Rear doors won't power lock
I have an 2008 HHR LS and I recently changed my rear doors and passenger door with a 2007 LT. When I hit the power lock the front doors work fine but the rear locks won't work. I know the LT and LS driver side door electrical connectors are different but the other doors were the same. I am guessing I have to change out the rear door wire harnesses to get the rear power locks to work. But I am not for sure if that is the issue.
Do anyone know what the problem is?

thanks for the reply. So I'm guessing if the front doors work then the rear should also. Basically either something electrical or power locks are messed up with only the rear doors. If the wire connectors are the same then it's probably not that.

I just find it weird that only the 2 rear doors do not work. the front passenger door works. The car I took the doors from was in good shape better than my car but it had a bad engine. so I don't think anything was wrong with the doors themselves. I guess I have to take off the panels and look for myself. I've been busy recently... so will get to it soon.

Did you look at the schematic?
First question is: do they power UNLOCK?
Second question: is it BOTH front door buttons?
Third question: what about the fob?
Fourth question: what about auto lock; Locking the driver door then closing it.
Fifth question what about auto lock/unlock: when you move the shifter in and out of park. Setting in the DIC.
If you need a Owner Manual see the link in my sig.

The rear doors:
1) both front door power lock buttons do not lock/unlock the rear doors.
2) The fob does not lock/unlock them
3) auto lock does not lock them
4) moving the shifter in park or drive does not lock/unlock them.
Its like they are not connected at all. That's why I was thinking maybe the individual connector pins were arranged differently (between the 2007LT and 2008LS models).

If panel are the doors without windows then no. The doors look exactly the same. I got them off a 2007 LT but I don't know if they were actually 2007 LT doors. The owner could have changed them out with something else.
