Expert Auto Ac Compressor Wiring Diagram Wiring Diagram For A C - Wiring Diagram Database - Discover the compressor snatch relay and dispose of it from its socket. Connect the terrible meter cause battery bad terminal. Probe the relay socket terminals to locate battery power at terminals 2 & three. In case you don’t see battery voltage on each terminals, test the fuses and wiring to the relay. If you have battery electricity on both terminals, connect the tremendous result in terminal 3 and the bad cause terminal four. You must see battery voltage. If you don’t, the pcm isn’t presenting ground to the relay manage coil, pass to step three. If the a/c to your car isn’t operating, step one is to see if the compressor runs while the switch on the a/c and the engine. In case you find out an ac compressor received’t run state of affairs, observe those diagnostic steps to discover what’s incorrect. You’ll need a digital multimeter and a wiring diagram or parts locator to locate the excessive and low stress switches. If you see battery voltage on one terminal, leave the lead in that terminal and move the negative result in the other terminal. In case you see battery voltage with each leads related to the electrical connector, that confirms the compressor snatch is getting electricity and ground. That means the clutch coil is awful. A few clutches are replaceable, others aren’t and also you ought to update the whole compressor. Engine off. Disconnect the electrical connector at compressor grasp. Set meter at dc volts. Join high quality cause one terminal in snatch electric connector (1) , terrible lead to battery floor. Start engine with a/c turned to max. Search for battery voltage on meter. If voltage is 0, pass tremendous cause the alternative terminal in electric connector. If nonetheless 0, proceed to step 2. The pcm will now not offer floor to the compressor relay if the device is low on refrigerant or the pressure in the machine is simply too excessive because of a blocked condenser, terrible orifice tube or tmx valve. Discover the low stress and high stress switches. With meter still set on dc volts, disconnect the electric connector on the low stress switch. Join the superb result in one terminal and the negative lead to the opposite terminal. Begin the engine and flip the a/c to max. Search for voltage on one of the two terminals (5). In case you see volts, which means the pcm is presenting strength. Do the identical take a look at on the excessive pressure transfer 5). Of electricity is gift at both switches, behavior a continuity take a look at across the switch contacts step 4.
