This sounds like you may have a bad lock actuator, there is an actuator that controls the lock, it may need replacing, you will need to remove the door panel to gain access to it, then with a testlight you will test to make sure the actuator is getting power and a ground and if it tests good for power and ground then replace it and door lock will start working again, this part is about 30.00 dollars. here is a picture of it. good day2002 Expedition driver door won't lock/unlock  - 3_10_2013_6_17_11_pm.jpg

SOURCE: 2002 Chrysler T&C sliding door won't UNLOCK w/ Switch or Key FOB

the other locks work correctly.

quick fix is to clean the contacts that the door makes when you close it. there are contacts on the door pillar (probably look like little copper circles) on the door itself there will be some spring loaded contacts... make sure they work freely and are clean.

sorry not sure the 12v prob will help this swtich works on 5v off 3v unlock 1v lock single wire lock/unlock logic signals
I found wiring diagrams at
http://www.dodge.com/bodybuilder/2004/docs/wd/rswd/tc.pdf
it is 2004 but use the wiring diagrams to test the wires
(most likely to fail where they flex)
because it is using logic gates disconnect the plug at each end of the wire you are testing or the damn thing will find a few diffrent ways to trick you.

You will probably need to replace the power door lock actuator.

Here's a link to one similar to yours.

You can probably get a used one from a salvage yard.

SOURCE: Front driver door won't open from the inside only

The linkage is probably broken or snapped out of place from inside the door panel.
You'll feel that the handle is much easier to move than the other doors.

If you are confident and able, take the door apart removing the screws and snap pieces and look for the missing linkage. It's usually a snap piece that holds a rod in place on the back of the handle. They break all the time, or dry rot, or jarr out of place. They're easily available at your local auto parts place or even dealership for just a few bucks!

Good luck!

Where are the fuses for the power dock locks on a 2006 montecarlo06ss


DR/LCK fuse 25 amp . located in the I/P block
Fuse Block - I/P
In the right front kick panel

Power Door Locks System Components
The power lock system consists of the following components:
• Body control module (BCM)
• Driver door lock cylinder switch
• Front passenger door lock cylinder switch
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• DR LK Fuse 20-amp
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A door lock cylinder switch unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation (Personalization function)
• An automatic door unlock actuation (Personalization function)
Door Lock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the lock position, it switches the door lock actuator lock control circuit to voltage. Since the lock actuator unlock control circuits are at ground potential within the BCM, the door lock actuator motors transition to the lock position.
Driver Door Unlock Operation
When the body control module (BCM) detects a transition of either of the door lock switches to the unlock position, it switches the driver door lock actuator unlock control circuit to voltage. Since the door lock actuator lock control circuit is at ground potential within the BCM, the left front (LF) door lock actuator motor transitions to the Unlock position.
The driver door lock actuator unlock control circuit is a dedicated control circuit used only for the driver door lock actuator motor. This is done so that the driver door may be unlocked by itself using a keyless entry transmitter or an automatic door unlock function (if programmed).
Passenger Door Unlock Operation
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. Since the door lock actuator lock control circuit is at ground potential within the BCM, the passenger door lock actuator motors transition to the unlock position.
The door lock actuator unlock control circuits are dedicated control circuits used only for the passenger door lock actuator motors. This is done so that the driver door may be unlocked separate from the passenger doors using a keyless entry transmitter or an automatic door unlock function (if programmed).

2002 Cadi Deville, can't get any locks to operate with remote or dash push buttons, the remote operates everthing but the locks! When the remote door lock is pressed, lites flash,horn blows locks not.


Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Power Door Lock Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch


?€¢
Passenger front door lock switch


?€¢
LH rear door lock switch


?€¢
RH rear door lock switch


?€¢
LH middle door lock switch (w/ V4U)

Power door lock switch?


Sounds like the drivers door lock switch is bad an as far as the auto start remote the contacts under the button get dirty and won't make contact, open the remote like changing the battery and you can probably get at the contact button, if it's a little carbon button they can be cleaned with a pencil eraser and then paper tower with a bit of rubbing alcohol, if it's an actual switch you can try spraying some contact cleaner into the switch. let it dry before you put the battery back in.

The doors will not lock or unlock from the door but will from the remote?


The title suggest the door won't unlock unless the remote is used but during the summer it was the inverse. If while inside the car the doors will not lock or unlock from the door but will from the remote then you have a faulty switch.If while outside the car the key turns while in the lock but the door won't lock or unlock then the linkage at the end of the lock is faulty. You'll need to remove the door inside plate to check this.
