I have a 1995 M3, purchased it new. Since I've had it I have had a problem with my one touch power windows on three seperate occasions. When I depress the button all the way down to raise the window , it goes about 1/3 the way up and stops. I have to depress the window again for it to raise all the way. The dealer has fixed it each time, but I think it is unusaul for this problem to keep happening. Has any one else had this problem? Just curious.
