Power Door Lock Switch: Testing and Inspection
Power Lock Switch with Window Switches
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 Totally Integrated Power Module (TIPM). If all of the LED's are inoperative in
the DDM, be certain to diagnose the power window system before replacing the switch unit See: . 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. See Wiring Information.
1. Disconnect and isolate the negative battery cable. Remove the DDM from the door trim panel. Disconnect the two door wire harness connectors
from the DDM.
2. 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. If not OK, replace the faulty DDM as required.
