That is my issue, the pulley does not even "free wheel"....... Ie. I go outside and turn the car on, AC button OFF, and the pulley on the AC compressor does not even Spin/free wheel. The belt is being dragged across the pulley via all the other pulleys.
I have the AC charge kit at home, and Know exactly where the low pressure port is, but I am thinking I have a larger issue if the pulley on the AC compressor will not even spin freely.
