i changed the headunit in my 1998 Ford Au Fairmont and now the electric windows wont work at all i checked the relays and the circuit breaker fuse and there all getting power i can hear the relay opening and closing but they still wont work they worked perfectly before i changed the radio.

Any suggestions?

Pull the drivers switches out and check for power on one of the grey w/ yellow trace wires... One should be powered if you have supply there and the second is the power send to the back switches...

Cheers,
Tim
