Hello, so far it sounds like a bad fan run capacitor ($7) or a bad fan motor ($400 and up installed depending on the brand and model number of the unit. Get me that I can be a lot more specific. Tell me if you want to do the work yourself and need coaching or not in the diagnosis and then on doing the actual work. We can go from there.
