Sunroof / Moonroof: Description and Operation

With the ignition switch in ON (II), voltage is applied through fuse 1 to the coils of the moonroof "open" and "close" relays.

When you move the moonroof switch to the OPEN position, ground is provided to the coil of the moon roof "open" relay. The coil contacts then close, providing voltage through fuse 29 to the moonroof motor, the motor runs, and the roof opens. The motor is grounded through the contacts of the moonroof "close" relay.

When you move the moonroof switch to the CLOSE position, ground is provided to the coil of the moon roof "close" relay. The contacts then close, providing voltage to the moon roof motor, the motor runs and the roof closes. The ground path for the motor is through the contacts of the moon root "open" relay.
