SUNROOF ACTUATOR (MOTOR) TO MODULE TIMING [1996-2002 SEDANS & 1997-2002 COUPES)

Notice

The sunroof motor has an internal microswitch which opens the motor circuit (turns motor off) when the glass reaches the full vent position. If the motor is operated separate from the sunroof module, or position of the sunroof is changed without the motor installed, the timing of the sunroof motor to sunroof module will be out of phase. Putting the motor installed, the timing of the sunroof motor to sunroof module will be out of phase. Putting the motor back into the module while out of phase will result in loss of vent positioning feature. If the motor and module become out of phase, or the vent positioning feature is not functioning, use the following procedure to re-time the motor.

Use sunroof switch to operate actuator until glass is in full vent position.
Disconnect actuator connectors.
Remove sunroof actuator. (Refer to "Sunroof Actuator (Motor)" removal procedure in this section).
Re-install connectors.

Important

The Vent position is the first detent of the sunroof switch. If the switch is pushed to the second detent, which is the OPEN position, the actuator will not be timed.

Push sunroof switch to VENT position and hold unit actuator stops. Actuator is now timed to vent position.
Install actuator. (Refer to "Sunroof Actuator (Motor)" installation procedure in this section).
