Sunroof / Moonroof Switch: Description and Operation
Power Sunroof Switch:
The power sunroof switch is a combination pushbutton and rocker switch mounted in the overhead console. The sunroof switch is a direct contact unit that is directly wired to the sunroof motor/ module assembly. The sunroof switch performs the following functions:
- Power sunroof open
- Power sunroof closed
- Power sunroof vent
The sunroof is electrically operated from two switches located on the windshield header, rearward of the map lamp. The "VENT" switch is a push button type switch and opens the sunroof to the vent position only. The other switch "OPEN/CLOSED" is a rocker type switch for opening and closing the sunroof. Pressing and releasing the open button once, the sunroof will express open and the wind deflector will raise. If the button is pressed a second time the sunroof will stop in that position. Pressing and holding the close button will close the sunroof. If the close button is released the sunroof will stop in that position.
The switch is grounded at one terminal and receives a 12 volt signal from the sunroof motor/module on the remaining three terminals. The switch pulls down the 12 volt reference voltage from the motor/ module signaling it to perform the desired function.
