- So I bought back my MC cobra from my buddy. When I sold the car in 2015 the AC worked just like it should. My buddy never drove the car and only put 500 miles on it in the last four years. On my way home Saturday, I turned on the AC and its blowing hot air. So here's the issue I'm having. I went to Walmart and bought a recharge car with a gauge on it. I plugged in the gauge today and it went to "full" without me doing anything. I then heard a single clicking noise and the gauge dropped down to zero but then would slowly move back up to full. It did this about five times until I just unplugged the can. I ended up not putting any refrigerant in the car because of what the gauge was doing. I know nothing about AC systems but it almost seemed like it was something with the compressor or something of that nature. Does anyone know anything about this or can lead me in the right direction? Also, I am so happy to be back in my old terminator! Thanks
