So, my comp grenaded on me. I bought a used replacement, but waited until the hotter months to bother fixing it. I finally slapped it on, new accumulator as well, and when charging it up, I can't get it to kick on.

So, after some searching I found the FSM and spent hours trying to go through it to see if I could find the connector specs to test the circuit to make sure it's getting signal. Can't find it anywhere. I do the self diagnose test and that gives me no information, I check for the relay and it doesn't have one. So that leads me to believe it's either the switch or something else entirely.

I rockauto a switch, and still nothing. So I'm left out in the dust. I'm not always good with Technical manuals if they don't give consistent and objective ways to find the information and working in Nissan parts before, I know they don't always use the most logical part names. So if anyone could help me out it would be great.

I'm hoping I don't have to spend the hundreds it'll take to go to the Infiniti dealer to have them figure it out. I unfortunately don't have the thousands of dollars worth of tools to do much more than circuit checks. So if you know where I can get the data for any of the connectors, it would be a huge help. Thank you.

Have you checked for blown fuses?

Good luck

Assuming you vacuumed the system and recharged it or atleast have pressure in the system. Hook a test light in place of the clutch, start the car and turn on the a/c. Its not uncommon to have a bad clutch. My clutch failed with an open coil earlier this summer. I had power to the clutch but no clutch operation. I ohmed the clutch coil and it was open internally. Make sure you plugged the pressure sensor back in on the drier.
