It sounds like theres a wiring shorting out. If not, maybe it's something in the plugs? Might even be internal to the motor...

could it be the relay?

Try unplugging the wires going to the blower motor, then turn it on. If its a problem internal to the blower, or a short on the negative side, you shouldn't be blowing a fuse anymore.

If the fuse still blows with the wiring disconnected, then you've got a short somewhere before the blower motor.
