Hello fellow T-Bird enthusiasts. I just purchased a 1966 convertible and 3 of my 4 windows do not roll down. Are all of the windows on same fuse? Im guessing this is a switch or relay problem. One of the windows worked initially until yesterday. Any thoughts would be much appreciated!

There is one main safety relay that controls all the windows. If one works then it has to be the switches, wiring, regulators or the motors themselves. Normally the drivers window works because that one get the most use. The other motors and regulators usually stop working because of lack of use and lubrication. I would start by cleaning the switches first. There is the complete wiring diagram for the 1966 Thunderbird in the Technical Resource Library. You can find the link under my signature.
