Closing

When the sunroof control module forward/vent input (terminal C2/7) is grounded through the sunroof switch, the module applies voltage to the sunroof motor assembly from terminal C1/B. The sunroof motor ground is through terminal C1/A.

The sunroof control module runs the motor until the sunroof switch is released or the limit switch closes, grounding the module limit switch input (terminal C2/8). The limit switch closes when the sunroof is in the flush closed position.
