For 1990-2009 cars

Important: An improperly timed window panel can affect sunroof functionality, water test results, and windnoise. If a repair involves the removal of sunroof motor for any reason, it is recommended that the window timing be reset.

1. To reset window timing, the motor must be removed. Refer to Power Sunroof Motor Replacement.
2. Open the sunroof window to the fully vented position.
3. Apply even pressure to the front of the window to move it to the fully open position.
4. There is a hard stop at the rear of the full open position, which will stop the left and right cables in an identical rearward position.
5. Once fully open and timed, the motor may be reinstalled.
6. The motor is not timed to the position of the window, as the motor will continuously run in either direction until the switch is deactivated. Once the motor is reinstalled, test sunroof for functionality. The left and right sides of the window should move, and close, simultaneously. Both rear corners of the window should appear to be the same height, in the relation to the upper frame when in the closed position.
