What causes AC to quit and ABS, anti-slide and EDS warning lights come on? on 2007 GMC Envoy

AC will quit blowing air by adjusting fan knob on occassion. Sometimes it just quits on its own. AC will come back on if you restart the car most of the time but not always.

sounds like the body control module. you need to have it checked for codes and operation. no free codes on this one. you need a real shop, real tech and a real diag to get to the source of the problem.
