Car air conditioner wiring diagram - In case you see battery voltage on one terminal, leave the lead in that terminal and circulate the terrible cause the opposite terminal. If you see battery voltage with both leads linked to the electric connector, that confirms the compressor take hold of is getting energy and floor. Which means the clutch coil is awful. A few clutches are replaceable, others aren’t and you have to update the entire compressor. Locate the compressor grasp relay and eliminate it from its socket. Connect the negative meter cause battery negative terminal. Probe the relay socket terminals to locate battery electricity at terminals 2 & 3. If you don’t see battery voltage on both terminals, take a look at the fuses and wiring to the relay. If you have battery power on both terminals, connect the fine lead to terminal 3 and the negative cause terminal 4. You must see battery voltage. In case you don’t, the pcm isn’t supplying ground to the relay control coil, flow to step three.

Engine off. Disconnect the electric connector at compressor grab. Set meter at dc volts. Connect positive cause one terminal in take hold of electric connector (1) , negative lead to battery ground. Begin engine with a/c became to max. Look for battery voltage on meter. If voltage is 0, flow nice lead to the other terminal in electric connector. If still 0, proceed to step 2.

The pcm will now not provide floor to the compressor relay if the system is low on refrigerant or the stress in the machine is just too high due to a blocked condenser, terrible orifice tube or tmx valve. Find the low stress and excessive stress switches. With meter nonetheless set on dc volts, disconnect the electrical connector at the low strain transfer. Join the high quality lead to one terminal and the bad result in the opposite terminal. Begin the engine and flip the a/c to max. Search for voltage on one of the two terminals (five). In case you see volts, which means the pcm is offering electricity. Do the identical check at the high stress switch five). Of power is gift at each switches, behavior a continuity test across the switch contacts step four. If the a/c in your automobile isn’t running, step one is to see if the compressor runs when the activate the a/c and the engine. In case you find out an ac compressor won’t run situation, comply with these diagnostic steps to discover what’s incorrect. You’ll want a virtual multimeter and a wiring diagram or elements locator to find the high and occasional strain switches.
