Mine was blowing out hot air. Started slowly getting less and less cold until it actually felt hotter come out of the vents with the aircon button pressed than it did with just the fans blowing. I drove to London from Scotland on the hottest day of the year this year and Me & the wife melted. Popped into Kwik Fit on the way back to get it regassed and it was instantly ice cold like new. Like was said earlier, £49 and if it's not noticeably different (I think they say at least 10 degrees cooler) you don't pay a penny. Simple, quick fix.
