Hankshanker, I too would like to know the link between the AC and the PS fan. I have a couple of theories that might possibly explain the connection...
One, it could be that the fan is actually dual-purpose, serving as both PS fan and an "auxilliary AC fan," though I don't know anything about AC systems so i don't know how likely that would be. Never heard mention of it before, though, so it seems a bit strange.
My other theory is that the PS fan stopped up, blowing the fuse, which then shut down the cooling fan. The car sensed that it was getting too hot and therefore would not allow the AC to run, since that would only make the engine work harder and create more heat. The problem with that theory is that if it was warm enough that you needed your AC on and your radiator fan wasn't working, it seems like the car would have overheated pretty quickly, whereas didn't this problem last quite some time for you? Do you have a temp gauge, or do you have the nav? If you do have the gauge, did you notice excessive heat (i.e. more than halfway) buildup?
