I had the same problem last month. I took it to get evacuated and refilled and they told me that my a/c compressor was bad. I told them to just to evacuated again so that I can replace it myself. Ordered a compressor kit on ebay for $169 that included everything. It took me about an hour and a half to replace it and 45min -1 hour for the shop to pull vacuum and add refrigerant again. Problem solved. I also replaced my aux fan becuase it was dead. My a/c blows cold now!
