The power sunroof system consists of the following components:

The power sunroof system consists of the following components:

The front glass control module and motor assembly contains the logic for opening and closing the front glass panel based on inputs from the sunroof switch. The front glass motor is a reversible DC drive motor with gear train.

The front glass control module and motor assembly determine front glass motor direction based on inputs received from the sunroof switch. When the ignition switch is in the ON position, voltage is applied to the front glass control module and motor assembly through the 40 amp SUNROOF MOD fuse. The front glass control module and motor assembly controls front glass motor direction by changing the polarity of the applied voltage. The front glass control module and motor assembly remembers the front glass position whenever the ignition switch is turned to the OFF position.

The antenna present signal circuit is for vehicles equipped with RPO U2K: Roof mounted ISARS antenna that combines Cellular/GPS/XM. This input to the front glass control module is considered a captured input. Once this circuit is pulled low to ground, the module will always stop the sunroof glass from opening all the way and colliding into the antenna, even if the ground circuit is removed from the circuit.

The front sunshade control module and motor assembly contains the logic for opening and closing the front sunshade based on input supplied on the K-Bus from the sunroof switch through the front glass control module and motor assembly. The front sunshade motor is a reversible DC drive motor with gear train.

The front sunshade control module and motor assembly determines front sunshade motor direction based on inputs received from the sunroof switch through the front glass control module and motor assembly. When the ignition switch is in the ON position, voltage is applied to the front sunshade control module and motor assembly through the 40 amp SUNROOF MOD fuse. The front sunshade control module and motor assembly controls front sunshade motor direction by changing the polarity of the applied voltage. The front sunshade control module and motor assembly will close the front sunshade whenever the ignition switch is turned to the OFF position.

In addition, the front glass control module and motor assembly provide an input on the K-Bus to the front sunshade control module and motor assembly to open the front sunshade when the front glass panel is being commanded to open.

The rear sunshade control module and motor opens and closes the rear sunshade based on inputs from the rear sunshade switch. The rear sunshade motor is a reversible DC drive motor with gear train.

The rear sunshade control module and motor determines direction of the rear sunshade based on inputs received from the rear sunshade switch. When the ignition switch is in the ON position, voltage is applied to the rear sunshade control module and motor through the 40 amp SUNROOF MOD fuse. The rear sunshade control module and motor controls sunshade direction by changing the polarity of the applied voltage.
