Power doorlocks lock/unlock constantly

[BeefaRu]

All doors but driver are lock/unlocking constantly when the battery is hooked up.

 

Disconnecting the drivers "sender" wire cuts the signal and all the doors stop.

 

Anyone have a clue? Doesn't matter if driver door is open or closed, or whether it's locked or unlocked. The second the battery is hooked up and I plug in the electric lock on the drivers door it starts happening.

 

We changed the rear gate to loyale and are using the loyale harness. Its newer than the 88 rear gate harness. I'll change that back today and check back here tonight.

 

Any insights are very badly needed. Thanks! --E

i'd check the wiring in the drivers side door. has it ever been in an accident around that door area or the door been removed?

 

where the wiring passes through the door and into the car it could be cut/shorted/exposed due to the tight bend and possible sharp metal curves around the door jamb.

 

or replace the drivers side switch, it may be bad.

 

could probably test the wires with a voltmeter for a short/continuity.

Thanks for the input! We figured it out today. The driver's lock solenoid sends the commands for all locks. I was guessing it was that, but my friend wanted to troubleshoot everything else to be sure.

 

After 3.5 hours, we ended up getting the part for $3 at a junkyard 10 minutes away.

 

Thanks again, and now this particular problem has a solution on the forum.

we should have the thread moved over to the USRM, or maybe someone could do a quick write-up on how the system is laid out and how this problem could occur......

on a similar note, in a car I used to own, locking the drivers side lock would lock all the other doors, but the passenger side would occasionally unlock itself.

 

some liberal application of PB Blaster (lubricant) to the whole door lock/latch mechanism fixed that problem.
