If I run the defroster with my A/C... occasionally I hear a squeal. There have been a couple times when I turned on my A/C or defroster, and turned my fan on high, the blower system would stall on and off quite rapidly blowing full force in frequent spurts interrupted by little air flow. I am guessing compressor. Any Ideas?

Is the squeal coming from the serp belt? If so, make sure it is tight and not slipping. As far as the fan blowing hi then low, it may be related to the alt slipping from a bad belt or tensionier.

Let me know what you find.
