauge went to the line above "E" and the light came on. I thought that the level indicator might have got jammed because of the abrupt stop but my mechanic checked it used a new pump & sending unit and a spare cluster he had at the shop but the fuel gauge still reads at the line above "E" and the light is on. When you start the truck the needle looks like it goes down a notch to "E" the back to the line above "E" at time this occurred I had put 20 gals in the tank. Any ideas as to what might be going on? Thanks for any thoughts. Mac

I'm having an issue of keeping my cluster lit up. I have a 99 sierra and the PRND321stays illuminated for about a minute after unplugging and replugging the cluster then it shuts off again. I don't see any bad soldier joints. Please help.

Jeff, your videos are very informative. . I am replacing the needles in my 99 sierra cluster. 2 of my air core motors free spin like you e shown in your vids. In one, you used a syringe and oil to form them up. Can you tell me what setup you use to rejuvenate them? Than you, Bill Dalbey

Can I remove abs bulb on my ‘00 cluster? Did a Straight axle swap and no longer using the abs sensors for the front wheel hubs.

How can I get in touch with you. I have a 00 sierra 1500

Is it possible to change the color of the PRNDL display from a 2001 Suburban? Or any way to enhance the clarity? Have a 300k mile cluster and the PRNDL display is looking very tired. Not sure if it's UV that's burned the clear coating or something else.

Can you do a video on a 99 f-150 cluster with tachometer for a 4.6l v8 I have a odometer with digital read that fluctuates on or off and mid way and sometimes it works well I heard it would have loose solder on the connection pins that give the signal to the display.

Great Video. I have 2002 Suburban that makes a pulsating clicking noise that goes away when I dim the interior lights. Do you have any information or video on this issue. Thanks!

Jeff, I have an 02 Tahoe cluster that is possessed. Nothing works on the cluster except the check engine light, no gauges, no display. When the cluster is plugged in, random things happen like the rear AC blower will come on, the door locks will click, and there are odd noises behind the dash. The battery will eventually go dead, unless I leave the cluster disconnected. I tried reflowing the primary plug header and also the fluorescent display header, but it didn’t help. I purchased the truck dirt cheap, because the PO couldn’t figure it out, and he says the thing only has 75k on the clock. I’m going to try a known working cluster in it today, to see if maybe the issue is in the trucks wiring, as I don’t have a test setup. Any thoughts on this thing? If the good cluster checks out, I would like to send this possessed one to you.

Jeff, you seem to know these 99-02 clusters, can you tell me where to locate the 25020 chip for the odometer on this board. I'm familiar with the 03-06 clusters but cant seem to figure out where its located? Could you point me in the right direction. Thanks.

my dash illumination is intermittent on left side of cluster. assuming are bad soldering joints?

I've got a 2002 and i replaced the air core for the oil pressure, well i screwed up and messed it and another one up so the needle is now way off. and i've been looking and can't seem to find out how to re calibrate them

I've seen that diode fail a couple of times. I doubt it was related to the torn trace on that LCD data line.

Hey do you you have a video of recalibrate a 99 Sunfire gauge cluster

Is there a way to keep my Stability Control error from lighting up on my 2002 Escalade message center? The ABS/EBCM Modules are no longer available for it and I don't want to spend anymore money on it having it rebuilt.

My dash cluster message center and the mileage part work when the want sometimes you just got to tap the cluster and they light up and sometimes it goes back out any thoughts on what would cause this

So I have a 99 gmc sierra 1500 5.3v8 recently my gages sometimes while driving or sometimes just idling the truck will run stay running but my batter light comes on my volts stay up but my fuel say empty my rpms says 0 and then when it decides to come.back everything works like normal but one morning I started it up let it idle and my battery light came on. My gas my rpms needle started dancing up down up down my milage started to flip from trip to odometer trip to odometer any thoughts

I still need more information about it I wanted to see how to swap it out the (PRND321) (diode) my meter is reading right at the number on the resistors and makes a sound I really don’t know what’s the problem with my Diode…

Should put a pic chip with your shop logo streaming to the vfd or lcd on startup.. lol you did fix the “unfixable” .. Lazarus Cluster

You talked about the gas gages on the 99-02 clusters. Are you familiar with the “hummingbird” effect in the 95-98(00) Clusters for trucks? If so, what is your thought on that? Have you repaired any older boards like those?

What is the resting position for the oil pressure gauge when the cluster is turned on on the bench test but not connected to PCM? The one I have the pointer goes to 3pm mark :)

on my 99 silverado i remember the odometer being dead when i bought the truck, i pulled it apart soldered some broke/cracked connections, put it back in the truck and about had a stroke. Discovered the damn thing had 319,000 on it.

I have the gas gage problem I replaced the gas stepper motor. I tanked the car full and put it in Ignition Position on and set the needle to full but when I shut it off it goes to the bottom right. Could it be the sending unit for a 1999 Buick Regal? And were is that? Thanks!

Hi Jeff, I have repaired the solder joints on my 2000 Silverado cluster and I am trying to find a pinout to bench test the odometer display on the cluster only. Is there any way you could help me figure that out? Thanks so much I’m advance. Great information in your videos.

Hello, Love your video. I have a 2002 chevy silverado 3500 with instrument issues. Odometer and gear selector not illuminating, diesel gauge not working, trans Temp doesn't seem to work, and temp doesn't seem to work. Battery light stays on. Volts gauge oil gauge, blinkers, mph and r p m seem to wrork. If I tap on the dash the Rpm needle jumps and the blinker arrows come on . Can I send my instrument cluster to you for repair?

I have 3 1999 Silverado clusters I need gone thru can you do it?

Hi I have tried to fix my dashboard cluster and I'm not able to get it fixed. I can't see mileage and what gear it is in

I have a display from a 08 skidoo summit , would you be interested in looking at it.

The cluster on my 2000 silverado the display and lcd screen works sometimes, flickers or freaks out sometime and is black (blank)most of the time. Would you be able to fix mine?? And if so what is the charge??

where can we get the motors for these clusters, i have searched with no avail. Also, is there any way to recalibrate them without a tech II? i want to change my needles out as they are very faded but dont want to change up the readings. Thank you, Brendan

What kind of test simulator you got there?

Hi Jeff, I have been struggling with my 02 gmc sierra 1500 gauge cluster for months now. The speedometer and odometer are not working right now. When scanned with a computer it has diagnostic trouble code P0608 which says to check the wiring between the instrument cluster and the PCM. I have hooked up a multimeter from the PCM to the gauge cluster and the wire has continuity in it. I have taken it to a GMC dealership and they said that the speedometer fails their sweep test when they send a command to sweep the speedometer. They said it jumped straight to 50mph when it should sweep all the speeds slowly. They wanted to replace the stepper motors in the cluster. Should I replace the speedometer stepper motor? Any thoughts on why the odometer is stuck at 149k miles? Anything else to check? Its funny that the code pulls up for a bad wire connection between the PCM and cluster, but I'm leaning towards instrument cluster problems. thanks!

Do you know what D2 does on the circuit board? Mine shows 100 mV in both directions. Also do you know what size it is? I'm not sure how to tell. Thanks :) FYI ~ I have partial failure, the PRND, Speedo, tac, and possibly other guages don't work. Oil pressure, turn signals, and voltage appear to work (not sure how to test others without a bench setup).

What would be your pricing if id send you a cluster to get worked on? Got a 01 gmc 1500 and the display does the same thing.

How can I get a cluster to you for repair the odometer does not work and gear shifter light does not work

Can I send in my cluster for repair, and if so how can I contact you. Thanks

That strange symbol is an alien attack message. Prepare! ;)

Any way I can some info when to send you my 2002 Chevy Silverado 2500 hd cluster ? I tried the ground but I keeps acting up . I hope you are able to help me 🙏🙏

Question, I have the same board and probably could just follow your steps because I have the exact same issue. Problem is time to tinker with stuff like this. Do you offer a service where I can send my cluster in to have it fixed?

Hey Jeff im having an issue i hope you can help with. I have a 2002 cluster just like the one in the video, i have removed the eeprom to correct the milage from my old cluster and i believe i have fried the eeprom trying to read the data. Can i use a 95202 eeprom to replace the old one? Not much info on finding out how to read those older chips.

What if you have replaced several sending units? What could it be

How are you sending the signal to the cluster for the gas level? Are you using a piggyback from a stock ECU?

How did you build that switch to turn on the power to the instrument panel I’m trying to change my leds

Does the cluster store the mileage information?

Would you know why my fuel gauge takes over an hour to register fuel on a 2001 Silverado? I replaced the fuel pump and now it takes forever to show how much fuel is in the tank. Thanks in advance

i replaced the needles on my 02 yukon and i noticed that the speedometer needle is a lil off. When the meter is at 20 it feels like i’m going 30. Do you know why this could be ?

Can u help me out ... I have a 02 Escalade and the speed needle doesn’t move and the mileage doesn’t turn either... but everything else works fine just those 2 things.....

Question!!! Where can I get the twist sockets for the replaceable bulbs for the 99-02? Mine has the Wagner PC194 bulbs which are soldered to the bulb sockets. Someone had replaced one of mine because it was removable, but there are no identifying marks on the socket besides a 6 or 9↕️. It is grey. All the ones I've found online are the wrong size or have the locking tabs in the wrong place.

Do u know what wire the temp is ?

I have the exact same issue with the massage center and PRNDL but when I press the dash for a moment it comes back, so I am guessing a bad contact or solder joint, add to that I have a faceplate that's totally warped, and cant seem to find someone to fix the the message and PRNDL intermittent AND the faceplate at the same time, very frustrated. issue

I have a silverado 92 and I put a 2000 dashboard on it and I want to change the cluster from 1992 to 2000 how do I connect the harness pins

I am curious if you know why so many of these can cause parasitic draw. It seems like everyone on the internet says they are the most common cause of parasitic draw in those vehicles. But why is that the case?

I'm looking for some diode info on a 03 Tahoe gauge cluster. How can I find the info to get a replacement?

He gets right to the point good video

Where can I buy the stepper motors for a 2002 Escalade? Seems like everywhere I search, leads me to 2003-2006. Do you have a link? Thank you

Can the air core motors on these be "fixed" or do they need to be replaced? I have a cluster that the oil press. gauge is erratic at idle, but will move to a solid position once you are moving.

Can I send you my 99 cluster? If so, how much to repair display and possible other issues that might be wrong with it? And also, what's the turn around time on a repair?

Awsome videos for sure. Mine just out of my wheelhouse

I had my cluster out earlier today to chase down an electrical issue that seems to be an inoperative BCM, and out of curiosity, pulled my cluster out to see why my Check Engine, ABS, and Brake lights have never worked since I bought the truck. Someone unsoldered and removed them from the board. Sigh. Any idea what LED should go in place of them?

Can I put one like that on a 99 Chevy Tahoe ?

You had mentioned in your video that you have people send you their cluster I would like to know more about this and the possible cost

I have a 2001 yukon with LCD screen and I failed emmission due to a no mil light. Do you know if those clusters show check engine lights?

Can you change the greenish color of the park drive reverse screen thing to a different color

Ya my 2000 suburban gas gauge stoped working but it was after changing the fuel pump so it was probably my fault but it was cheap but I'm not droping the tank right now so I just fill up and reset the trip

What type of diode was used?

What kinda led bulbs would those be and how many do you need for a full replacement

Not sure if you answer questions, but if you do....how much would this type of repair cost?

What setup are you using to drive the fuel gauge? They are bus controlled on these aren't they? Thanks

do you do repairs still? I have a cluster giving me peculiar issue. maybe you can help. hope to hear back from you.

I get nothing on my cluster until I push the odometer stem.. any ideas?

Hey jeff my cluster speedometer gauge is not working and the mileage is staying same and not changing. Would you think it is the sending unit?

Hi I have a 2000 gmc sierra having trouble with the message center and prnd321 flickering when I'm driving on the road over bumps.

Sir,I have the same exact issue with a diode, where can I get a 4001 diode for replacement.

Love the video but am also have trouble with the Gas And Temperature gauge not working in also battery light stay on please help

Will a 2002 GMC HD 2500 instrument cluster work in a 2002 GMC 1500 Sierra? Trying to get a cluster with trans temp gauge. Or, can a trans temp gauge be added to my cluster?
