Dakota Quad Cab 2WD V8-5.9L VIN Z LDC (2002)
Door Module: Testing and Inspection
The Light-Emitting Diode (LED) illumination lamps for all of the Driver Door Module (DDM) power window, power lock, and power mirror switches
receive battery current through the power window circuit breaker in the Junction Block (JB). If all of the LEDs are inoperative in the DDM, be certain to
diagnose the power window system before replacing the switch unit. (Refer to POWER WINDOWS - DIAGNOSIS AND TESTING). If only one LED
in the DDM is inoperative, replace the faulty DDM. If the driver side front door power window operates in a normal manner, but the Auto-Down feature
is inoperative, replace the faulty DDM.
1. Disconnect and isolate the battery negative cable. Remove the DDM from the door trim panel. Disconnect the door wire harness connectors for the
DDM from the DDM connector receptacles.
