Power Windows

The window lift motors are of the permanent magnet type. A battery positive and negative connection to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these same two connections will cause the motor to rotate in the opposite direction. Each individual motor is grounded through the master switch.

DIAGNOSIS AND TESTING

WINDOW SWITCH
Remove the switch from its mounting. Using an ohmmeter, test the window switch for continuity in all positions. If the results are not obtained, replace the switch.

WINDOW MOTOR
1. Remove door trim panel.
2. Connect positive (+) lead from a test battery to either of the two motor terminals.
3. Connect negative (-) lead from test battery to remaining motor terminal.
4. The motor should now rotate in one direction to either move window up or down.

a. If window happens to already be in full UP position and motor is connected so as to move it in UP direction no movement will be observed.
b. Likewise, motor connected to move window in DOWN direction no movement will be observed if window is already in full DOWN position.
c. Reverse battery leads in Step 2 and Step 3 and window should now move. If window does not move, remove motor.

5. If window moved completely up or down, the test leads should be reversed one more time to complete a full window travel inspection
6. If window does not move, check to make sure that it is free to move.
7. It is necessary that the window be free to slide up and down in the glass channels. If the window is not free to move up and down, the window lift motor will not be able to move the glass.
8. To determine if the glass is free, disconnect the regulator from the glass lift plate and slide the window up and down by hand.
