RAM 1500 Truck 4WD V8-5.7L VIN D (2005)
Power Door Lock Switch: Testing and Inspection
Window/Lock Switch
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. 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.
