To Vent Open

To open the power sunroof glass to the vent position from the closed position press and hold the sunroof switch forward. This will apply the sunroof switch low reference to the sunroof switch close signal circuit (ignition voltage reference) input to drop to 0 volts. As long as the sunroof module sees a constant input request from the sunroof switch close signal circuit (0 volts), the sunroof module will continue to control the sunroof motor to raise the rear of the sunroof glass upward to the full vent position.

The sunroof glass will stop (hard stop) at the full vent position. To stop the sunroof glass in a position other than the full vent position, release the sunroof switch when the sunroof glass reaches the desired vent position. The sunshade will have to manual slid open.
