I have a 1999.5 audi a4 and I just put a brand new AC belt on and I had my air conditioner re-charged but I still do not have cold air. Its more like a cool fan instead. I was wondering what else could be the problem. There is no leak because when I had my AC recharged there was still alot left inside. If anybody knows what it could it be that would be a great help. Thanks.

It might be a very slow leak. Something that you wouldn't notice right away. If you can gain aceess to a lift or know somebody that does work to your car, have them add some dye to the system to check if their is infact a slow leak. if not it may be your evaporator, and that im sorry to say is a pain is the a$$ job to replace.

Could be the temp blend door not going to full code, VAG might tell you that or you can search for the HVAC codes online i think its on audiworld.com. If its blowing cool air on a hot day but not cold and you know its not leaking thats what its probably gonna be.
