The window switches apparently suffer from current overload when we run the windows up or down all the way. There are no limit switches like in the headlight circuit, so what happens is, we routinely run them until the glass bottoms or tops-out and the motor stalls. The switch contacts are the weakest link in the circuit and don't take this abuse too long. If you hold the switch on long enough, the fuse eventually blows but over time, the switch contacts burn up. If this is happening regularly, I'd suggest adding limit switches in the window switch circuit and keeping the car looking-stock rather than identical-to-how-DeTomaso-built-it.
