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.
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector

connectors, splices and grounds.
