I don't believe there is a fuse for the blower motor. I think it is a self resetting breaker. The relay for it is in the power distribution center under the hood. All of the relays in that box are the same. So to test it, remove the one for the blower and replace it with one of the other ones and see of the blower works. If that doesn't do it then you will have to do some more extensive trouble shooting.
