Good point. Let me add a little bit more to this though. I have found out that the fuse only burns out when I turn on the A/C. My A/c doesn't work anyway. However, the aux fan turns on when the a/c is on OR when the ECU decides it should go on for another reason (which, I presume, would be when my coolant temp reaches 222). SO, apparently, the ECU is NOT turning on the aux fan on its own. Or maybe... it can't. There are two relays for the aux fan. One is for low, the other high. But how these work for a single speed slim-line fan, I have no idea. Is there a separate fuse for the other relay? I can't find it in my fuse box. Azdave says fuse 9 applies to aux fan in an old thread, but I don't know where that is. The 20a fuse that pops is a tiny blade fuse, unlike the huge fuse I see for the driver side main fan.

now... where is that fsm...
