In case you have accomplish all of this tests and also the program remains not working a pin to pin voltage and continuity Examine is as a way.
Usage of A/C whilst owning much too little refrigerant during the program makes suction force that will allow air, and so dampness, to enter, due to the suction pressure falling to lower than barometric tension. The seal within the compressor shaft is frequently a lip seal, manufactured to consist of the force in the gas and dealing with the incorrect approach to comprise vacuum. With minor refrigerant fuel offered the compressor can pull the suction strain below zero into vacuum and so enable air to enter previous the lip seal. The acids Therefore designed assault pipework but given that the condenser has the thinnest volume of aluminium (to maximise warmth transfer) it is usually this which fails initial by leaking. With a regular manually managed a/c procedure you should leave the a/c on all the time, even though not making use of it to cool the car.
If all similar fuses are ok another portion during the process that has a substantial failure rate will be the a/c relay. This relay provides main electricity into the compressor by using the method fuse. Find the relay from the fuse panel or electric power distribution center using the proprietors manual.
