2003 GMC Sierra 2500HD Dash Cluster Problem
So I have researched everywhere and I just do not know what to do. My dash cluster in my 2003 GMC Sierra 2500 just isn't working entirely. The directional arrows work, the check engine light will come on, however the digital odometer, the tackometer, speedometer, temperature gagues, and fuel gages do not work...pretty much anything with a needle plus the odometer. I took it to a GM dealer a few months ago and footed the bill to have them put a brand new cluster in, however it also didn't work so I had them take it out and put the old one back in so that I didn't have to pay the $400 or $500 for the new one they had just put in. Oddly enough sometimes the whole thing will just pop on and work, however it is happening less and less frequently. The odometer does not track mileage when it is not on either. I have taken the dash cluster out myself a few times to try and check the wiring and connections which all appear to be ok, and generally speaking as soon as I start taking it out it will turn on, again, more recently this hasn't been happening. I mentioned to a mechanic that I know that I thought there might be a short in one of the wires but he told me that would be almost impossible as the wires stay stationary almost all of the time, and aren't moved around or bent a lot. The mechanic at the GMC dealer was no help at all, he told me that it would cost thousands of dollars to come to the bottom of what is wrong and that I would be better off buying a different truck. I would really love to get this fixed but I am losing hope that it can be. I have considered selling the truck but that is a little difficult without a working dash cluster. Some people keep mentioning to me that I should replace some sensor but I can't find information anywhere that there is any sort of sensor in this vehicle to be replaced. If anyone has any information that could help me get this fixed I would greatly appreciate it. Thanks for reading my novel!
