My AC would start out blowing cold air, but it would turn hot after a few minutes. I took it to a mechanic who said my compressor was bad and wanted to replace it for $1000+. I couldn't afford it. Later, I went to Hon-Man because my check engine light was on, and I happened to be in the area. They fixed my engine issue, and the AC issue (the clutch needed to be shimmed to reduce a large gap) for $80 bucks. AC works great now.
