GM Cluster Troubleshooting Guide 99-02

Hi Jeff 👋 just wanted to chime in and say that after much RU-vid "U" videos last fall i preformed the A8 ground correction , minimal successes was had , after driving through the winter months with ever increasing random ( hit a bump ) outage/reboot. I slid the closest tool ( an ice scraper) above the cluster and wiggled the cluster connection,,,,, woop woop ,,, 🙌 it worked 💪 . So i left it stuffed in there 😆 worked great till the temperatures climed close to the hondo mark ,,,, so i decided to disassemble the dash again,,,, i know just 4 screws because i had never put the basel back on .... anyway to make a very long story shorter ,,,,, I had read about all the wonky soldier joints on these clusters ,,,,, imagine how surprised I was to find the joints for the actual cluster connector had were bad . I proceeded to resolider those ( yep i did em all ) and to my amazement lol the cluster is now working as designed 😅 thanks for all the work you do for the struggling 99-02 chevrolet silverado lovers out here 💪🙏🙌👍🏻👍🏻💯

Came here from 1ROAD. Subscribed immediately! I really look forward to studying this video, as the parking brake light is out on my 99 Suburban I/P.

Glad to see you back at it again!. I still need to send my 02 cluster in😒

Thank you for this video! All my gauges went out a few weeks ago and I found your video and I tried the A8 ground and fixed my issue thank you so much!!!

Glad your back at it I have a 99 cluster I need to send your way

I really appreciate these videos! I'm learning a lot from your channel.

+1 request for an 03-06 ultimate troubleshooting guide! Just watched you probe the water damaged cluster a few vids back. would be great to know all the test points and expected voltages for novices like myself!

I enjoy your vids. Your knowledge and skills are mad. Your presentation is clear and concise. The occasional cat visit a plus.

Good stuff Jeff, Thanks for putting that all together!

You Dazzled me with this and your other videos. so INFORMATIVE and presented in a very easy to understand (and brief to the point) format. Thank You.

Awesome video. When I did my dads 03 Cluster I jumped through a few videos and got lots of crumbs of info. Good to see it compiled into a nice video. I assume you plan to do the newer styles next?

Thank you! Fix my problem and was right on task! Very professional and right to the point, even showed what it looks like when the problem happens thank you! I had a grounding problem

I figured out the problem my bulbs wasn't getting connection how all of them wasn't doing so is the million dollar question but got them working thank you for your response

Thanks for the guide…..ground wire was what had mine down.

Hi Jeff! Love the videos. What type of oil are you injecting into the air core gauges? Just a heavy motor oil? I have one guage that needs to be done and was just wondering. Big thanks and keep up the great videos!

Jeff, great tutorial. My cluster on my 99 Chevy Silverado battery indicator that comes on intermittently gives me a place to start.

Thanks Jeff. That will come in very handy

jeffescorttlx; My name is Norm, I have been doing stepper motor and some minor repair for about 4 years now, this video is by far one of the most informative yet. If you ever put together a troubleshooting guide for sale Please Let me know I would like to be the first to get one. Thank you keep up the great videos.

Love the vids bro! you helped me out a lot

My 03 chevy cluster is still working. Thanks for doing a great job! I told a few friends to look you up to fix theirs.

Great info. 👊🏼

Awesome 👏🏼 😎 man. Thank you so much for making this one too !

Great Vid Jeff, how about a similar video on 03-06 problems...

Hello.. I have a 2000 GMC Yukon 5.3 4x4 it's a great truck hasn't missed a beat.I was hoping you could take a look at the cluster and make sure everything's how it should be. Thank you

Hope to see another vid for the next gen clusters after the 02’s

You fought one problem. I seen a lot 99-02 cluster back lightning stop working including all all the dash buttons on the dash... I believe it’s the headlight switch because last 99-02 vehicle I worked on had this problem and there headlight switch was bad it wasn’t making connection inside no more, I usually just by pass this problem from the fuse box and all lightning works again but I believe by changing the headlight switch it will fix the problem

You rockstar☆☆☆☆☆ I su appreciate you, your time and knowledge

Hey Jeff, where is the odometer info stored? In the VFD display board or the microprocessor board? Thanks for all you do!

The axillary ground wire worked for my needle gauges acting erratically/jumping. Thanks so much!! On the abs/brake light coming on occasionally, do you find this to be a bad ground to the frame ? I know there are many other issues .. Thanks again for your help and enjoyable videos !! m.k.

Would it be possible to have you email me the pinout on how you got your bench harness set up? Ive tried multiple things to get the cluster to fully power up but I cannot seem to be able to figure out how to get the PRNDL/odo display to light up.

This is THE video for these trucks and their gauge clusters

Great videos Jeff. Thanks for taking the time to make them. My 01 message center is non op.. Everything else in the cluster works fine just a dark message center. Have you run across this problem?

GMC 2001 Yukon XL, Cluster light ABS Light and Brake Lights always stuck on and intermittent fade on the Odometer/PRND321 display. Reset the Fuse for ignition and for now the Odometer light is working without issue. The other two lights. Board issue or actually system issue that needs further investigation?

Hi Jeff, I have a 1999 chevy silverodo when you turn switch on everything works great for a min. or so then the gas gauge and the temp and message center drop. i done the ground replacement but still having same issue .

Ive got an 03 Yukon, the cluster acts the same as this does with a bad ground, would that also be an instance of a bad ground or an internal problem with the cluster?

Could you do a cluster from a 2005-2009 Pontiac Montana SV6? I know it controls the clicking sound for the signal lights. Mine is not working. I would love to know how to fix it. What chip is wrong?

What voltage is a9 supposed to be?

I need help I have 3 clusters and I used to power them with a 12v car battery and the wiring was all over the place and I think it fried the board bc now when I plug it into a truck only the velocímeter and the rpms read and the gas light is always on the other guages don’t even move

Hey Jeff, my 01' fuel gauge is way off, like pointed at the voltage gauge after a battery change, everything else works fine. Any clue on how I could fix it? Thanks

I have an 04 gm cluster that the blacklisting is out until I push on the top of the cluster everything else works fine I just can see how fast I'm driving at night I'm no stranger to soldering any ideas??

I have a chevy tahoe I'm looking to have my speedometer redone some lights are out how long is the wait to have it all done

Hi there how much does it cost to have a cluster checked and air motors service and just replace anything that needs it??

Any reason why cluster wont turn back on after installing led bulbs in a 99-02 cluster.. after installing them they never turned on. I put bsck the stock bulbs and didnt light up either. Thanks in advance💯

I have an 02 avalanche, the fuel gauge and coolant gauge ONLY WORK when I step on the brake. what exactly is going on?

I have something like the intermittent gauge issue, exept the engine light, volt and oil pressure are not affected. Everything else goes off like crazy, all warning lights are flashing and needles jump up and down. Happens after driving 30 min to an hour. Sometimes it goes back to normal after a couple minuttes and other times it goes on for hours, or until i stop the car for a couple min. Tried the ground wire fix and no luck. You have an idea what coult cause this?

Would it work if I put an 02 Escalade cluster on a 03 Yukon please let me know or what I can do thanks

Have you seen where the fuel gauge reads backwards? E=F F=E only problem I have with my cluster. I have an 02 1500 Chevy Suburban. Thanks

I find it very instructive. How can I send you the dash unit. I have 05 GMC Sierra with the common problem the shifter Indicator light or display does not work. Where can I find you? How can I contact you? Thanks

Jeff, where did you get the cluster harness?

@jeffescortlx - Have you ever seen an 03 Gm Dash cluster cause inconsistent left turn signal?

Is it possible to fix a cluster bulb in the Stepper motor area of ​​a 2005 Malibu max LT?

I don’t know if you’ll get this. Can you tell me which pins I need to power a 2000 Chevy 1500 cluster on my bench? Thanks.

waiting on GM 03-06 cluster guide..

I am having the same intermittent cluster issue, however my voltage gauge still works, is that still going to be the A8 ground or another?

Good information i have a 2002 monte carlo the mileage and dive display come in and out sometime so i pulled out the cluster then went to the junkyard and pulled wires from another monte now sure what wire are positive and negative to power up the cluster can help pls. Thank

I've been having issues with my 2000 Silverado cluster. When I turn the truck off, take the key out, open and shut the door, once the dome light goes out, the high beam indicator and cruise control indicator both light up on the cluster and stay lit. It drains the battery. Also the D on the gear select is dimly lit, just barely able to make it out when it's dark. Even if I take the key out and leave the door open, the lights will still come on. Everything on the cluster works fine and normal. I've sent the cluster out for refurbishment, still does it. I don't know if it's the cluster or something else shorting out waking the cluster up. I've replaced the multifunction switch with factory new, still does it. Next I will put a refurbished BCM in. Maybe it's bad?? Idk. Do you know what circumstance would cause these lights to come on and drain the battery? Radio off, security light off, just what I stated above. I'm lost with this one, I have to remove and install the radio fuse everytime I park and drive the truck.

Do you have a video or reference guide to how to wire up the connector to bench test the cluster? I am trying to figure out what wire I need to connect to turn the cluster on with out using the vehicle power

Where can I find the info to send a cluster in? Thanks

Hey,can I get my gm computer PCM to control the hi-beams,Brake,ABS, Security lights or no?

I know ur not gonna see this but I have a 2000 GMC and I have an issue with no odometer display. I saw ur video on how to fix it but I ended up putting in a new cluster and the issue is still there… but when it rains my cluster ends up working again showing the odometer and the gauges. I’m not sure if you ever experienced this but plz help

Hey Bud, I have a 2000 gmc sierra 1500. I just replaced the stepper motor but my display says low fuel when it isn’t. Any idea or is it my damn sending unit. Thanks

I had new steppers and leds but then it was working but a wire touched and nothing works now except lights what would cause that is there a fuse are something I can solder off and on are diode

My prob is my fuel,trans and motor Temps don't work. My old port don't work now and the box that's around the display don't show so I cant see what gear I'm in but I can see the gears. Then driving the rpm and speedometer will work then flicker but still works. Has abs light on everything else works fine

I do have one more question my htr a/c fuse doesn't work at all so I was wondering if there's anyway to buypass that fuse

4:06 anyone know what fuse it is ? Having the same problem where my cluster only works when you press the trip button

I used to get a split-second signal loss of the cluster when hitting a bump but as soon as I grounded A8, the problem became much worst. The needle readings are completely off and when I turn everything off and remove the key from the ignition they still flicker slightly....:( should I remove the ground from the PCM and only use another one??

i just sent you a. video to your email about my cluster it shows exactly whats the issue

How about the lights on the 194 bulbs don’t work how are they powered

Hi I have a 2002 Chevy silverado I replaced the cluster and it won't show mpr,rpms, or Andy displays besides the engine service soon when I turn the ignition key

What if the cluster light doesn't work but everything else works fine I've replaced bulbs

Any idea what would cause the speedo, tach, and fuel gauge to no longer work all at the same time?

Video of fixing first problem? Only confused on where to put ground.

I changed my back lights to LED. And now my fuel gauge is stuck on E with low fuel warning on. Gear selection highlighter not working. But the passenger seatbelt, abs, Battery indicator, security light won’t go away. I undid the harness made sure I didn’t bend any of the prongs. But no change. Maybe I damaged the harness? Post owner was smoker All the wires are nice yellow tan

Hace you seen the trip counter not work not count the miles used?

Como se conectaría ese cluster de silverado 1999 a una 1992

Is there a schematic available for these clusters?

I have a 2000 Chevy silverado 1500 and the gas guage, trans temp, gear selector, mileage and the message center has a battery light on and they don’t work but everything else does how would I fix all of that

Great video. TLDR of the video... about 80% of cluster issues with the 99-02 is not a cluster at all!

01 cluster prnd an odo doesn’t light up message center doesn’t come an most warning lights not on besides for blinkers they work an gauges work

Is it possible that the cluster has more than one ground?

Replaced my 02 cluster with a 7 gauge do you reprogram the mileage

What if my gas gauge is pointed straight down and it goes on/ off while driving then throws battery and security light. Also oil is a bit shaky

02 2500HD. Trans Temp, Eng temp and fuel drop out message center battery and sec 4wdas well as abs light. Press the brake pedal and it comes back. Release the brake and it drops out again after few seconds. It’s the craziest thing. Can send video if needed. Thoughts?

Si se podria

Como los conectas asi para que Que encienda

Where are you located at

Hey man , I think I messed my shit up. Lol. 😭 How do I go about sending you my cluster ?

Hey do you have a email or a telephone number I have a cluster that I would like you to repair. Would like to find out a price and availability. Thank you

So nothing works on my cluster then I plug in scan tool and everything works I'm thinking a bad ground what would you think
