Rear power locks mysteriously stopped working

[scjmc]

Hasy anyone else seen this? I searched but turned up nothing. A couple of months ago both of my back doors would no longer lock/unlock with the power locks. I cant hear the actuators even trying. This leads me to believe that the BCM is not telling them activate, but I really have no idea. This is a problem because I am accidentially leaving one of my back doors unlocked on occasion.

The LS doesn't have a BCM (Body Control Module). Instead it has a FEM (Front Electronics Module) and a REM (Rear Electronics Module). It is the REM that controls the rear door locks (and several other things). I'd start by checking the connectors at the REM. (It's in the trunk.)

ill check that out. Does anybody know what else the rem controls?

While in the trunk check the fuses.

Rear windows, fuel pump, all rear exterior lights, trunk release, fuel door release, rear window defrost grid, trunk ajar switch, front passenger door lock, rear door locks, front passenger door lock switch, trunk light, fuel level senders, radio antenna booster.

Thanks for that info!! I have gotten some sort of flu over the weekend and have not had a chance to look at it again. I hopefully will feel better tomorow.
