Jeff,
7 out of 10 times a non working power window has been caused by the wiring harness rubbing in the hinge area of the door. The wires get weak from being flexed and the harness was too short to begin with, IMHO.
The rubber boot must be cut to gain access to the area they break while in the van�or remove the entire harness and pull the boot back with the harness on a work area.
Visually check each wire and than test with a meter.
Switches are a easy test with a meter.
Motors too.
Check your grounds behind the fuse panel and clean all of them while in there.

If you have not pulled a power window regulator before....take your time.
Any pulling or aggressive handling of the regulator will surely break the flimsy pastic tabs that hold the wires in place that physically move the glass.
Sometimes they can be saved and riveted back in place, but it depends upon where thery have broken.

Subject: Driver's side power Window not working

OK, gang since my mind is on repairs.

Right after Buses of the Corn my driver side window quit working. Passenger
window works fine.

I admitedly haven't done any checking yet - just curious what the general
consensus is as to if it's more likely to be wiring, the switch, or the
motor.

When I press the switch the interior lights dim slightly as normal - like
it's doing it's thing - I kinda suspect the motor.

I know it's the kind of question that could go many ways - just curious
where to look first :)� Thanks.
