Newbie to Deloreans here...

The passenger window is in the down position, window switch doesn't do anything nor does giving the motor 12v directly, other than a very quiet click once, so looks like I'll have the replace the regulator. As the door window was open for many years and the car was exposed to the elements I suspect that the motor will be rotted inside.

Is there a way to raise the window temporarily to keep the elements out while I wait for the new regulator? The plastic bag taped to the window isn't the look I'm going for
