2006 Kia Sorento. Ac was working . good and cold. Went inside and came back out no ac. Have tested lines and its not low on r34. No power to high pressure switch. Never found a low pressure switch. I have what it call C fan 2 and the auto parts store calls it a ac selector relay. I have power at the relay and with a test light can make the ac fan kick in. There is not a second relay to swap out with to test. How can I test this relay ? Is there something else I can check? No one has the relay in stock so I would have to pay as much as the relay cost just to get it here. Thinking of junk yard for a test relay. What else should I check?
