Q: Air conditioning on 2005 Ford Expedition

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Usually when I turn my A/C on I her the clutch kick on. Now I turn on my A/C and hear nothing and it blows hot air. How can I troubleshoot this problem?

Some main reasons the compressor will not activate:
1) refrigerant pressures too low - due to low refrigerant level (leak?)
2) compressor coil or clutch worn out or inoperative
3) A/C cycle switch failure

I would start by having the system pressure checked. Good luck.
