I have a 2006 SC. I am down to the bump stops. I get error messages like: Vehicle raising slowly, suspension failure do not exceed 30 mph, vehicle will continue to raise when system cools, and slow down or vehicle will lower. I am thinking it has to do with the compressor or a leak in one of the lines. What are some of the things I can do to diagnose and pinpoint what is causing my RR suspension problems? I read there is a brass muffler on the compressor. This could be clogged and cause the problem. Has anyone had any luck removing this and correcting this type of issue. Thanks in advance for any help.
