This sympton is more an indicator that the water has got into the blower motor and siezed it. In that condition the inrush current is so high the feed fuse blows whatever speed.
Disconnect the motor and unscrew the retaining screws fron inside the footwell, drop it out and check if it is stiff or turns at all.
