Express Open

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The express open will operate from the closed or partially open position. To express open the power sunroof, turn the ignition to RUN. Press the sunroof switch rearward once. This will apply the sunroof switch low reference to the sunroof switch open signal circuit, 5 volt reference input, pulling it to 0 volts. The 0 volts input to the sunroof module indicates an express open request. From the closed position, the sunroof module will control the motor to lower the rear of the sunroof glass slightly and then slide it rearward between the roof and the headliner, along with the sunshade. The wind deflector will raise upward. To stop the sunroof glass in a desired position other than to the express open position, press the sunroof switch, in either direction, to stop the movement.
