If you have no speeds at all, including high speed and you have power at the fuse and the fuse is good, I would suspect the heater blower speed switch and or the electrical plug to the switch is cooked. If you have high speed only and the rest are dead, I would suspect the blower motor speed resistor.

If you have no blower speeds at all, first check the fuse. If the fuse is okay I would suspect the blower speed switch and its electrical plug has melted. If the switch checks okay I would suspect the blower motor is bad. If you have high speed only, I would replace the blower motor speed resistor. If you have all lower blower speeds but no high speed, replace the high speed relay.
