    Squealing when A/C on?

    recently i noticed when my a/c is on i hear this squealing thats very high pitched and only is on when the fan is on also. When i'm driving the sound is audible every few mins and would fade out. I'm not familiar with the a/c system but everything else seems fine. The a/c blows cold.

    I've thought about bringing it to the dealer but the only problem is i currently have a broken strut mount bolt. Would they give me problems for that or write it down for future reference?

    Well if you have aftermarket struts and or springs I don't think it matters when you take it in. As for the squealing it's probably just a belt that isn't on tight. It could be worse, but I'd check the belt first.

    With the car running turn on the AC and watch it for a minute (not too long though). And see if it trips on and off, and when it makes the noise. Then spray a little belt dressing (just a little) on the belt.. if It's a very frequent noise you can just use water and listen. If the noise goes away for a while it's the belt thats causing the problems.

    Edit: actually, maybe it will make noise if you turn it on and off a couple times.
