Does the VX have a climate control specific built-in fault finding system like the VR-VS does? / Why are my vents not working?

Thank you @Lex, @lout and @krusing for your suggestions. The heater control hose had come off the back of the plenum. Air is once again flowing from my vents, my fingers will remain toasty warm when driving, order is restored.
