Car ac wiring diagram - The pcm will not offer ground to the compressor relay if the gadget is low on refrigerant or the stress inside the gadget is simply too excessive because of a blocked condenser, horrific orifice tube or tmx valve. Locate the low pressure and high strain switches. With meter nonetheless set on dc volts, disconnect the electric connector on the low stress transfer. Join the advantageous result in one terminal and the terrible cause the opposite terminal. Begin the engine and flip the a/c to max. Search for voltage on one of the terminals (5). In case you see volts, which means the pcm is providing electricity. Do the equal test on the high stress switch five). Of energy is present at both switches, behavior a continuity take a look at across the switch contacts step 4. If you see battery voltage on one terminal, go away the lead in that terminal and flow the terrible result in the opposite terminal. If you see battery voltage with each leads linked to the electrical connector, that confirms the compressor take hold of is getting strength and floor. That means the snatch coil is horrific. A few clutches are replaceable, others aren’t and also you need to replace the entire compressor. Engine off. Disconnect the electrical connector at compressor seize. Set meter at dc volts. Connect advantageous cause one terminal in grab electrical connector (1) , negative result in battery floor. Start engine with a/c became to max. Look for battery voltage on meter. If voltage is zero, pass tremendous result in the other terminal in electric connector. If nonetheless zero, proceed to step 2. If the a/c to your car isn’t operating, the first step is to look if the compressor runs whilst the activate the a/c and the engine. In case you discover an ac compressor gained’t run scenario, follow those diagnostic steps to discover what’s incorrect. You’ll need a digital multimeter and a wiring diagram or elements locator to locate the excessive and occasional strain switches. Find the compressor grasp relay and take away it from its socket. Join the bad meter cause battery negative terminal. Probe the relay socket terminals to hit upon battery energy at terminals 2 & three. In case you don’t see battery voltage on each terminals, take a look at the fuses and wiring to the relay. If you have battery energy on both terminals, connect the positive lead to terminal 3 and the poor cause terminal 4. You ought to see battery voltage. In case you don’t, the pcm isn’t providing ground to the relay manipulate coil, circulate to step three.
