What would make the automatic doors on a 1999 chev venture lock and unlock as you are driving along?
Gremlins or poltergeists. Or maybe an angry teenager.
There must be a short in the wiring someplace. I would be very careful these things tend to catch on fire.
Have the power control module checked, it sometimes gets broken or loose connections in wiring.
Do you have one of those key chain fobs that will lock/unlock your doors? Maybe that is bumping against something while you are driving. Either that or your kids are playing with the buttons!!
More than likely it is a wire that has rubbed on something and the insulation is damaged causing a short, and activating the locks. The most probable location of the problem is the connection from the drivers door the car body. The wiring for the windows and locks is routed through a rubber conduit between the door and body. It could be any of the doors but the drivers door gets the most use, so that's a good shot. Good luck! ps. No fire hazard. The fuse will blow first.
