Sunroof / Moonroof: Description and Operation

The moonroof is opened and closed by a reversible motor. Voltage is applied at all times through fuse 51 to the normally open contacts in the moonroof "close" relay and moonroof "open" relay. With the ignition switch in RUN or START voltage is applied through fuse 23, the moonroof "close" relay coil, and the moonroot "open" relay coil to the moonroot switch contacts.


Opening the Moonroof

When you push the moonroof switch to the OPEN position, the moonroot "open" relay coil is grounded through the moonroof switch OPEN contacts to G303. The coil energizes and the moonroof "open" relay contacts close, applying voltage to the moonroof motor. The motor then runs, opening the moonroot. The motor will run until you release the switch. The motor is grounded through the "close" relay contacts to G252.


Closing the Moonroof

When you push the moonroof switch to the CLOSE position, the moonroof "close" relay coil is grounded through the moonroot switch CLOSE contacts to G303. The coil then energizes, closing the moonroof "close" relay contacts and applying voltage to the moonroot motor. The motor then runs, closing the moonroot The motor will run until you release the moonroot switch. The motor is grounded through the moonroof "open" relay contacts to G252.
