Windows: Testing and Inspection

POWER WINDOW TEST

Wiring Voltage Test
The following wiring test determines whether or not voltage is continuous through the body harness to the front switch.
1. Remove the Driver Door Module (Refer to POWER LOCKS/DOOR MODULE - REMOVAL).
2. Disconnect wire connector from back of power window switch.
3. Switch ignition to the ON position.
4. Connect the clip end of a 12 volt test light to Pin 14 of the window switch harness connector. Touch the test light probe to Pin 10.
- If the test light illuminates, the wiring circuit between the battery and switch is OK.
- If the lamp does not illuminate, first check the fuse in the Integrated Power Module (IPM). Check the circuit breaker located near the park brake pedal. If fuse and circuit breaker are OK, then check for a broken wire.

Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
