I've got two fans, a separate fuse for each. They're in the fusebox in the engine compartment. It's one of the large fuses, in my case they're yellow and AFAIK 40A each.
Thanks for the info... However, the problem I have is when I look in the fuse box I dont know what any of the fuses are for - I can see some 40A and 60A fuses but there are also about 10 fuses missing but obviously I dont know if they are supposed to be missing so chances are my fan may not work because the fuse is missing! lol
