Windows: Testing and Inspection
POWER WINDOW MOTOR TESTIf the power window motor is receiving proper current and ground and does not operate, proceed with motor test. 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.
1. Remove front door trim panel and sound pad as necessary to gain access to power window motor wire connector.
2. Disconnect power window motor wire connector from door harness.
3. Using two jumper wires, connect one to a battery (+) source and the other to a good ground (-).
4. Connect the Negative (-) jumper probe to one of the motor connector terminals.
5. Momentarily touch the Positive (+) jumper probe to the other motor connector terminal.
When positive probe is connected the motor should rotate in one direction to either move window up or down. If window is all the way up or down the motor will grunt and the inner door panel will flex when actuated in that one direction.
6. Reverse jumper probes at the motor connector terminals and window should now move in opposite direction. If window does not move or grunt, replace the motor.
If window moved completely up or down, reverse the jumper probes and cycle window to the opposite position to verify full operation.
If motor grunts and does not move, verify that regulator is not binding.
WIRING VOLTAGE TEST
The following wiring test determines whether or not voltage is continuous through the body harness to switch.
1. Remove the power window switch and bezel assembly from the driver door. (Refer to ELECTRICAL/POWER WINDOWS/POWER WINDOW SWITCH - REMOVAL).
2. Disconnect wire connector from back of power window switch.
3. Switch ignition ON position.
4. Connect the clip end of a 12 volt test light to Pin 13 in door harness connector at the window switch. Touch the test light probe to Pin 9 and then to Pin 11.
- If the test light illuminates, the wiring circuit between the battery and switch is OK.
- If the lamp does not illuminate, first check the 25 amp circuit breaker attached to the electrical distribution wiring bracket. If the circuit breaker is OK, then check the 40 amp fuse (# 28) in the Integrated Power Module (IPM). If both components 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.
