Power Sunroof Does Not Open to Vent Position
POWER SUNROOF DOES NOT OPEN TO VENT POSITION
DIAGNOSTIC AIDS
If the sunroof is experiencing an intermittent inoperative condition, check the sunroof switch ground circuit for an open condition. If the sunroof switch ground circuit is open, the switch may take a redundant path to ground through the illumination circuit. When the lights are turned ON, the redundant path to ground is removed, and the sunroof will become inoperative.
If the sunroof open vent switch signal circuit is found to be short to voltage, the sunroof switch will most likely be open.
