I have powered locks but the driver door and the rear passenger door don pull the plunger down when activated the lock motor works but the lock dosent pull down or up and the clips to the motor are attatched.

The most likely culprit is a faulty actuator. You can test this by having someone activate the rear hatch while listening for a click or sound of some sort. If there is sound but no opening, it indicates a bad latch actuator. If there is no noise, it could be a fuse or wiring issue. You can manually unlock the door by removing the trim, but be careful around the glass latch as there are 2 push pins.

Check the wiring in the boot that runs from the body to the top of the liftgate for broken wires.

You might have to take it to a collision shop. Remove the rear hatch panel to gain access to the latch assembly if it's not responding. If you can't get it open, take it to a collision shop as they deal with these kinds of things regularly.

You say the driver window works? wouldn't be a main fuse or fusible link then -driver door locks and window wouldn't work either. Each door has a module inside (computer) . The driver door has a circuit breaker power feed an a fuse DDM fuse 10amp located in rear junction block circuit breaker is located in under hood maxi fuse block. The circuit breaker also feeds battery voltage to the other door modules too. PDM - passenger door module fuse 10amp located in the instrument panel fuse box and the RDM - rear door module RDM fuse 10amp located in the rear fuse box - under the back seat.

Each power window is connected to a permanent magnet motor. The motor raises or lowers the glass when the door module applies voltage to the motor. The direction the motor turns depends on the polarity of the supply voltage provided by the associated door module. The 2 front doors have their own separate modules. The rear seat contains a single module, which controls both of the rear power windows.
A serial digital communications link, called the simple bus interface, is used for communications between door modules and the driver's door power window switches. The use of serial digital communications allows the use of a single wire to convey switching information between the power door lock switch and the driver's door module (DDM). The serial communication is also used in order to transmit switching information from the DDM to the other 2 door modules.
The door modules apply battery voltage of the correct polarity to the respective window motor when any local, or power door lock switch, UP switch is operated, driving the window up. Battery voltage is applied to the respective window motor in the opposite polarity when any local, or power window switch, DOWN switch is operated, driving the window down.

Driver Door Module (DDM)
The driver's door module (DDM) directly controls the driver's door window motor and the express down window feature. The DDM sends window UP/DOWN messages received from the power door lock switch to the passenger door module (PDM) and to the rear door module (RDM) over the simple bus interface (SBI) line. The DDM also contains a class 2 data link which communicates with the other vehicle system modules. The left front power door locks and the outside power mirror are also controlled through the DDM.
Passenger Door Module (PDM)
The passenger door module (PDM) controls the passenger's door window motor. The PDM controls the passenger's door window directly from the right front power window switch or from instructions over the simple bus interface (SBI). The right front power door locks and the outside power mirror are also controlled through this module.
Rear Door Module (RDM)
The rear door module (RDM) controls both of the rear door window motors. The RDM controls the rear windows directly from the rear door window switches or from instructions over the simple bus interface (SBI).

Door Lock System Components
The power door lock system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Liftgate Module (LGM)
• Door lock relay
• Door unlock relay
• Body Control Module (BCM)
• Reversible door lock actuators in each of the doors
• LR/RR LOCKS 10A fuse (relay supply voltage)
• Door lock switches in driver and passenger doors (switches are integral components to the DDM and PDM)

Power Door Lock Operation
The power door lock switches are integral components of the DDM and 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 modules which activate the power lock motors are:
• DDM (driver door lock actuator).
• PDM (passenger front door lock actuator).
• BCM (both rear door lock actuators).
• LGM (liftgate door lock actuator).

Could be a lot of thing's causing it not to work . The way we would diagnose is to hook up a scan tool an look for a DTC - diagnostic trouble code in the lift gate control module first ,no codes ,look at a wiring diagram an test voltages at the lock actuator ,switch etc... Also look on scan tool data to see if the lock/unlock command is getting to the lift gate module .

Door Lock System Components
The power door lock system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Door lock relay--Located in the instrument panel (I/P) fuse block and controls the locking of the rear doors.
• Door unlock relay--Located in the I/P fuse block and controls the unlocking of the rear doors
• Body control module (BCM)
• IP BEC
• Reversible door lock actuators in each door

Driver and Passenger Lock System Operation
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 monitor these inputs and send a LAN message indicating a change in the switch position. Modules, that activate the power door lock motors, receive the LAN message and activate the motor in the appropriate direction to lock or unlock the vehicle doors. The body control module (BCM) upon receipt of a lock or unlock signal will control the rear door lock or unlock relays and also send a LAN message to the DDM and PDM to perform the commanded function.
The modules that activate the power door lock motors are:
• DDM (driver door lock actuator)
• PDM (passenger front door lock actuator)
• BCM (both rear door lock actuators)
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 doors are controlled by the BCM through the rear door lock/unlock relay which is incorporated onto the printed circuit board in the LH BEC. The BCM controls the unlock relay by providing ground to energize the coil and controls the lock relay by providing battery voltage to energize the relay coil. 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.

How do you know they need to be replaced ? The switches incorporate a electronic module . Driver door module .
Power Window System Components
The power window system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Body Control Module (BCM)
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left windows)
• RT DOOR CB 25A (System power for right windows)

Power Window System Controls
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The DDM contains four power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the two front windows have three positions UP, Down and Express Down, while the switches for the rear windows have only two positions, UP and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a Class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has two positions Up and Down. Each of these switch positions is a direct input to the PDM.
The two rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a Class 2 message from the DDM, can control the set of relays which will activate the rear window motors.


The door locks operate the same way .

Door Lock System Components

None < LGM - liftgate control module inside the lift gate does .
Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear window wiper motor
• Rear washer pump
• Rear wash relay
• Rear wiper/washer switch
• RR WIPER Circuit Breaker 15A / ENDGLASS REG Circuit Breaker 30A
• WASH 20A fuse
• Body control module (BCM)

Door Locks Go Crazy 1

The power windows an power locks are controlled by a module , DDM - driver door module . As far as the locks locking when you put the vehicle into reverse an unlocking when you put the vehicle into park , that's how there are suppose to work , automatic lock an unlock feature . When you put the vehicle into any gear from park the locks should lock . Did she hit window lockout function ?

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 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 .

Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.

Do you know anything about automotive electronic's ? Serial data Communication network ? Electronic module's inside the vehicle doors , communicate commands ! No relay ,no fuse .
If the passenger mirror is selected and a direction switch is activated, the DDM sends a serial data message to the PDS indicating that the passenger mirror was selected and the direction to be commanded. The PDS will then supply battery voltage and ground to the appropriate control circuits for the direction selected.

Your best bet , take it to a qualified repair shop that has a diagnostic scanner that can pull code's an view input data form these systems . There is one circuit breaker for the window's an fuse's for the lock's . I would think a data network problem . But that would be a guess , without testing anything is possible on these .

Do the power windows work ? DDM - driver door module fuse 15 amp - location is the instrument panel fuse box , plus LT DR circuit breaker 25 amp. Circuit breakers rarely go bad . The power locks are controlled by electronic's .The passenger side has another power supply ,that's why they still work .
