Closing

When the sunroof control module reverse/close vent input (CKT 110) is grounded through the sunroof switch, the module applies voltage to the sunroof motor assembly from CKT 127. The sunroof motor ground is through CKT 129.

The sunroof control module runs the motor until the sunroof switch is released or the limit switch closes, grounding the module limit switch input (CKT 133). The limit switch closes when the sunroof is in the flush closed position.
