I had this same problem with my '02 Ram .. Dealer wanted around $300 for a new fan/shroud/labor ... I declined, bout the fan myself, decided to try the fan prior to installing it, the fan didn't work .... 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 :-)
