Im trying to get this system working correctly, but not sure I even know what that really means lol
I had a service suspension DIC and had the codes pulled. One was the exhaust valve that usually means a corroded wire. Found it, and replaced/temporary fixed it last night around 11pm (Had to be up by 4:30 not real thrilled)
Anyway, the compressor now fires up and runs, but didnt have time to do much testing. I did however need to verify the trailer brake controller worked since my cruise/brake switch is bad. They didnt, so thats another project.
BUT, I backed the rig under the trailer, went, had a beer, then lowered the trailer onto the hitch ball with the vehicle off. I started the yukon, got all excited when the compressor kicked on, ran for a bit, 30 seconds maybe? but never seem to actually lift or level the truck. Thats not normal correct? Usually the compressor has enough balls to pump enough PSI to level the yukon even under heavy loads? (Its actually a pretty small RV trailer considering).
What really throws me is that the rear shocks and front struts seemed to be replacements, they are label BWI though, which seem to just be an OEM supplier. With that said, they still have an air line running to them so they are non-air ride replacements. The rear coils are also replacement and with the shock still being air-ride why would they replace the coils? I was under the impression the coils were only replaced when going to non auto ride setup?
Also, something else interesting, everything I read said this body style has the compressore behind the passenger wheel, while the older body style was behind drivers rear wheel. Mine was behind the drivers rear wheel, is this an early 07 model year thing?
