Vent Window Motor Test
- Connect positive battery test lead to either motor terminal. Connect negative battery test lead to remaining motor terminal. Motor should now rotate in one direction moving window open or closed. If window is in full closed or open position, no movement will be observed in that direction.
- Reverse battery leads. Window should move in opposite direction. If window moved completely open and closed, motor should be reversed one more time to complete a full window movement inspection.
- If window does not move, remove the motor and cable assembly. Refer to VENT WINDOW MOTOR or VENT CABLE & CRANK MECHANISM under REMOVAL & INSTALLATION. Service and repair as necessary.
