Hey everyone, yesterday I tested everything to try find out the causes of the electrical issue iam having.
The door controls for the driver doesn’t work. When lock and unlock the car either by fob or from the passenger door control (passenger and other doors the controls work, passenger lock and unlock and window roll down and up, passenger seat buttons also work)
The drivers seat feels like stuck, is not going forward or backwards neither going up, but it makes weird noise and does go down a little but them stop. Act like if battery in the car was weak, is not.
Anytime i lock and unlock with fob, the driver door doesn’t respond. Also consequently the power mirrors doesn’t work.
I tested the switch control buttons at the door, and it seems working fine. I also checked some of the plugs going to this switch and power is going in one of the wires. When i tested the fuses on the left side of dash all fuses work. But at same time seems like all the fuses not receiving energy even when car is running or key in on position. I tested the wires going to the fuse panel and has energy going through but seems like the fuse panel itself not transferring energy?.
I don’t know know what to do anymore. I checked fuses at the engine bay and seems all working. Just not sure the relays. Maybe i will test the relays for click and if energy pass through them when clicks.
It’s a 2012 tahoe ppv 2wd, police trim when check on vin number. Got in auction cheap due to this issue. I need help from your guys more knowledgeable about ppvs.
There’s is some wires loose right at the middle lower portion of the dash. I don’t know what those wires were used for. Maybe for the center console? For police equipment? But is a lot of wires. Only one of these wires is hot, and 3 more only that permits energy cicle through. Other wires dead.

wrong section @Fless @07Burb
and for the OP unless you have had the battery load tested, no telling but the battery and battery cables/grounds is always the 1st place to start as ground zero.
