2005 Uplander LS with about 70k. The power door locks continue to unlock while driving at random. Even parked. It seems to be related to vibration but I can't be sure. The locks will lock automatically on acceleration from a stop or with the dor switches, but then typically the drivers door will unlock followed by the rest as though the remote is being used. The battery was removed the the keyless remote and there isn't even one near it. I unplugged both front door lock switches but the problem persists. Ideas? I also noticed today the radio sounds would not come on although the display showed it was on and working.

May be a problem with the Body Control Module ( BCM ).

I'll talk to a dealer today. I did notice the locks seemed to cycle when the drivers door was swung open about half way. I tried to maneuver the cable around coming out of the door to the body in the event something is shorting. It seemed to resolve it, but I haven't driven it since. Thanks for the tip on the BCM.

Got the problem figured out. There were some worn wires under the carpet by the drivers heel area grounding or shorting. I have to wonder how many other problems are caused by these shorts taking out some of the electronics. To recap, I had issues with the radio turned on but no sound, but mostly the locks cycling as if the button on the remote was being pushed. I noticed the problem seemed to apepar with vibration or opening and closing the drivers door. Everything is fine now.
