Hello Fit freaks!
I am a proud new Fit owner (I bought my used '08 in January) and I'm having some trouble with my AC speaking/squealing. I took it to the mechanic and they replaced the serpentine belt and idler pulley, but I still hear the squeak. As I've seen in other posts, the squealing only happens at start up, until the engine warms up, and then it stops. So, I just wait to turn on the AC for a couple minutes and I can pretend the problem doesn't exist. I'm planning to leave my car over night with the mechanic so that they can try to hear the sound themselves. They also mentioned possibly replacing the alternator or the air compressor. I just wanted to get some thoughts on this problem, see if others have had similar experiences, and what their solutions were. Thanks!

 

The continuous squealing sound can come from glazed pulleys or over tightened belt (or cheap belt brand)
The a/c clutch that is not fully releasing due to wear or damage will make periodic sound (one per every pulley revolution rather than continuous squeal)
