Door locks won't unlock

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

Hello,

It looks like you have a BCM that is going out because it controls all of the doors but to be sure lets check the fuses that run the system.

If the fuses are good then you will need to get the new BCM programmed by a shop.

Here is the BCM location and the fuse panel diagrams

Check out the diagrams (Below)

Please run this test and get back to us.

Cheers, Ken
