Sunroof / Moonroof Switch: Description and Operation
Sunroof Switch - Operation
Power Systems
OPERATION
The sunroof is electrically operated from two switches located in the headliner on the courtesy/reading lamp assembly. The power sunroof switch is hard
wired to the sunroof motor/module assembly. 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 releasing the
close button once will express close the sunroof. If the close button is pressed a second time during the express close operation the sunroof will stop in
that position.
The switch is grounded at one terminal and receives a 5 volt signal from the sunroof motor/module on the remaining three terminals. The switch pulls
down the 5 volt reference voltage from the 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 repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness
connectors, splices and grounds.

OPERATION
With the operation of the sunroof control switch, voltage is directed to the sunroof motor, through the switch contacts or control module. If the control
switch is depressed and held depressed the voltage signal is controlled manually through the switch contacts, so when the switch is released the sunroof
stops.
