Window Problem
 

2003 Boxster: On the driver side door when I pull either inside or outside handle the window lowers about 1/2" as it should. When I release either handle the window goes up, which it shouldn't. I know that there is a microswitch inside the door, mounted to the handle, to identify when the door handle has been pulled. Is this switch at fault or is there another switch that recognizes when the door has been closed?
