Driver side electric window when i use the one touch function to raise it goes so far then drops again, have to keep using button bit by bit to close it any ideas what is wrong?

If the battery voltage drops a bit too far for the system then the electric window function will be upset. Try getting the window all the way down and holding the button for about 3 secs and then do the same with the window up. That may reset the system. I think that should be in the handbook.
