Express Open

The express open will work only with the glass in between the closed and partially open positions. To express open the power sunroof, turn the ignition ON, with engine OFF. Press the rearward portion of the sunroof switch once. This will apply the sunroof switch low reference to the sunroof switch signal open signal circuit, 5 volt reference, input to drop to 0 volts momentarily. The momentary 0 volts input to the sunroof module indicates an express open request. The sunroof glass will lower slightly, then begin to automatically express open between the roof and headliner. The sunroof glass will soft stop at the full open position based on the inputs from the sunroof 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, as the sunroof is expressing open, press the sunroof switch again, in either direction, to stop the movement.
