Corvette: 1973 corvette Power Window

Fuses should power both windows and other accesories, but I'll check em
anyways... Check your wiring... Probably a broken wire due to age, etc.

If, as you say, no power is going to the switch, look for a broken
wire or connection supplying the switch. Since the other window works,
it must be getting power, so you should only have a short bit of wire
to trace.

The hot wire is working assuming that the single prong is the hot wire.
The other two are not so I guess it's a ground problem but I don't have a
clue as to fixing it.

Grounds fall off of Corvettes. Because of the fiberglass bodies, ground
wires have to be run to the chassis. The easiest way to track it down is
with the manual. The manual is something you should have anyway for a car
that old. All of the major Corvette people (Ecklers, Corvette Central,
etc.) have them. Well worth the $.

If the hot wire is working, it can be either a ground problem or a
switch problem. If you know that power is getting "to" the switch and
"through" the switch, but the window motor doesn't work it's a ground
problem. If you know that power is getting "to" the switch but no
power goes "through" the switch then buy a new switch. They're
available from Mid America or Corvette Central, and they aren't too
expensive. If you've gotten far enough to be able to tell that power
is getting to the switch it's trivial to replace it.

Thanks for all the help. From what everyone has said it seems to be a ground
problem with the wires that go to the switch that is not working.

Check for power at the pink wire (gm accessory circuit) at the switch, and
at the fuse box. It will be a acc. feed plugged into the box there. If hot
at the fuse box (p/w dont use a fuse, they use a cicuit breaker), then wire
is probably broken in the flex between the door and the jamb.

The Clymer diagram shows the pink (circuit 70C to both
switches) being supplied from the same terminal on the
power window relay. For the left motor, the light-blue
wire is 'down' and the brown wire is 'up.' For the right
motor, dark-blue is down and tan is up. Clymer doesn't
show the ground returns. I recall that a bad contact inside
a driver's side switch on a '79 caused me some fits finding
the problem. Clymer shows the switches as being
interchangeable (I'm not sure that was the case for all
years though.) If the switches are the same, swapping
them might be a good ploy.

Hope this helps.
