Left my front windows partly down today to let some air through the car. When I left to go home I wound up the passenger window only to find that every time I got to the top it would go back to the position it started at? I stopped the car and tried all sorts of things including turning the car off and back on. I eventually got it to stay up by bringing it up slowly with lots of small increments. Now I am hoping that I have done something stupid and I have stumbled across a feature I didn't know how to over ride?? Or is there something wrong?
