I have a ford forte when I turn my air con on it makes a noise then my car stalls?

Ever since it did that even with the air con off it makes like a funny hissing/airflow noise it's hard to explain. I'm worried because I'm ment to be going on a long drive tomorrow

Sounds like maybe the compressor is bad, and you probably gonna have to go to the mechanic for that.

No such thing as a Ford Forte. But anyway it sounds like the compressor has seized up. It's probably going to need to be replaced. Keep the A/C off and it should be okay.
