Hey everybody. I am new to this forum and looking to get some help with my 2004 Chevy Z71. At the end of summer I hopped in my truck to find the message center below the gear selection indicator was half ways on. This was with the ignition off. I proceeded to crank the truck but the gauges never came on. The only thing that worked were the back lights, the turn signals, and the check engine light remained on (go figure). As never having this problem before, the first thing I did was check the fuses but that did nothing. Well after running out of simple fixes I left it alone and figured I would just have to deal with it at another time. I drove it for about a week with no gauges and one day after work it decided to come back on. Drove home and one other place that evening with everything working perfectly. The next morning nothing again. It sometimes will work for a couple of weeks straight with no issues then will not work for a couple of weeks as it is now. I know it also seems to work the the air is drier and seems to mess up after a rain or a damp morning which may just be just be a chance happening. I have not had much time to mess with it because of school and work but now that school is done I have time and need to try to figure it out. This is what I have done: Checked fuses, checked the 2 grounds below the driver door (not sure which one is for what or if there are any additional grounds). I have also pulled the cluster out and put a test light on the wiring connector that goes into the instrument. When I did this the only wires that were getting power were the blinkers, back lights and the check engine light (which are the only things that work all the time). Although I do not have a wiring diagram I assume these were the wires that were hot because the light blinked on and off for the blinker and the light on the test light dimmed as I dimmed the the lights. I have taken it to one mechanic who seemed very knowledgeable but he seemed to think it was in the instrument cluster but I am not so convinced since it does not seem to be getting power to the cluster. He also said when he hooked the computer to it the the gauge cluster was not receiving a signal (which I thought would mean that the problem is not in the cluster). I cannot afford to take it to the Chevrolet dealer right now so I am just wondering if anybody has any idea on what the problem could be?? One additional piece of information is that I know the cluster has been rebuilt (I assume for the stepper motors) as it has a re-manufacture sticker on the back. I am sorry for such a wordy post just trying to put all the information in. I am not a mechanic but do have some mechanical experience. If anybody has any ideas please let me know. Thanks!
