Someone's help would be greatly appreciated, i commute to school and it was 38 degrees this mornin and I had no heat! The controls all work but I think the main switch valve to go from A/C to heat is stuck, so could someone explain or tell me or show me a pic of where it is so I can just turn it to heat so I dont freeze my a$$ off anymore? it's getting colder so please help guys!
its a 96 A4
