Power door lock issue
Hello, all. I'm having an issue with the power door locks on the driver side of my '05 Screw. Here are the symptoms:
Since I can lock and unlock using the passenger switch and the RKE, I'm assuming the actuators are good. Could it be a pinched wire somewhere from the driver side door?
Any help would be greatly appreciated.
- I can lock all the doors with the driver side switch, but cannot unlock anything. When I push the switch nothing happens. No click, nada.
- I can lock and unlock all four doors using the the passenger side switch.
- I can lock and unlock all four doors using the RKE.
- I took the switch from the driver side and hooked it up on the passenger side and was able to lock and unlock all four doors.
- When I took the switch from the passenger side over the the driver side, I'm back where I started being able to lock but not unlock.

The PDL ( with the factory RKE system ) signal the VSM with a ground signal on either the lock or unlock inputs for the VSM to know what to do.
It could be a wire in the door to a-pillar ( unlock is the pink w/ light green stripe wire ) or in the driver's side door sill.
If you want a quick test on the door to a-pillar, you can pull the passenger side door lock switch, and meter from the pink w/ light green stripe wire in the connector to ground.
When the switch is at rest ( not being pressed either way ) the pink w/ light green stripe wire to ground should show an open. When you press the unlock on the switch, the passenger side pink w/ light green stripe wire should show continuity or a low resistance path to ground.
This would tell straight away if the switch to the common splice on the passenger side ( the working side ) is working or not.
I would assume the connector on the VSM ( Vehicle Security Module ) is good, considering the input from the passenger side switch ( same input as the driver's side ) is working correctly.
If the meter shows an open with the driver's side switch being pressed you can reverse the test ( check for continuity on the driver's side when pressing unlock on the passenger side ) to verify this.
I would go looking for the pink w/ light green stripe wire wire to be broken in the rubber channel between the door and the a-pillar 1st, but that is just my thought.

Man you are good! I went in there today, and sure enough the pink and green wire was cut in two! I patched it up and voila! Doors open!
Next time you're in Pitman, you can come on over for a beer and a cigar.

Thank you for the offer, I'll keep it in mind next time I am in NJ.
Glad to hear it was a fairly easy fix, and the other members that have the same symptoms will appreciate the picture and info. Thank you for the follow up with the solution to the issue.
