If you see battery voltage on one terminal, leave the lead in that terminal and circulate the negative lead to the other terminal. If you see battery voltage with each leads related to the electric connector, that confirms the compressor grasp is getting electricity and floor. Which means the grab coil is bad. Some clutches are replaceable, others aren’t and also you need to update the complete compressor. If the a/c for your automobile isn’t working, the first step is to peer if the compressor runs whilst the turn on the a/c and the engine. In case you discover an ac compressor won’t run state of affairs, observe these diagnostic steps to find out what’s wrong. You’ll need a digital multimeter and a wiring diagram or components locator to discover the excessive and low strain switches. The pcm will no longer offer ground to the compressor relay if the machine is low on refrigerant or the stress within the system is too high due to a blocked condenser, horrific orifice tube or tmx valve. Discover the low pressure and excessive pressure switches. With meter still set on dc volts, disconnect the electric connector on the low strain transfer. Join the tremendous lead to one terminal and the bad lead to the opposite terminal. Begin the engine and flip the a/c to max. Look for voltage on one of the terminals (5). If you see volts, meaning the pcm is offering electricity. Do the identical take a look at on the high stress transfer five). Of energy is gift at both switches, conduct a continuity check throughout the transfer contacts step four.
Find the compressor grab relay and get rid of it from its socket. Join the bad meter cause battery terrible terminal. Probe the relay socket terminals to detect battery electricity at terminals 2 & 3. If you don’t see battery voltage on both terminals, test the fuses and wiring to the relay. When you have battery electricity on each terminals, connect the advantageous lead to terminal 3 and the negative result in terminal 4. You should see battery voltage. In case you don’t, the pcm isn’t presenting ground to the relay manipulate coil, circulate to step 3. Engine off. Disconnect the electric connector at compressor snatch. Set meter at dc volts. Connect advantageous result in one terminal in seize electric connector (1) , bad lead to battery floor. Start engine with a/c turned to max. Search for battery voltage on meter. If voltage is 0, flow high-quality cause the other terminal in electric connector. If nevertheless 0, continue to step 2.
