Front Door Window Motor: Testing and Inspection
DIAGNOSIS AND TESTING
1. Remove door trim panel. See: Front Door Panel/Service and Repair/Front Door Trim Panel - Removal
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, if motor connected to move window in DOWN direction, no movement will be observed if window is already in full DOWN
position.
c. Reverse battery lead in 2 and 3 , and window should now move. If window does not move, replace 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.
7. The window should slide up and down freely in the glass channels. If the window does not move freely, the window lift motor will not be able to
move the glass.
8. To determine if the glass slides freely, disconnect the regulator from the glass lift plate. Remove the two attaching screws, and slide the window up
and down by hand.
