Ok, I'm completely new to Rovers. My gf and I just bought her cousin's 98 Discovery. It had been sitting for 1-2 years and they gave it to us for 400 bucks long as we could get it running. Needless to say it is now running very nicely (new fuel pump). After replacing the fuel pump I rolled down all the windows to let the gas smell air out and when I rolled them back up the rear right window would not move. The motor is still running when I press the switch but it doesn't move the window. The window is not stuck and i can pull it up and down by hand very easily. Any suggestions or ideas?
