Owner of a 1996 Impala. I did some research on the forum and have a better understanding of the A/C system. My cars A/C was working about a year ago prior to moving to the Mohave Desert. I now have my car parked in my garage and it's driven only twice a month. Well two weeks ago I couldn't take the 115 degree heat and wanted some A/C. The A/C system was turned on and only blew hot air. I went to AutoZone and explained my story to them and they told me just to add R134 to the system. So I followed the instructions and added the R134. Correct me if I'm wrong: The pulley on the compressor is the clutch right? If so, once I added the R134 with the A/C on high, the pulley (clutch) would come on and off and on and off and so forth. Finally my question, I was thinking I needed to add more R134? If that doesn't work, I'm taking it to the professionals. Am I on the right path? Thanks.
