All - driver - passenger - front an back ? Look for broken wires inside the rubber boot from the body to the door ,driver side !

Power Windows Operation
Power Windows
The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. The DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation.
If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.
Windows Power and Ground
The windows are powered by discreet power and ground circuits. These circuits are in the same dedicated connector as the window motor drive circuits.

PWR/WDO 30 amp circuit breaker located in the rear fuse box ,DRVMDL fuse 10amp located in the same rear fuse box . This power the driver door module (computer )

The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted.
The exterior key cylinders are wired to either the DDM or the passenger door module (PDM), depending on the location of the key cylinder. The interior lock switches are wired to the driver door switch assembly (DDSA) and the PDM. The DDSA and the PDM send the lock switch requests to the DDM over the simple bus interface (SBI) serial data circuit. The DDM then sends the lock requests to the RIM over the Class 2 serial data circuits.
The door lock operation modes are controlled by the rear integration module (RIM). The RIM examines the requested function from the DDM, or the remote function actuator (RFA), as well as the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. The RIM determines if a locking function is permitted, and commands the DDM to perform the function permitted. The DDM then sends commands to the rest of the door modules via the SBI to implement the selected locking function.
All programmable modes of lock system operation are stored in the RIM. The RIM checks the lock function program selected against the lock requests, the transmission selection and ignition key switch condition to determine if the requested function is permitted. If the requested function is permitted, the RIM then commands the DDM to perform the lock function over the Class 2 serial data circuits. The DDM commands the individual door modules to perform the lock function over the SBI serial data circuit.


GOOD luck your going to need it !

2003 crown vic keyfob only works with ignition in run position .keyless entry and door locks work fine.even tried new keyfob.no change


The keyless entry system consists of the following components:
  • driver door module (DDM)
  • keyless entry transmitter
  • keyless entry keypad
The driver door module (DDM) receives inputs from the digital transmission range (TR) sensor, ignition switch, brake switch, window/door lock switches, lighting control module (LCM), keyless entry keypad switch and remote transmitter. The DDM outputs consists of keyless entry keypad switch illumination, power door lock actuators, luggage compartment release solenoid, horn relay, and lighting control module (LCM).
  • Battery junction box (BJB) fuses:
    • circuit breaker 7 (20A)
  • Central junction box (CJB)
    • 4 (10A)
    • 6 (15A)
    • 8 (25A)
    • 13 (5A)
  • Keyless entry keypad switch
  • Power door lock actuator
  • Luggage compartment release switch
  • Luggage compartment release solenoid
  • Connectors or connections
  • Wiring harness

B1751 Park/Neutral Switch Circuit Short to Battery DDM Go To Pinpoint Test K . B2425 Remote Keyless Entry Out of Synchronization DDM Go To Pinpoint Test L Need a professional grade scan tool to check fro these codes . Not a code reader for OBD2 codes .
  • The doors do not lock/unlock using the remote transmitter
  • Remote transmitter not programmed.
  • Remote transmitter.
  • DDM.
  • Go To Pinpoint Test F .

Did you program the new key fob ?

Remote Transmitter Programming NOTE: All remote transmitters are programmable and must be set at the same time.
  1. Turn the key from OFF to RUN four times within three seconds, ending in RUN. The locks will then lock and unlock, confirming program mode has been entered.
  1. Press any button on each remote transmitter to be programmed. The doors will lock and unlock to confirm that each remote transmitter has been programmed.
  1. If additonal remote transmitters are to be programmed, repeat Step 3 within 7.5 seconds or steps 2 and 3 if more than 7.5 seconds have elapsed.
  1. To exit program mode, turn the ignition to START or wait 7.5 seconds.
  1. NOTE: Failure to wait at least 20 seconds will cause programming failures. Wait at least 20 seconds after turning the key to OFF or after the last remote transmitter has been programmed to activate a remote transmitter for testing or verification

Trunk will not open using the release button inside a 2004 lincoln towncar


Are you hearing the trunk solenoid engage when you press the button? Check for a blown fuse. Have someone listen at the trunk when you press the button. Check the trunk solenoid for a loose wire or it could be a bad trunk solenoid. If the trunk won't open easily with the key, it could be a sticky trunk lock mechanism.

Need computer location in 2005 lincoln towncar


The code is on a paper label attached to a large plastic box containing several wiring harnesses behind the driver side door panel. Posts about it being on the trunk hinge arms, behind trunk panels, on computer module, behind the fuse box, and 'you have to go to the dealer' are incorrect for this series of Town Cars. After you remove the panel (you do not need to disconnect any wires), you will see the box up near the rear view mirror. An example code (3/4) (1/2) (5/6) (9/0) (1/2). If you press the keypad buttons in this order,left to right, the door locks will operate in the manner described in your opwner's manual.

Do a search on door panel removal to learn how to remove the panel. There are some good posts on this topic - some even have pictures.

1999 lincoln fuel pump


My fuel pump on my 1998 Lincoln Continental has no power. I checked the fuse it is good. I checked the fuel shutoff switch it was fine. I have traced the wire from the fuel shutoff switch to the fuel module driver in the trunk. The wire has power. I have also traced the positve wire from the fuel pump to the fuel driver on a different terminal, this wire has no power from the pump. I also changed the fuel driver, the low fuel pressure switch, the alternator, and battery.does anyone have any suggestion's?

Trunk latch pull down


You could try setting release to work manually. I have had the same problem. Take tne motor off set the catch clip at the right height. This should work with no cost.
