There was a recall on some 2014 or 2015 Vegas for the switch that controls the defroster. In mine, the switch broke with the defroster in the defrost position. I was in Alaska at the time and was able to disconnect the flap that engages the defroster - located in a box underneath the passenger side of the dash. Then I had heat and A/C bug no defroster. With that switch in the defrost position, all the heat and A/C came out at the bottom of the windshield.
