The compressor turns on, and is charged. The fan works only blowing hot air. Where should I start?

Thanks

high side and low side pressures ? If the compressor clutch is engaging and the cooling fan up front is running and the inside fan is blowing, the pressures will tell if the expansion valve is stuck or not.
