Hi everyone,

My A4 air conditioning is not in tip top condition it would appear. When I bought it, it never blew cold air so I just assumed a re-gas was needed, so this was done this weekend and completely filled. Now it is blowing slightly cold air but only through the middle vents and not the passenger or drivers side.

So my questions are:

1) What to trouble shoot?
2) Why wouldn't it be blowing cold air?
3) What would stop it blowing this cold air out of the side vents?

I should probably point out all the vents work as they should when the air-con is not on.

Thanks!
