I have a '76 3.0si in which the rear power windows are not working. The switches are both good and the windows did work when I got the car. The factory wiring diagram shows a front and rear window relay. Can anyone tell me where these relays are located in the car??? All fuses are OK . I am also looking for an under dash panel that goes beneath the steering column area. The previous owner mangled this panel while doing some stereo wiring. Thanks for any and all replies,
