locate the window switches. In the fuse compartment on the driver's side near the firewall, they will be those silver, square box, looking things. They control the windows, the seats and the auxillary fans. Your fuse indicator chart in the fuse box might tell you which one operates what. But, a quick trial of unplugging and seeing what does or doesn't work will help you to decide which switch operates your problematic window. But, at least you know that it is not the motor or the window tracks that are causing your problem, which to me puts you way past half way home toward solving the issue.
