CONNECTOR TERMINAL REPAIR FOR GM INSTRUMENT CLUSTER BY CLUSTER FIX

[@johnnycochringesq5525]

You reinforced my suspicion that my cluster was wacko because of a loose pin and gave me instructions to fix it. Thanks! It now works without issue. A6 was the loose connector btw

[@matthutton3598]

Oh man I have been chasing this problem for a week and found this video and in 15 min problem solved. Absolutely great video thanks a bunch!!

[@Beavis4pres]

Thank you. 04 GMC Sierra, have been doing the "Fonzie" for a long time. I was 15 minutes from chopping and splicing in a new connector when I saw this. Problem solved.

[@greg687]

I was all prepared to put in a new cluster, but your description of the symptoms was exactly what I had, so I tightened up the entire top row of wires and for two days now the cluster has worked like it should. Thank you!

[@trevormckeehen2010]

This is an extremely helpful video. You should reshoot it just for better video. I think a new cell phone would offer better video quality and help us see better what you are trying to show us on the small pins. Thank you for the video.

[@superred13]

Excellent video man, I've been battling this damn cluster for years luckily I ran across this video, Thanks I knew it was something simple.....

[@artyart31]

Thank you sir for this. My check engine light would intermittently go off. I would push /tap on the cluster and it would come on. First I thought the bulb but after inspecting it was well solder. I d pinned squeezed the terminal together and not it’s working. Thank you again

[@danielsklut2912]

I did the lights and stepper motors and then the cluster started working intermittently. Wiggling the plug would cause it to function some times. I found this video and got the ground pin out using a sharp pick and crimped it with needle nose pliers. That helped. I had trouble with the other pins so I did a little checking for a pin removal tool. I found this set by Lisle, the 57750 Wire Terminal Tool Kit for about $35 on Amazon. I ordered the set and will do them all when I get it.

[@alejandroamado4232]

Thanks a lot. I did this with my ground wire back of my cluster cause when I moved the wire all my gauges turns off with the odometer. I did all your steps and now everything works.

[@flunder203]

you are excellent. you have saved me money and offered a solid troubleshoot. thanks!

[@freddieidderf]

Success!! Thank you for the video! FYI I just bought an 03 2500 and the backlight was working but nothing else, after tightening up the 3 terminals she's fully functioning, AND as a bonus I discovered the truck only has 148000k on it!!

[@kaprahm]

thats what it had when the cluster stopped working.......it won't record mileage without power

[@linomedinachinchon3071]

same!. My car didn´t record mileage for 2 years :)

[@FluffyMI6]

Hopefully this works for me, I had a problem with my cluster not powering on at all but as soon as I moved the harness it turned on. Very helpful, thank you!

[@chrispatterson4685]

Just replaced all the stepper motors and installed blue LEDs using a kit sold on Amazon. Last person who tried burned up several of the solder points...worst of which was the speedometer. Luckily, I used to modify Xbox 360 consoles back in the day (Reset Glitch Hack), so I used my fiberglass pen to remove the epoxy on the mobo to expose and solder to the trace(s). After all that, I plug in the cluster and nothing...then I wiggle the plug on the back and the stepper motors wind up and the leds come on. Looks like I'll be working on the plug tonight. Thanks for the video!

[@bonevillessei]

thank you so much for this post and the details. i did try and fix them before watching this and messed it up and realized that i put the one wire into b8 not b9 and that fixed my problem

[@alexisnunez6239]

Hi i have a 2002 cadillac escalade and my whole dash flickers, and the gas needle goes down. This only happens when its hot outside, I don't have this problem in the winter but throughout the year I do. what do you think the problem is ?

[@NickF6.6]

Yeah I just had my cluster rebuilt and found out the crappy way my old cluster was good… what’s the chances of me using a pick and just slightly bending the terminal over instead of completely depinning?

[@jcbbe]

you are a good man, you know your stuff

[@tcameron5538]

If you have an "03" Tahoe with back lights but no gauges or DIC you say it is an internal cluster problem. Mine I can squeeze the plastic around the connector and the gauges will come on. What is the fix for that, or is there even a simple answer for that?

[@joshuafimple4069]

T Cameron did you ever figure out the answer? I have an 03 Avalanche that does the same thing. I can move it around and if i squeeze the grey and blue parts on the clip, get the entire thing to come on and function fine until I shut it off and leave it for 15 minutes. Then its off again.

[@ZooDudeYT]

Same problem here on an 04 Silverado 1500. Did you guys replace your clusters?

[@chrispatterson4685]

Same here. 2003 GMC Sierra Denali...I replaced all the stepper motors, replaced leds, went over the solders on the resistors and even reflowed around the pin connector. I have already confirmed the power and ground connections for the connector seem to be in good shape (removed them and made sure they were shaped correctly, etc.) When I plug in my cluster, I hear the stepper motors wind up. So when I turn the key everything comes on. Everytime I think I have it fixed, i put it all back together and in a few days it won't work. Each time all the leds work, but the PRNDL, gauges, nor DIC come on. So i take it back out then plug it back in and it works. I have questioned my solders multiple times, I have questioned the connector multiple times. Yesterday I pulled it out again, went over my solders again then plugged the board in. Everything came on...then I moved the board putting a little tension on the wires and connection and I noticed one of the amber leds (check engine maybe?) started cutting out. Moved it back and it comes back on...so, I'm back to thinking it's the connector. I'm honestly about ready to pull that whole connector out and replace it or refurb it. Has anyone else pulled it out? What did you guys do to get yours fixed?

[@thurgoodstubbs9670]

@@joshuafimple4069 yep, that’s what mine is doing. Did you ever solve this issue?

[@thurgoodstubbs9670]

@@chrispatterson4685 that’s what I’d like to do. Replace the female connector that goes through the firewall and all the wires. That thing is so short it’s a bitch to do such delicate pin removal. How did you do on your project?

Thanks for the video , my1999 Silverado sometimes while driving it shuts off and the info center comes in with the battery red sign , then I hit the steering wheel and it comes back on , I'm gonna check because it seems as this video may be the solution for the problem , but in case is not I'll definitely send you the dashboard so you can further assist, thank you for the video you do t have o share this but you do , that says a lot of you guys, much respect.!

[@keetonhubbard1484]

What if my lights come on and my needles don’t work, but I wiggle it enough the needles will work for a little, does that mean anything? Mines a 2004

[@BurgundyChuckz145]

The issue I'm having is the fuel and coolant temp gauge wasnt working, nor was the PRNDL display, so I replaced the cluster with a rebuilt one, and I'm having the exact same issue, what I noticed is the display will illuminate with the ignition in the ACC position, but not the ON position

[@ericmorales2272]

My backlights, mileage, speedometer, RPMs all work. All My other gauges fuel, temp, battery don’t move. And all the brake light, battery light, Check engine light are on. My cluster is lit up like a Christmas tree except a couple gauges aren’t functioning. From your explanation that’s a cluster issue?

[@charleslarrimore6521]

On a 2003 silver Chevy Silverado what wire at the pigtail operates the instrument cluster back lights

[@robtemple3445]

I realize this is an old posting, but the back-light dimming ckt, is A11 on this year/model. The backlight ground is A12. HTH! RT

[@LandenBMS]

I have an 03 Sierra, I have adjusted the pink, orange, blk w/white and the black wire next to it. The backlights still won't stay lit. is there another terminal I should adjust or could this be some broken strands in one of the wires?

[@awidowswayaftertheloss2273]

Thank you soooooooooooo much!!!

[@georgeperez4770]

Will this help if the PRND21 are not lighting up as it should? Everything else is working fine.

[@ClusterFixWashington]

+George Perez What you are experiencing is an internal cluster issue that needs repaired

[@Unknown-vm8ri]

U forgot 3

[@Unknown-vm8ri]

George Perez my does the same thing but it turns on but when I hit a speed bump it turns off

[@FluffyMI6]

If you want to fix it yourself, it's usually a bad soldering joint on the resistors inside the cluster. Forewarning: if you're not very experienced in micro-soldering, It might be best to take it to a computer/ tech shop that repairs motherboards and have them do it. I fixed this same problem in my truck but I wasn't well equipped enough to do the soldering properly and the solder joints look like a toddler tried doing it... but the PRND31 is on now!

[@docbrown7572]

When you re wire the pig tail how do you know which wires of the same colors should go together that’s my problem

Will this work for the PRND321 indicator/ odometer and message center occasionally flickering on vibrations? When moving the rear plug they turn on and off together. never one at a time. 1999 silverado

[@darinclark7558]

Seems I’m almost there, just bought a new cluster(cluster wasn’t the problem). Everything works except for the speedometer would It be the a4 or could It be a ground issue or how can I tell. 06 GMC Sierra 1500 Any help would be apreciated

[@ClusterFixWashington]

Most likely an internal cluster issue since this video is for problems that the 99 - 02 models experience with a different type of cluster

[@fredc8346]

I know I have problems with the cluster for speedo stepper and some lights, so i will have to do those some time, but recently a couple times all of my gauges and odo etc died. Came on later, but now it appears it is dead until I fix the problem. This sounds like what I may have.

[@jakewortman6653]

how do you fix these terminals without being able to cut the harness out first as you have done here. Not much slack to work with. Will electronic spray cleaner help any with the intermittent connectivity issue?

[@thurgoodstubbs9670]

Hey Jake, did you ever get your questions answered. I have the same thoughts.

[@BostonBorn]

My 2004 Escalade instrument panel has been dead for a couple years. The one thing that does work is the check engine light (when something needs fixing). One odd thing though...the signal lights stay on 100% of the time whether the truck is on or not (they stay lit even when there's no key and all locked up), the directionals still work despite this issue. I also have no odometer lights (no idea what the actual mileage is...) or any audible indicators, such as the back up sensor (I rely on the blinking light in the rear of the truck...😳). All that being said, it sounds like it's a power issue or lack there of. I will be implementing this fix.....what's the worst that can happen??? p.s. Yes, I will disconnect the battery first 👍🏼

[@ClusterFixWashington]

That sounds like an internal cluster power supply failure which is generally repairable and is also part of the Full Rebuild service found on our website.

[@thurgoodstubbs9670]

@@ClusterFixWashington if I had you do a rebuild of the cluster and the problem is the 3 wires on the stationary harness it seems it would be better to do the fix shown in the video. What say you.

What that tool called that push wire out? I am deaf. It was difficult to understand what were you saying. Would be great if anyone tell me what kind of tool was it. So I can order one to fix mine mine little loose in 03 Yukon

[@jessematson3285]

Terminal removal tool. You can use any small pin or maybe a paper clip if you are careful. You just need something to push the little tab on the terminal to side so the terminal can pull out from the retainer inside.

[@ericmuldrew4630]

I have a 2003 suburban and the cluster has no power sometimes but sometimes it comes on, I was wondering what my could be?

+eric muldrew What you are experiencing is a common problem with the internal power supply circuit that is need of repair inside the cluster itself

Hi I have a 2004 avalanche the speedometer was stolen and all the wires were cut. I installed another cluster and connected the wires that had the same color.

Anybody looking for Silverado instrument cluster plug repair this is your video. But it barely pops up when you search that 😅

[@peterjohnson9822]

Lets say we need a new terminal. Do you have a part number for the terminal alone. I can find the connector for 2004 is 12110088 but I cannot find the terminal part number.

[@robtemple3445]

This may be a little late, but using the P/N you provided for the connector shell, I found the terminals you were inquiring about. There are two sizes. The first is for larger wire diameters (0.8-1.0mm/18-20ga): p/n 12146448. The 2nd p/n is:12146447, which is for wire size 0.35-0.5mm/24-26ga. I actually found them on the "mouser.com" website after Googleing the p/n you provided. They are called "Series: Micro-pack 100". Manufactured by Aptiv (formerly Delphi). Thanks for the connector p/n, I've been looking for these for a while. I'm going to make a test bench for my instrument cluster (2003 GMC Envoy) .

Professional tool trucks sell specialty tools but you can also use a stiff pin to get the job done.

[@ClusterFixWashington]

Maybe it is dragging on the gauge face because the needle was pressed down too far?

I have a 2003 chevy silverado 1500 side step. I have already repaired my cluster and it worked for a good minute and everything was great!. Until the needles and gauges stop working and the PRNDL and display not working again. The ONLY thing working at this point are my blinker indicators and the backlight on the cluster. I'm thinking at this point is the harness connection. 😫🤷🏻‍♂️. If anyone else having the same problem and they found an answer. Please share. I'll take any help at this point. I really don't want to buy a new cluster but if all fails. Then I don't have another choice.

[@soxrox00]

Did you ever figure out what was going on? Having this same issue right now.

2003 and later models don't experience the connector issue for the most part, it is an internal power supply issue or other board problem that we see on a regular basis
