The Light-Emitting Diode (LED) illumination lamp of the power lock switch receives battery current through a fuse in the Integrated Power Module (IPM) on a fused ignition switch output (run) circuit. The power lock switch on the driver side front door trim panel is integral to the driver door module. (Refer to 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 SYSTEM WIRING DIAGRAMS article.

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.
Test the power lock switch resistance. See POWER LOCK SWITCH TEST table to determine if the resistance is correct for the switch in each switch position (Figure ). If not OK, replace the faulty power lock switch as required.
