Help please. Window doesn't clear top
			 
			 
			
		
		
		
			I'm having a new problem with my 2002 Boxster.  When I open the driver's side door, the glass only drops approximately 1/4 inch instead of the amount required to clear the top.  When I open and close the door the glass hits the top.  Is there a reprograming for this or is it a part that I can replace DIY?  Thanks.
