Is there a fuse for the air condtioner

there is a fuse for your A/C inside your kick panel.

but the issue here is not caused by a blown fuse. here are the probable causes:

1. freon - either your system lacks/leaks freon. have an A/C mechanic refill your freon and have a leak test.
2. compressor is not engaging - when you turn on the switch of your A/C, you should here a 'CLICK' sound in the engine. this means that the compressor (A/C motor) is already doing its job. have an electrician check if the wires are properly installed in your new unit

I have a 85 coleman a/c unit (6759b714) it started blowing hot air,was cold. what kind of freon do I need? and is the fitting universal?

It's a closed system, no fittings. You can have system recharged but would need to evacuate, cut lines , solder on fittings, re-charge etc and that gets pretty expensive. Usually better off to replace with new and get warranty with it. Do you hear compressor even trying to kick in? It may be something less expensive. Give me a quick rundown on when it ran good last, what appears to be happening now. Maybe I can help.
