Have a slight a/c problem. The other day while driving my a/c just cut off and started blowing hot air. It then started doing this frequently throughout my drive coming on for a while then cutting out. I went to a repair shop where they told me I needed a new a/c clutch. I noticed while my car was parked the a/c cycling on and off every few seconds. I remember someone mentioning that this might be a lack of freon, so i bought a can of freon/oil/leak sealer with a meter. The meter said it was a bit low so I put the can in, it then read between "Normal" and "Low". The clutch all of a sudden stayed engaged and the a/c blew really cold air. Today on my way to work the a/c was ice cold until about 15 min from my job when it cut off AGAIN! When I pulled over to take a look the clutch after 2 min. engaged again and stayed on. I put on a pressure tester to the a/c and it reads right in the middle of "Normal", but when I give the car gas the pressure rises to "Overfilled" on the meter and the clutch cuts out until I release the gas then I hear like air escaping a valve stem and the clutch resumes. Does this sound familiar to anyone? If so, I could use some help. Thanks
