Resolved 2G A/C system not working

[cswindel]

Alright electrical nerds I need to be graced with you assistance as I am no good with electrical.

Current situation:
- A/C is not blowing cold air although the system has been charged recently without the system actually pulling in r-134 because well it dont work haha
- I dont have any prior knowledge of whether it worked or not before or after my teardown of the car
- As a side note I am running OHM harnesses throughout the engine bay and interior and running ECMLink v3

Current untested areas and possible theories:
- A/C compressor is dead and I have not ran 12v power to it such that I can test if the clutch engages or not
- Seeing if there is a setting in ECMLink that I am missing since the a/c and rad fan both kick on when signal for rad fan to kick on gets pushed out
- Thermo sensor is poop but havent checked and the wiring diagrams confuse me on where it is physically located behind the glove box and there arent really any pictures when i look.
- ACCU is poop but havent checked and not sure which wires in the connector to check but havent dug into that area yet because its a pain to reach

Steps I have taken thus far:
- Checked continuity from ECU pin 22 to A/C compressor relay in fuse box (Good continuity)
- With key in ON position and engine not running, I have voltage going to the a/c fan (connector A-39), Dual pressure switch (A-47), and the A/C compressor (A-95)
- With the engine running I checked for voltage at the same connectors and nothing concerning
- With the engine running and a/c switch active I checked voltage again and still nothing concerning. A/C compressor ground showed grounding too.
- With the engine running, I jumped/bypassed the dual pressure switch and no result came about from that
- As mentioned prior, I noticed that the a/c fan and rad fan kicked on at the same time when the signal for the rad fan got passed through the circuit (I dont know if this is normal or not but hey 2 fans is better than 1).

Just wanting to see what your inputs are with this matter before I start going down unnecessary rabbit holes without much guidance (because I will get lost, sad, and confused and it might all occur simultaneously). I believe I have covered the majority of what I have done and assessed to get this thread rolling at least

I just want to note that helping digitally through a forum is more than what OHM who sold the product will ever do. Thank you @Vladimir for being on this forum with your knowledge and experience for the love of the game and figuring out issues.

Absolutely without a doubt. I honestly owe a lot to the people on this forum. It's actually a big reason why I love the car so much is because of the community. And I mean it when I say @Vladimir you have been my saving grace

Im glad I can be helpful to a fellow DSMer... It's a challenge tho...this harness. There was multiple things wrong to begin with, both mechanically and electrically. I've seen a lot of techs, even some guys with a lot of experience struggle when it comes to wiring schematics and this wiring issue is 10 times worse... Not only are the wires all wrong color, they are also routed differently, not according to the diagram.

I am genuinely surprised that OHM doesn't provide a digital copy or at the very least a paper copy for their new custom wiring harness... I understand they are specialized builds but how is anybody who is not an ASE certified tech gonna figure this out.... Maybe OHM should add an option for additional $$$ they can create schematics for what they've done.

Im surprised mostly by how Cliff actually followed through with all the testing...99% of non techs would have probably just give up already. That's definitely impressive.

This forum helped me many times and everyone is always friendly and respectful....I just give back what I receive... And I do genuinely believe DSM community is the most welcoming and easy going.... I had toyotas, porches, Subaru and Nissans to compare with... Toyota guys are pretty cocky in my area and think they know it all, not sure if it's just in Illinois
