Rear door ajar draining battery

[Philion]

2014 Silverado 1500, having issues with rear door ajar, staying on draining battery also rear window will only go down to open if a back door opens both back windows go down not pressing switches but switches won’t work if the doors are shut. Any solution to fix this problem?

sounds like some wires are broken/insulation worn through in the wiring harness, probably in the door jam area.

I agree with Dave, you probably have broken wires in the wire harness at the door. My 2014 had a issue on the drivers rear door where there was 1 broken wire in the rubber conduit that runs between the B pillar and the door and it was not unlocking/locking the door at all. I repaired the wire and all was good again.

 

You will need to remove the B pillar trim and pull the wire harness from there and pull the door panel and pull the door harness through to the inside of the door and investigate it. Mine had a random break and had corrosion on the wire that broke open so it was damaged for awhile before finally breaking off.
