Electric door locks 2004 Chevy Venture

I would try a replacement used lock/unlock switch panel before anything else,it would cost almost nothing used and usually fixes this problem,and the switch panel pops out easily for replacement Next possibility would be a broken wire where the wires flex at the door hinge area.Grab one wire at a time and pull firmly until you find a broken one. Make sure the replacement switch panel is a known working one.

I don't have a solution, but a related problem. Our 2004 Chevy Venture power door locks are cycling (locking/unlocking) on their own while we are driving. This coincides with our remote keyless entry losing its effectiveness. I tried replacing the battery on the remote, but to no avail.

look for childrens safety locks around the latches also if is poered make sur all safty locks are unlock on drivers side

It sounds like you've got a broken wire on the drivers side door. Usually this occurs at the flex point of the wiring harness. Peel back the outer covering carefully exposing the wires inside. Repair any broken or those about to break. Solder & retape or shrink rap with heat gun.Hope this helps. Good luck!

check the system fuse and or circuit breaker. check the switch wires for damage and loose connections. check the switches for continuity. remove the door panel(s) and check the actuator wiring connections to see if they're loose or damaged. inspect the actuator rods if equipped to make sure they arn't bent or damaged or loose connections. the actuator can ce momentarily. a discernible click indicates that the solenoid is operating properly.

open the door and look on the side of door for little switch up and down ,it a safety switch ,little gray lever sticking out on the side of doors, move it up or down ,read decal on the door jam,hope to help robert b.

That's one of those thing you will need to look at. check the electric solenoid to make sure it has a good ground and "hot" connection. Also make sure that the lock mechanism is operating freely and not binding.

the passenger door switch pack controls all door locks as this is the receiver from the remote you might want to try this and also check connections

check for an open door ( all doors ) , defective courtesy light door switch, or short in interior light electrical circuitry.

sounds like a faulty lock/unlock switch, Does the other front door lock switch work properly ?
