About a month after I bought my 2003 Forester the driver window started acting up. It might go down when you hit the button or it might not. Sometimes the auto feature would work some of the way but not all the way. You might hit the button and it start going down 5 seconds later. But when it was down any at all if you tried to roll it up it would work with no problem. Now the window is up and won't roll down. The button was worn out so today I picked up a used master switch and replaced the whole unit. Still won't roll down. So now I'm stumped on what to do next. Thanks for the help in advance.
