Well, my power door locks randomly stopped working. Neither the key fob nor the buttons on the doors will work. Neither the passenger nor driver side power door buttons work in either direction. When I press the button I can hear the relays clicking in the fuse panel, but nothing happens.

I have an aftermarket alarm and thought that may be the culprit but I disconnected it which had no effect. Ive checked all the fuses in the panel and alarm, and even tried replacing the relays even tho they seem to be getting power and working but still nothing. I hooked up a multimeter to the solenoid connector in the door and I'm not getting any power when the buttons are pressed so I'm thinking the issues lies between the solenoids and relays.

What have I missed? I cant seem to think of anything else to check.

 

I'm in the same boat, and have been for a while. I can hear the relays clicking under the dash when I push the lock buttons too, for both sides, but nothing is moving.

Does the BCM have anything to do with the power door locks? Honestly, I'm wondering if that has flaked out on me, cause I'm also getting issues with my blend control motors for the HVAC system.

 

From tracing wires the two that control unlock and lock lead back to the BCM. Atleast that's where my aftermarket alarm was tapped for door lock control.

 

Did you ever solve this problem?

 

Nope never figured it out.

 

For my truck, the problem was a blown fuse in the interior fuse block on the driver's side of the dash. It was a 3 AMP fuse that blew.
