To Vent Open

WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

To open the power sunroof to the vent position from the closed position, turn the ignition to ON, with engine OFF. Press and hold the forward portion of the sunroof switch. This will apply the sunroof switch low reference to the sunroof switch close signal circuit, 5 volt reference, input to drop to 0 volts. As long as the sunroof module sees a constant input of 0 volts at the sunroof switch close signal circuit input, the rear portion of the sunroof glass will raise upward to the full vent position. The sunroof glass will soft stop at the full vent position based on the inputs from the sunroof limit switches. 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.
