Electric Windows Opening Themselves

[rgt160172]

Came out to the garage in the summer to get the 996 C2 MY2002 out and noticed windows open. Strange, must have left them open I thought. Didn't think much more of it until this week. Drove off to work early Monday morning and after a mile both windows auto wound down. I had to wait til they'd fully lowered before they'd go up again. Another 5 miles later they dropped down again. What!? Then no problems the rest of the week and I drive about 30-50 miles per day. However, came out of work this evening and both windows open!!!!

Anyone suffered similar?

My husband had a similar fault on his Audi A4 but it was the sunroof which opened by itself. It turned out he needed a new harness. Hope it isn't the same for you!

Just sorted out a similar problem, but in reverse. Anything open (i.e. windows or roof) would suddenly close without warning. The problem became so acute that eventually whatever was open would close almost immediately it had been opened. Annoyingly the problem was not consistent which made it difficult to diagnose because invariably it wouldn't manifest itself when required. After a great amount of head scratching in the end it was fixed which involved a new alarm control unit (plus key fobs) and two new window motors.
