The fan itself could be defective also. You are supposed to jumper the wires to the battery to check it. The easiest to check first is the 50 amp fuse box near the battery but you need to disconnect the battery first if the fuse does not visibly look broken if that makes sense. Otherwise disconnect battery, disconnect fuse and take a close look at it.
