HEAT NOT WORKIN BLOWIN OUT COLD AIR WHAT SHOULD I DO?
Check to see if it is low on antifreeze. Blend door may not be switching in the dash from cold to hot air.
did you ever have anything like water pump replaced or radiator, or timing belt replaced. if thats the case your system may not have been bleeded properly its a very comman issue in audi's and vw's the antifreeze ends up with air pockets and makes it so the heat does not work.
