Hey guys,

This morning on my way to work I stopped at a fast-food place for breakfast and while sitting next to the building I noticed a fairly high-pitch whistle coming from my car. It goes away when I turn the a/c off. I can just hit the 'econ' button to make the noise stop; and it comes back as soon as I turn the a/c back on. It doesn't sound like the belt, but I haven't had a chance to figure out exactly where the noise is coming from. Any ideas...?

Mike
