2005 Buick Terraza Question: Unlock doors & liftgate

 

Question

Visitor, Xenia, OH, April 16, 2010, 07:11

My doors, sliding doors and liftgate work perfectly probably 80% of the time, such as when you shift to drive, the doors lock and when you shift to park, they unlock.
When the above doesn't occur, only the driver side lock works by either the door lock switch and the remote, but the other doors will not work. I can drive 10 miles and they again work perfectly. This is a real problem when you need to unload cargo and the liftdoor doesn't work. I might guess that the system needs reprogramming, but I don't have the proceedure to do it.

    it is possiable you need to clean contacts in door. They are easy to reach and just clean with light sandpaper.
