Is the accumulator located between the battery and the driver side headlight? What is the switch I jump, the electrical plug? I was also wondering if the compressor was located near the bottom of the car? Are the hoses with the high and low pressure testers where I should be feeling for hot and cold lines? I did not find any hot lines but the one coming up from bottom on the passenger side and into the front of the radiator was a little warmer than the rest. I also thought I could here some intermitten clicking off and on from what I assume is the compressor, does this mean it is cycling? How high of a pressure gauge do I need to test the system. I have read numbers from 24 to 400 psi, will the pressure gauge that comes with the r134 kit be good enough to test the high and low pressure?
