If you find out an ac compressor received’t run situation, comply with those diagnostic steps to discover what’s wrong. You’ll need a digital multimeter and a wiring diagram or components locator to find the excessive and coffee strain switches. Engine off. Disconnect the electric connector at compressor clutch. Set meter at dc volts. Join effective result in one terminal in grab electrical connector (1) , poor lead to battery floor. Start engine with a/c grew to become to max. Search for battery voltage on meter. If voltage is 0, circulate effective cause the opposite terminal in electric connector. If nonetheless zero, proceed to step 2.
Discover the compressor grasp relay and remove it from its socket. Join the poor meter cause battery negative terminal. Probe the relay socket terminals to hit upon battery electricity 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 power on each terminals, join the nice lead to terminal three and the terrible result in terminal four. You should see battery voltage. If you don’t, the pcm isn’t offering floor to the relay manage coil, flow to step 3.

In case you see battery voltage on one terminal, depart the lead in that terminal and flow the poor result in the alternative terminal. In case you see battery voltage with each leads related to the electrical connector, that confirms the compressor seize is getting energy and floor. Meaning the grasp coil is horrific. A few clutches are replaceable, others aren’t and you should replace the entire compressor.
