Express Open

WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

The express open will work only with the sunroof glass in the full vent or any partial open position. To express open the power sunroof, momentarily press the rear portion, OPEN/VENT side, of the sunroof switch once. This will apply the sunroof switch low reference circuit to the sunroof switch signal open signal circuit, 5 volt reference input, pulling the reference voltage to 0 volts. Once the sunroof control module receives the input request, the sunroof control module will control the sunroof motor to express open, automatically sliding the sunroof glass above the roof. The sunroof glass will soft stop at the full open position based on the inputs from the limit switches. As the sunroof glass expresses open so will the sunshade. To stop the sunroof glass in a desired position other than to the express open position, during the express open operation, momentarily press the sunroof switch again, either direction, to stop the movement.
