Latest auto ac compressor wiring diagram - Engine off. Disconnect the electric connector at compressor take hold of. Set meter at dc volts. Connect nice lead to one terminal in snatch electric connector (1) , poor result in battery ground. Begin engine with a/c turned to max. Search for battery voltage on meter. If voltage is zero, circulate high-quality cause the alternative terminal in electric connector. If nevertheless 0, continue to step 2. Find the compressor grab relay and put off it from its socket. Connect the negative meter lead to battery poor terminal. Probe the relay socket terminals to detect battery power at terminals 2 & three. If you don’t see battery voltage on both terminals, check the fuses and wiring to the relay. If you have battery electricity on each terminals, join the high quality lead to terminal three and the poor result in terminal 4. You have to see battery voltage. If you don’t, the pcm isn’t providing floor to the relay manipulate coil, move to step 3.
In case you see battery voltage on one terminal, go away the lead in that terminal and pass the poor lead to the alternative terminal. In case you see battery voltage with both leads connected to the electrical connector, that confirms the compressor seize is getting strength and floor. Meaning the grab coil is bad. Some clutches are replaceable, others aren’t and also you need to replace the complete compressor.

If the a/c on your vehicle isn’t operating, step one is to see if the compressor runs when the turn on the a/c and the engine. In case you find out an ac compressor gained’t run situation, observe these diagnostic steps to discover what’s wrong. You’ll need a virtual multimeter and a wiring diagram or elements locator to find the high and occasional stress switches. The pcm will not provide ground to the compressor relay if the machine is low on refrigerant or the stress inside the gadget is just too excessive because of a blocked condenser, horrific orifice tube or tmx valve. Locate the low stress and excessive strain switches. With meter still set on dc volts, disconnect the electric connector at the low stress transfer. Connect the wonderful cause one terminal and the negative cause the other terminal. Begin the engine and turn the a/c to max. Look for voltage on one of the two terminals (five). In case you see volts, that means the pcm is offering strength. Do the identical take a look at at the high pressure switch five). Of energy is gift at each switches, conduct a continuity take a look at throughout the transfer contacts step 4.
