To Vent Open
WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
Opening the sunroof glass, to the vent position, can be done when it is between fully closed and full vent. To vent open, pull down on the front of the sunroof switch. This will apply the sunroof switch low reference circuit to the sunroof switch open vent signal circuit. Holding the sunroof switch in the vent position will cause the sunroof switch open vent signal circuit 12 volt reference) input to be pulled to 0 volt. The constant low input to the sunroof module indicates a vent request. Once the vent request has been initiated, the sunroof motor/module assembly will drive the motor in the closed direction (to vent position) until the sunroof motion is terminated by either:
- The sunroof glass reaches the full vent open position.
- Releasing the sunroof switch.
