Greetings, y’all!

My buddy’s got an 04 Chevy Colorado with a dead instrument cluster. All other functions of the truck appear to be operational. Mileage unknown, for obvious reasons. It’s a four-cylinder but we can’t remember what size it is. Battery is good, connections are good, grounds appear to be good, fuse is good.

I was curious if anyone would mind looking up the wiring diagram for this cluster so I can check its inputs to make sure it’s getting all the power and grounds that it needs to, maybe a diagnostic flow chart or technical service bulletins. Any other non-generic, vehicle specific thoughts would be helpful. Thanks!

Fred

edited to add; if anybody can tell me where this instrument cluster‘s ground locations are, that would be very helpful in the event that I can get to them without tearing the dash apart. Thanks!

Sometimes just plugging in and unplugging the cluster a few times makes the connections work--but most likely you'll need to send it off to the online cluster repair guys- just google a few specialists. That connection is made when the cluster is fully seated, perhaps vibration etc has made it quit. Did it die all at once or was there any intermittents going on?

It was sudden. Worked when it was parked one day, dead the next time it was started.

I will tell him that so he can give it a shot, but still would like to get pin outs, ground locations, and any applicable TSBs if possible. Thanks!

Yes, I am quite aware of all data, but I’m trying to repair this without unnecessarily spending a bunch of my buddy’s elderly moms money. If it used to be that we could get good information from people more experience than us here. Maybe I should be asking this question in the mechanics lounge.

I hope you all are having a good weekend! If anybody has any ideas, please let me know.

Welcome back Fred it has been a long time since we heard from you. BAT has changed drastically since youtube and online quickie fixes. We are down to bare bones staffing now

Did you try the global reset? Disconnect both battery cables and touch the ends together for a few seconds,
( I'm not sure of the exact time)
