75 power window problem
I am having an intermitent power window problem with my 75 coupe.The windows work off and on for both side doors. I checked and cleaned both switches and the 30amp breaker.I think the problem might be with a faulty ground wire. Can someone help me with the wiring connection routing?

Do they fail when trying to lower them or when trying to raise them or both?
When they are failing, as you push the switch, look at the ammeter to see if it's showing a draw. If it is you probably have a problem at the motor. If it does not show a draw you may have a bad swicth even though you've cleaned them. These cars eat up PW switches and intermittant failure is the first sign.
Good luck,
Greg
