HI, my chrysler voyager ac was not working so I bypass the clutch rlay and compressor started but the low pressure pipe did not frezzes . So I when in a garage to fill with gas, they did the complet job with vacum, leaks test, 10ml oil, UV and gas (0,96Kg), but still the crompressor did not work unless by bypass on relay.
I tested the circuit and is good, and mesure the pressure transducer and was with 3,6 volt ( has 3 wires, one ground and the others 2 where I made the mesure) , so 3,6volts is good pressure and for the clutch to engage it need to be between 0,451 to 4,519 ,
So I dont know why the compreeor is not working, the relay that controls the clutch is operated by the pcm grounding that relay, so I go to the pcm and conect the wire to groung and it engages the clutch.
I make the diagnostics in control panel but the colddown diagnostics ends always with the ac and rear wipe flashing.
what should it be the problem?
thanks
