'04 venture auto door lock problems

[andt]

Hello all,

I have a 2004 venture LT. A couple days ago the door locks began to randomly and repeatedly try to lock and unlock. It seems to occur mostly around 30-35mph. The lock and unlock buttons on both key-less remotes do not work; however, both power door buttons on both remotes do work. The lock/unlock buttons on the doors work, and the all the actuators are working. The fuses all look ok. I turned off the automatic lock/unlock program feature, and while the doors now do not lock and unlock when shifted out of or into park, the problem still remains.

I'd appreciate any suggestions, before I start to take things apart.

Thanks.
