Modules which activate the power door lock motors receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The DDS or PDS monitors these inputs and sends a LAN message indicating a change in the switch's respective position. When placed in either the lock or unlock positions, the switches provide a direct input to the DDS or PDS. The switches are 2 position normally open rocker switches.

The front power door lock switches are integral components of the driver door module (DDS) and passenger door module (PDS).

The reversible door lock actuators in each of the doors and liftgate.

The power door lock system consists of the following components: The passenger side has another power supply ,that's why they still work. The power locks are controlled by electronic's.

Turn ON the ignition, with the engine OFF. Your best bet, take your vehicle to a qualified repair shop ! Need special tool to diagnose. Since the door lock actuator lock control circuit is at ground potential within the BCM, the driver passenger door lock actuators transition to the Unlock position. When the body control module (BCM) detects a transition of either of the door lock switches to the Unlock position, it switches the door lock actuator unlock control circuits to voltage.

The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:

Door lock actuators in each of the doors.

The Power Door Lock System consists of the following components: Do you know anything about automotive electronic's ? anti theft alarm remote, could this be part of the problem, No it's just a key less entry remote, nothing to do with the anti-theft. The driver an passenger door switche's are input's to the BCM. So just a word of warning to be careful not to short stuff out with the juice connected, bad things could happen.The locks on your vehicle are electronically controlled by the BCM - body control module.

This kind of freaked me out like I had shorted something out and blown up the computer. I turned the truck off and back on and everything went back to normal. As I was doing this, the truck suddenly freaked out and gave me every possible warning (airbags, anti-brakes, engine, etc.) and the DIC appeared to have been totally wiped out (no trip mileage, no MPG, no fuel used, etc.). If I squeezed it just right, everything would start working, but stop as soon as I let go. I could hear clicking like electrical relays engaging as I did this. I found the problem by squeezing the rubber boot with my hand. Anyone ever replace this whole wire bundle (harness)? Is there a part number?Īnother note on this. It is only a matter of time before something else (or my repair) gives out. I'm afraid this is only a temporary fix because the other wires were brittle and the insulation was cracking. I spliced the wire with a crimp fitting and everything is back in business. I'm guessing this wire was related to supplying main power to the whole door. The wire in question was bigger than the other wires, like 10 or 12 gauge. I pulled back the rubber 'boot' and found a black wire that had broken from fatigue (bending back and forth as the door opens and closes).

It was a wire that had broke in the area where the wires go through the gap from the body to the door through a rubber flex tube.

Also, the dash display kept telling me the door was open. Nothing worked - windows, locks, heated seats, mirrors all dead. I just had this same problem on my driver door.
