Bought a 2002 s60 w160k three weeks ago. Thought I had checked it out pretty well. Ac was blowing cold. 1 week later, blowing hot. Pressure gauge shows good charge. Took it to an auto ac guy. He diagnosed ac/rad fan not pushing cold air. Ordered new oem fan, but when it arrived, did not have controller assembly as the original did. Sent it back and ordered another. Same thing. No controller assembly. I have no clue as to what I should do. Any constructive criticism is welcome.
