Limit Switch

The limit switch lets the sunroof control module know when the glass is in the flush closed position.

When the sunroof is in the flush closed position, the limit switch is closed. This grounds terminal 8 CKT 132 (RED) of the sunroof module. When the sunroof is either in the open or vent position, the limit switch opens removing ground from terminal 8.

The limit switch receives ground from the sunroof control module through CKT 133 (YEL).
