I just had my Classic repaired by the factory. They lost the info, and after a few phone calls they found my order and sent it. Needed a new compressor, line cord, and some sort of bracket inside. Cost about $225 but I bought it used many years ago so I've gotten my moneys worth.
Funny thing, this last weekend I made a tight turn out of a shopping center and all of a sudden the brakes were dragging. The breakaway switch had pulled out and the toad was slowing me down. I was able to go around the corner back into the lot (brakes weren't locked up) and disconnect the switch. Found the plastic plug in the street but it had been run over and is broken. Time for a new switch, but I know it works!
