2014 Q7 TDI ACnot working
 

Hi, My 2014 Q7 TDI AC was working till yesterday night. This morning, when I press AC switch, the red light on switch comes momentarily and then goes off. Ac does not come on. No sound of fan or rpm change. Any idea what to check.

I would post this in the Q7 forum, it will get a lot more traction there....
