Help- my girlfriends 1998 Grand Prix 2 door coupe 3.8l V-6 has the drivers side window inoperable. Tried changing motor/regulator and switch assembly to no avail. Door locks work and passenger window all work fine but no drivers side.
(e.g. driver's side switch operates all except the drivers side window).

What else is there? Don't have a schematic to work with, switch works, motor is new... What to do, what to do...

Any electrical experts out there?

Thanks.
