Hi All,
Fringle, my '94 855 is having some AC troubles.
AC is generally working well, but for some reason the radiator fan is not turning on when the AC is turned on.
Am I right in thinking this should come on all the time ?
I've seen some posts about people saying sub 32F the fans dont come on, but I'm in Australia (Sydney) and it never gets that cold.
Any suggestions on what might cause this.

Re: Radiator fan not coming on with AC
There are a couple of things that come to mind. The most common is a bad fan relay and it can be tested fairly easily by individually grounding the relay pins associated with the yellow and the yellow/white wires on the center connector of the relay. One will turn the fan on at low speed and the other should turn it on at high speed. The fan relay is fairly cheap and it is very easy to change. The relay is on the fan shroud and I think it is still on the left side of the shroud even on a left hand drive car.
The other possible culprit, assuming that the AC is indeed functioning properly, is the high pressure switch on the AC system. The switch is expensive but they usually don't go bad. I have picked up used ones at a Pick-N-Pull and they always have worked.

Re: Radiator fan not coming on with AC
thanks, I'll look into it. I have a feeling I might have a spare fan relay.
