I just bought a 2007 Jeep Wrangler X and the A/C was blowing cool, definitely not cold. Added a little A/C Pro Cold into the system like the instructions said and now it is blowing warner then when I started. Looking at the compressor now and and it comes on, runs for a couple of seconds and then shuts off. Does this mean it has too much refrigerant in it? If yes, how do you release some? Anyone here have a shop that I can take it to, to get it fixed and charged for a decent price?
