did a search and read the good sources from the window thread, but I haven't seen this one discussed. Driver's door - just started today - when I open or close the door, the window goes down as it should, but then immediately goes back up, causing the glass to be outside of the roof channel when the door is closed again. I am afraid I'm going to break the glass. Getting in, all I have to do is lower it a bit and then manually raise it, and it goes back up into the proper place in the window channel in the roof. When I get out and park, I can't do anything except try to close the door real fast.
I tried resetting it per the manual and the advice here, but no luck. Is it a microswitch? Is failure sudden? I had the roof open in the service position today for a bunch of engine maintanence - could that have affected anything?
Thanks in advance.
