SunRoof electrical help
 

The sunroof automatically closes shortly after the ignition key is removed unless I push the sunroof button as I exit the car. I want to be able to "lock" (cut off power) the sunroof in the vent position to avoid pushing the button each time I exit the car. Since the mechanism is not working properly anyway, I would like to be able to control when the sunroof motor runs.
Any suggestions?
