Hey guys, I have a 07 Fahrenheit that really squeels sometimes at idle. It seems to happen more often after I get in to the gas a little. Any thoughs on what's going on? Thanks.

 

could be the A/C compressor, i know they squeak alot when there going bad, or a serpentine belt or tensioner. Hope that helps

 

Serpentine belt for sure. How many miles do you have on it? hillsboro oregon auto repair mechanic for mercedes benz

 

Found out finally yesterday what the problem is. Your air control valve will squeel (after the car warms up) when it's going bad. I knew it would make your car idle funny (wich mine is) but I didn't know it would cause a squrrl like that. Thanks for everyones inputs. Cheers!
