Message the mechanic charged me with the gas and I think it should continue to be charged, because when I connect the compressor to ground and it turns on I have cold air in the car, if the gas is not under pressure it shouldn't have cold air, is this correct?
I checked the sensor low. (my Z does not have a high sensor). I disconnected the connector and made these two checks: First I measured continuity with a multimeter on the connector of the dryer, and I have continuity right now, that's why I think it has gas pressure. the second check that I did, I put a jumper with a cable in the connector that goes to the car, to force the signal without going through the low sensor, but the compressor does not start like that either.
