Power Lock Switch

POWER LOCK SWITCH

The Light-Emitting Diode (LED) illumination lamp of the power lock switch receives battery current through a fuse in the Totally Integrated Power Module (TIPM) on a fused ignition switch output (run) circuit. The power lock switch on the driver side front door trim panel is integral to the window/lock switch. Diagnosis and Testing If the power lock switch operates, but the LED is inoperative, check for battery current at the switch with the ignition switch in the On position. If OK, replace the faulty switch. Refer to the appropriate wiring information.

1. Disconnect and isolate the battery negative cable. Remove the power lock switch from the door trim panel. Disconnect the door wire harness connector for the power lock switch from the switch connector receptacle.
2. Test the power lock switch resistance. See the Power Lock Switch Test chart to determine if the resistance is correct for the switch in each switch position. If not OK, replace the faulty power lock switch as required.
