OK so my A/C has not worked since I bought my cruiser in December. Figuring I had a rear leak from reading other posts I tracked it down to two fittings that were cracked in the rear high pressure line by the rear axle. I found the post on the airsept repair but was wondering if anyone has ever used brake line compression fittings and if they would work on the high pressure 5/16 line. Also I wanted to check my compressor. Using an FSM from a 2004 (my truck is a 2000 not sure if this area is different) my magnetic clutch would not turn on when jumped to battery . Is this supposed to not come on if jumped and there is no refrigerant? My compressor lock sensor resistance was in spec. Anybody have manifold gauges and pump recomondations or just rent from auto zone.
