Morning,

Air seats- Compressor runs constantly, shut her down and listened at bottle...air leaking from small pressure relief valve...to GMC Med duty shop here in Houston..they give me a longer one ..drained tank and tefloned the new one, re start fill tank, relief valve works but Damn..sounds like the truck needs GAS-X. Compressor continues to run despite full tank.
Any one else having similar problems. post ur solutions.
Thanks

P.S found out the $31.00 valve is for air-brake system, cant find OEM valve
