I'm at a loss... I can usually fix most things on my vehicles, but this one's got me stuck.
Okay, about a month ago, the LED's (odometer/Radio) in my 02 Tahoe started flickering, and on occasion the idle would dip below normal, almost to a stall. Most of the time, I could turn the truck off and start it again, then it would be normal.
Then, on Wednesday, I went out to the truck, tried to start it, and absolutely nothing. No dome lights, nothing.
The battery is fine, the alternator is fine. I can't even hook a code box up to it and get an error code because there is apparently no current moving.
Does this sound like anything to anyone? Some sort of sensor, or wiring harness issue? I've tightened any harness that I could reach, including battery cables. Relay?
