Window/Door Lock Switch
WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Light-Emitting Diode (LED) illumination lamps for all of the window/lock switch power window and power lock switches receive battery current through the circuit breaker in the Integrated Power Module (IPM). If only one LED in the door module is inoperative, replace the faulty door module. If the driver side front door power window operates in a normal manner, but the Auto-Down feature is inoperative, replace the faulty window/lock switch. Refer to SYSTEM WIRING DIAGRAMS .
- Disconnect and isolate the battery negative cable. Remove the window/lock switch from the door trim panel. Disconnect the door wire harness connectors from the switch.
- Test the switch continuity. See the Switch Tests chart to determine if the continuity is correct for the suspect switches in each switch position. If not OK, replace the faulty window/lock switch as required.
