My air conditioner is usually awesome for a car with 260,00 miles but recently it will stop blowing cold air(fan continues to blow) for about 45 sec and kick back in--this happens on all levels of fan adjustment from 1-4.It's very random but makes me nervous--my mechanic says my compressor is fine.Any suggestions on this problem would be greatly appreciated!!

 

Is the Freon level low?

Thats what it sounds like.

 

the freon is fine--thank you

 

Maybe a Bad pressure switch
