Check that there is nothing stopping the locking movement if the locking part is worn on the pillar it will not lock or unlock properly some times the part that hooks around the lock can wear out and need to be replaced. some times just some w40 can sort this out by soaking the inside of the lock as door is open. road muck can get in there and stop movement. also if the door is not used that much the door lock will start to seize up and not work. same for electric windows if they are not used for a long time.

The only way to know is to remove the inner door panel and check, this can lead to be a real pain if you do not know what you are doing. Take it to a repairman

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.

The power door lock system consists of the following components:
?€¢
Driver door lock switch


?€¢
Passenger front door lock switch


?€¢
LH rear door lock switch


?€¢

Why does my 2004 Chevy Silverado lock and unlock while in drive? When turned off and no keys in ignition the drivers door will unlock on its own a short time later.


Gremlins ! HA HA HA sorry ! First off a little bit on how they work an what all is involved in making them work ! There are a few control modules in the mix , switches ,relays etc...
Door Lock System Components
The power door lock system consists of the following components:
?€¢
The driver door module (DDM)

?€¢
The passenger door module (PDM)

?€¢
The body control module (BCM)

?€¢
The driver information center (DIC)

?€¢
The rear door lock switch

?€¢
The door lock relay

?€¢
The door unlock relay

?€¢
The liftgate lock relay--utility vehicles with liftgate only

?€¢
The reversible door lock actuators in each of the doors and liftgate

?€¢
LOCKS 20A fuse (rear lock/unlock relay supply voltage)

?€¢
ECC 10A fuse (liftgate lock relay supply voltage)

Door Lock System Controls
The power door lock system can be controlled by any of the following:
?€¢
A power door lock or unlock switch activation

?€¢
A keyless entry transmission

?€¢
An automatic door lock function

?€¢
A delay lock function

?€¢
Door lock cylinder switch activation

?€¢
Lockout Prevention

?€¢
An airbag deployment

The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock relays and also send a Class 2 message to the DDM and PDM to perform the appropriate function.
The modules which activate the power lock motors are:
?€¢
The DDM (driver door lock actuator).

?€¢
The PDM (passenger front door lock actuator).

?€¢
The BCM (both rear door lock actuators and cargo door/liftgate).
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and cargo doors differ slightly in that they use lock and unlock relays. The relays supply and coil sides receive a constant voltage through the battery voltage supply circuit. The normally closed contacts are connected to ground and the control side is connected to the BCM. Once a door lock or unlock request has been received by the BCM, the BCM will ground the control side of the appropriate relay. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.
The first place to start is have a factory or equivalent scan tool hooked up , one that can read BCM DTC'S - diagnostic trouble codes ! This could lead to a fix faster ! Watch these three videos !

2009 chevy equinox rear passenger door won't unlock with remote


Lock/unlock motor may be failing. Remove the door panel and remove the connector from the lock motor. Check the dc voltage at the connector while pressing the lock switch. If you see battery voltage, replace the motor. If the voltage is low, inspect the wiring.

My passenger rear door on my 2005 nissan altima will not open from inside or outside


It's not the handles I've struggled with these issues on 3 altimas it's the door latch itself it's from moisture it's worse in the winter if I run the car for a couple hours with heat on the door opens also if you repeatedly lock and unlock the door with the power lock it will release eventually. I've been locked in my 04 Altima multiple times and had to lock the door sometimes to get it to hold shut these cars are nutorious for door issues

All my remotes won't unlock passenger doors, why?


this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.
