Can I service the ride control compressor myself? Where is access? on 2006 GMC Yukon XL Denali

Service Ride Control light just popped on week or so ago. I do not hear the compressor kick on when vehicle is first started like it normally did. Any chance this could be a simple fuse problem? Our purchasing dealer was one that was closed by GM, now closest is 30 miles away.
