Operation CHARM: Car repair manuals for everyone.

Express Vent Open

To open the power sunroof to the vent position, rotate the sunroof switch counterclockwise until it stops. The sunroof switch sends a position signal to the sunroof module. The sunroof actuator checks the position of the power sunroof using the potentiometer's signal and drives the motor to move the sunroof to match the new switch setting. The rear of the sunroof glass will raise slightly to the vent position. To open the sunshade, this will have to be manually slid open.
