Diagnosis And Testing-Driver Door Module

WARNING: This page is about a different car, the 2004 Dodge Dakota and 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

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.

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.
Test the DDM switch continuity. See the Driver Door Module Switch Tests chart to determine if the continuity is correct for the suspect switches in each switch position (Fig 1 ) and/or (Fig 2 ). If not OK, replace the faulty DDM as required.
