Express Open

The express open will work only with the sunroof glass in between the closed and partially open positions. To express open the power sunroof momentarily toggle or pull the sunroof switch rearward. This will apply the sunroof switch low reference circuit to the sunroof switch signal open signal circuit (ignition voltage reference) input to drop to 0 volts momentarily. The momentary 0 volts input to the sunroof module indicates an express open request. The sunroof module will control the sunroof motor to lower the rear of the glass slightly, then begin to automatically slide (express open) between the roof and headliner, allowing the wind deflector to raise upward. The sunroof glass will stop (hard stop) at the full open position. 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, press the sunroof switch again in either direction to stop the movement.
