Resolved "Service Suspension System" Problem

[b-mccullough]

Service Suspension System showed up about 6 weeks ago. - Replaced the rear compressor with a Dorman unit for $244. I am assuming it is acting like it is supposed to. The warning message is gone and when I start the Tahoe after about 10 seconds it runs for about 5 seconds. Is there anyway to test the system to know if it is doing what it is supposed to?

Thanks for any advice. It is on a 2008 LTZ.

I have the 07 LTZ with the same system. Also replaced the rear compressor. When I hitched my horse trailer, I could hear the compressor kick on and run and could see the vehicle level up. Try weighting the back end..........

Thanks.the new one seems louder than the original. How about yours?
