I had my cluster for my 03 sierra repaired about a year ago (normal stepper motor issues and dim gear selector) when I got the truck, so im not sure if it already had an issue when I got it, but the gauges will intermittently not work when I start the truck, but if I unplug and plug the cluster back in, they'll start again. Same thing happens if I pull and replace the ipc/dic fuse under the hood(ive tried swapping fuses, new fuse, cleaning contacts, etc.) I made sure the contacts on the back of the cluster were clean as well, and the wires as far as i can see look to be in good shape. Both ground wires and both power wires have good connection. Could it be an issue with the back or something? Ive been driving it for the past year with the dash bezel off and unplugging the cluster to get it to work every time it doesn't. Once it's working, it never shuts back off until I shut the truck off. Nothing works except the backlight, turn signals, and check engine light when it happens. I just sent the cluster back to the guy that fixed it to check it over, and he found no issues with it. Dont know where to go from here, anybody ever deal with this issue?
