Express Open

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The express open will work from the closed or partially open position. To express open the power sunroof, momentarily press the sunroof switch rearward. This will apply voltage momentarily through the sunroof switch open/tilt down contacts through the sunroof switch open signal circuit to the sunroof module indicating an express open request. From the closed position the sunroof glass will lower slightly, then automatically slide open the glass between the roof and the headliner, to the full open position. As the sunroof glass expresses open, the wind deflector will raise upward and the sunshade will move with the sunroof glass. 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.
