Chevy Silverado

I have a crew cab 4x4 half ton silverado with 5.3 engine. Both of the rear door locks have stopped working with the remote or with the lock switch on the driver door. I can operate them manually only. Any ideas?

Since neither the remote nor the door switch do anything then you’re just going to have to start with the wiring back there. A wiring diagram will be handy (Autozone’s online repair info may have them). Since its both the rear doors I’d start by finding whatever wire feeds the power back there.

Did they stop working at the same time or at two different times? If one went bad then the other I would say you need a pair of door lock acuators.

The car was parked in the garage for a while and when I went to use it neither door worked. I would say they both stopped at the same time.
