My passenger side window wont go up through 1 touch I have to hold it down. All my other windows work with 1 touch. How can i fix this???

Disconnect the battery and leave it for a few minutes. Sometimes the anti-pinch programming in the 1 touch windows gets confused. When you power the car back up, you may need to raise and lower each window before the 1 touch works. The motors need to "learn" how to do 1 touch.

Make sure you have your radio code before you do this or else no tunes for you!

I don't know if it's applicable but on the E36, if one touch doesn't work, you can reset it by holding down the window switch five seconds after the windows are all the way down. Try this. Or you can try holding the switch in the up position for five seconds or more.
Good luck.

my e39 had all kinds of electrical mishaps. pulling the battery cables for 5 minutes all ways took care of any problems
