Hello all, I'm hoping you guys can help me with a problem I'm having with my 2004 GMC Denali. When I hook up my car trailer the compressor kicks on and runs for about 5 to 10 min but the truck doesn't level out after sinking 3 inches. I don't get any error message ether. I'm thinking it might be a leak somewhere. Like I said the compressor kicks on and run for about 5 to 10 min so I don't think it's the compressor. I only hook up my car trailer about 2x a year. Last time it worked great. The compressor went on and the truck leveled out. This time the compressor went on but the truck didn't level out. Any ideas????

Either the compressor isn't putting out any air or the shocks are bad..Arnott industries has replacement compressors and Bilstien air shocks for the rear. Prices are much better than dealer or monroe's prices. It is still expensive.
