Hello, my name is ***** ***** I'm here to help get your problem solved.

The height sensors built into the shocks tells the electronic suspension module when to activate the compressor. It sounds like problem is either height sensor or suspension module but to know for sure a scantool capable of monitoring everything will be needed. This isn't really a system you can work on from home unless it is a obvious problem. I'd expect repair to cost around $600 at dealership give or take a couple hundred depending on the problem Let me know if you have questions, thanks.
