I've been driving the car and the AC has been working just fine, blowing ice cold. Today when I came out of walmart I got in the car turned it on the ac light was on and the ac was blowing just fine and when I switched the ac from blowing from my feet to my face the circulation light and the ac light both cut off and no air would come from the vents.

 

so, the AC works fine only when its blowing your feet? what about when the ac is off? the ventilation works?

 

check your fuses. sounds like you blew one
