Door Module: Testing and Inspection
DRIVER DOOR MODULE
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 Integrated Power Module (IPM). 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. Refer to the appropriate wiring information. The wiring information
includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information
and location views for the various wire harness connectors, splices and grounds.
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.
