So I get the first chill in NY last night......I just got the car about 2 weeks ago and so far no need for heat. I put the heat on and only cold air comes out and no air is coming out from the front defrost (winshield). Can some of you experts help me out? 1993 AUDI 100 S. (THANK GOT FOR HEATED SEATS!!!!! it was the only thing that kept me warm)
