Windows: Testing and Inspection

CIRCUIT TEST
The following circuit test sequence determines whether or not voltage is continuous through the body harness to switch.
1. Remove the driver door trim panel.
2. Carefully separate wiring harness connector from switch body.
3. Using a voltmeter, connect the ground lead to the Pin 10 of the wiring harness connector.
4. Using the positive lead, check Pin 1 of the harness connector for battery voltage. If OK, refer to Window Switch Test. If not OK, check 30 amp circuit breaker in the Junction Block. If the circuit breaker is OK, repair wire as necessary. For wiring, specific connector type and location, 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.

WINDOW DROP RELAY TEST - JR27 ONLY
The following test should be performed if all windows do not lower when the top switch is in the down position.
1. Check for battery voltage at pins Cl, Fl and Dl of the window drop relay wire connector. If OK, go to STEP 2. If not OK, check the circuit breaker and fuse or check for a shorted or open wire. Repair as necessary.
2. Check pin Dl of the window drop relay wire connector for ground while pressing the top down switch. If not OK, check the power top up/down relay wiring. If OK, replace the window drop relay.
