Can’t seem to find a similar issue to mine anywhere, a few of my gauges get stuck in particular the volts is always the first one, but could be gas gauge or any other gauge except tack and speedo. No codes, have tried to pull them several times. have checked ground strap under hood looked through a few fuses and taped a black wire that was rubbed through. The DIC and shift indicators go out and that’s when they start to stick and will eventually max out unless DIC and shift indicator turns back on. Once it does they still don’t zero out but don’t get stuck any farther. The shop that rebuilt my cluster is saying that it has to be a wiring issue because it’s the same issue I came to him to fix then started up again 3 days after repair. one day it had a loss of power seemed like trans was confused and then “popped” back into first and didn’t sound pleasant. But has only done that once. Have no clue what it could be GM was no help at all. If I disconnect the batteries and reset it , it’ll act fine until it’s next episode of bs. Hoping someone has gone through this and can point me in the right direction, bought the truck a 2 weeks ago and didn’t start this until last Friday. Has tbc fault and park sensor and tpms light on DIC. Has aftermarket head unit speakers and amp steps if that could have something to do with it. Tested the alternator at oreillys and it tested good but shows it’s age under the hood. Also believe i have the factory batteries in it but no slow crank and no drainage of them. Has gotten a lot worse since the dude supposedly “fixed” my dash just at a loss. Don’t want to point fingers but could the cluster still just be bad and the shop didn’t fix it properly?
