That's why I suggested possibly switches. In that case, the switches in the
driver's door. GM power window motors fail at a fairly high rate, so it
would not surprise me for a '96 to have two bad motors.
Since it's both windows, I go along with the
"switch in the driver's door" idea.
A ground for the passenger window is carried
through the driver's switch. I've had that
part of the switch fail, killing both windows.
I have experienced two real cases I know for sure where the wire was
broken inside the plastic cover.
One was in my old buick where the wire to one the doors was broken.
Another in my new toyoto hilux.
After two years I had problem with the control computer and it turned
out to be a known problem with the wires.
They were probably too thin and they were broken in more than one
place in areas were nothing was touching them.
The wires were replaced and no problem since.
