WHEN I OPEN THE SUNROOF ON MY CAR, IT WILL STAY OPEN FOR ABOUT 2 MINUTES AND THEN CLOSE ON ITS OWN.

Posssible faulty switch or control module !

DESCRIPTION & OPERATION
Sun roof switch is located in the roof console. Sun roof operating features include tilt, and one-touch slide opening and closing. The sun roof can be stopped in any position by pressing switch a second time. The sun roof is operated by a cable and lever mechanism driven by an electric motor.
The Sun Roof Control Module (SRCM) controls the motor, in response to selections made on sun roof console switch, or input from security system for automatic closing.
In the event of an electrical failure, sun roof can be manually operated by inserting a wide-bladed screwdriver into spindle in motor drive gear and turning it clockwise (to open) or counterclockwise (to close).
NOTE:The drive gear becomes disengaged from motor during manual operation. Drive gear must be re-engaged by rotating spindle 1/4 turn in reverse direction.
