My drivers window is not sliding down when I open the door. It has just now started doing this. I have rolled it down several times w/out use of the one touch option in hopes of resetting the cycle. So far it has'nt worked. If i open the door then roll down the window and roll it back up it stops far enough down to close properly. It seems it knows what position its supposed to be in, but will not go down automatically when door is opened. Has anyone found a way of resetting the cycle? Do I need to replace a part?
