my experince with the a/c with my S70 1997 yes manufactured in 4/1997
soon as you switched on the a/c , it is a ECC unit , the recirculate and a/c off LED flashed for 20 seconds, the a/c not working at all no fan nothing what so ever but you can hear the compressor cycling on and off. Took it to the local mechanic and regassed the unit . It was working again but not the next day, so off I went straight to the dealer as the mechanic would not be able to help any further. Spent close to $1000 australian to fix and it was the fan motor drawing too much current tripping the guard circuit. They did not explain why but I guess replacing the fan is the way they went about to fix it.
