Air Conditioning problem
1999 Subaru Forester 4 cyl All Wheel Drive Automatic 90,000 miles
My 99 Forester makes a loud squealing noise when I start it with the AC on. The AC cools just fine. At higher speeds this two second long loud squeal turns into more of a short squeal/air woosh sound like " pshhhhhhhh.&Quot; It happens at regular intervals while driving anytime the AC is on. It sounds fine when the AC is off. What do you think the problem is?
