Oh also bought a relay as the dealer said I would need as well...replaced the relay and plugged in new fan .. nothing worked .... sure enough, I checked the fuse and bingo.. so it ended up being a .17 fix and a lot of trouble by listening to the stealer ... anyway, I also learned later that in the winter, water can get in the shroud and freeze the fan, locking it up and popping the fuse .... to fix that problem, drill a few hole in the bottom the shroud allowing water to drain and not freeze.. Or carry more fuse's :-)
Did the problem ever come back? What other issues may cause the fuse to blow? I live in Southern Cal so any water freezing in the shroud is unlikely. Since you have a new fan do you think your old fan motor may have caused the blown fuse? I'm having the same problem and my fuse was blown also. I replaced it and now it works but I'm not sure if I trust it. Shouldn't there some reason why a 25amp fuse will blow? Can a fuse blow without a problem? Sorry for all the questions, I just want to get this corrected before the hot summer months.
