Battery drain
2004 GMC Sierra 68644 miles
I have an intermittent battery drain. I have not been able to locate. I don’t drive the truck but once or twice weekly. Randomly I will attempt to start it and the battery will be dead. I have done parasitic draw test and it will pull as much as 2 milliamperes. I have pulled every fuse and unhooked the alternator and still have the drain. I am at a loss on where to look now. Any help would be appreciated.

Do either of your trucks have a security system? Mine does and if u try to open a door when its locked the system throws a light. The light stays on and drains power until your disconnect the ground.

Gauge Cluster, Air Condition Switch Fail 
Solved
2007 GMC Sierra Classic / Duramax / 3500 327000 miles
The speedometer and RPM function normally. The indicating instruments are “zeroed”, not indicating anything. The battery discharge light is illuminated though charging system is actually functioning normally. Whether coincidence or not (I think NOT) the air conditioning on-off switch stopped working also. This is not steppers as my 43 years as an airplane mechanic rule out a coincidental failure of 5-6 stepper motors at the same instant. I’m thinking ground, body module. If it’s a fuse I can’t find it…

Best answer (according to Jigsaw)
Mahmoud, Thank you for answering! I also was chasing a fault in the CAN buss. I actually solved the issue. The technical data identified an in harness gang ground in the dash wiring behind the radio. That is why such unrelated systems were affected.
@JigsawI know this is 3 years old, but I’m having the same exact issue in my 2004 Duramax. I’ve had since ‘08 no issues. Can you point me to the technical data sheet for this?

Also passenger tail light intermittently works
Redrover have you ever experienced a General Motors ground fault in gang to chassis grounds? Bizarre doesn't begin to describe. I stumbled across a Youtube guy in New York that took in a 7 month old GM pickup that : dealers in contact with the factory failed to fix. Horn honk with door close, wiper switch energized brake lights... he found the problem in 2 hours, a ground behind the right front fender liner. GM paid for the troubleshoot and repair. All the best dude! Good luck and good grounds
CommentRadio won’t turn on

Went on vacation, battery died had to jump start, now radio won’t turn on. Looking for the radio fuse location or what it is labeled as, NOT the location of the fuse boxes.
