We have a 2006 Pontiac grand prix with power door lock problems it started with the rear drivers side door not unlocking then the passenger rear door not unlocking then a few weeks later the passenger front door not unlocking. They won’t unlock with either the remote key unlock button or the unlock button on the doors. The doors will lock correctly. I find it hard to believe the lock actuators in three doors went bad. Any ideas where to start? Thank you Bryan
The way it happened slowly I wouldnt be suprized if the actuators just didnt die off one by one. The newer actuators dont seem to last as long as the older ones. Your going to have to remove the door panel and see if its getting the signal to unlock. If it is then bad actuator.
