What is another name for a door module? I cannot find a keyword to replace the apparently defective part or is this a dealer part only?

Thank you , anybody

Extracted for XJ service manual

POWER LOCK SWITCH

The power locks are controlled by a two-way switch

that is integral to the Driver Door Module (DDM)

and the Passenger Door Module (PDM) mounted in

the trim panel of its respective front door. Each

switch is illuminated by a light-emitting diode when

the ignition switch is turned to the On position. The

power lock switches provide a hard-wired lock or

unlock signal to the power lock system control circuitry,

which is located in the PDM.

The power lock switches and their lamps cannot be

repaired. If the switches are damaged or faulty, the

entire PDM or DDM unit must be replaced.

Good info. It seems the DDM on mine is bad since I can't ajust my mirrors and if the passengers want to use their window switches I have to jiggle the driver side DOOR lock switch...or am I barking up the wrong tree?

i could not open any of the windows from their own switch, as if they were stuck in locked position. i could only open them from the DDM.

i a took out the DDM, and tested pin 8 of the C1 connection(the little one) with pin 8 of the c2 connector(big one) and found out it was a problem with the window lock button. to solve it, i opened the DDM and soldered a cable from the switch pin to the nearest point i could find that was equivalent to pin 9 of C2..bypassing the windows lock switch. now, all windows work, but the window lock button is disabled...too bad.

hope this helps some one.
