Hey Eric, I appreciate the reply. Yes, agreed. I didn't mention that specifically, but that was definitely part of it. The service manual had me check continuity on various parts of the circuit as well as voltage being supplied when the ignition was on. Basically the compressor runs on 2 circuits, bound by a relay. You have a circuit that has the dual-pressure sensor -> A/C switch -> Fan switch -> ground, and you have a circuit that runs to the compressor -> ground that is only complete when the first circuit completes. The service manual has you systematically check that 1) each circuit has voltage, and 2) that there's continuity between each link. It was only when I found that there was no continuity between the dual pressure sensor and the A/C switch, is when I broke out the short detector and ran it along the wire to find the breakage. It was a good learning experience since I had never dove into electrical issue diagnosis. I know its mentioned a bunch in this forum that has been so helpful to search, but NICO club has the service manuals for pathys. https://www.nicoclub.com/nissan-service-manuals Between that in searching here I've been able to DIY pretty much everything since I bought my R50.

Thanks for taking the time to update us on the solution. It may help someone at some point. If you have a multimeter you can also find open circuits by measuring resistance and/or continuity, just in case you already have one.
