I have a 2009 Yukon Denali Xl. For the past few months the Autoride compressor has been super noisy and running constantly. 2 weeks ago, I decided to replace the rear shocks with Arnott rebuilt units. After replacing the compressor was still noisy which is knew it would be, but it would run as normal and shut off quickly. Speed up to this week, old compressor stopped working. replaced with a new Dorman unit yesterday. Started the truck up, compressor kicked on as normal for 5 seconds then shut off. Drove around a bit, came home then one more time turned truck off, then back on to test and compressor kicks on for 5 seconds and turns off as normal. Later that night and today, compressor does not run at all. I have checked all fuses and continuity is good.
Here is my testing so far:
Fuses: 58, 2, and 54 are good and continuity is good.
I can power the relay from pins 86 and 85 and the relay clicks.
I have constant power on pin 30 on the relay connector
If I jump connector spots 30 and 87 the compressor runs.
Please help with any ideas I might be missing, from my testing all checks out but for some reason the compressor wont kick on at start up anymore. I also put a full load of groceries in and filled with gas last night and it does not kick on either.
Thanks for your time
