Driving my dad's '90 Carat today.  Let the driver's window down, got to work
and it wouldn't go up.
You can hear the motor work for a second or two up or down, but the glass
doesn't move.

I'm assuming that it needs a power window regulator?

Unless it can be something else, I'll order it from one of our venders, then
take the door apart when it comes in.

Thanks,
