My air conditioning is not working. Also my heat pump did not work this winter. The diesel heater worked great when it was really cold. Last summer my air conditioning worked some time, it was temperamental. it would start working then after a while of driving a warning light would come on the dash. I believe it was service soon, not 100 % positive. THe air would stop working and the regen would no longer work. Once I got to were I wanted to go shut it off, do what I came to do , then start it up again and repeat the cycle. This did not happen every time. The heat pump has never seemed to work. The other day I went to an airconditoning guy. He hooked up his gauges and said the pressures were about equal and did not look like it needed 134A. He said it looked like an electrical problem because the compressor was not pumping. The fan comes on right away behind the radiator when you turn on the air conditioning. I tried the cycling the aucuator valve. It would clunk back and forth.With the tech 2 hooked up there is no faults showing up. With the aircondioning on there is no amp reading on the tech 2 for the compressor. Everthing else seems to work fine. Any ideas? Or progressive tests I can make? Suggestions for maybe a bad connection somewhere? Thanks Rick
