Probably a bad blower motor resistor
I would suspect the blower motor speed resister is shot.
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
Most likely cause is a failed blower resistor.
The blower motor speed resistor is burned out. The resistor is usually found close to the blower motor. Auto parts stores carry that part and it is easy to replace.
either the control head is bad or there is a blower motor resistor that is bad.
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
The blower motor speed resistor is burned out. The resistor is located close to the blower motor and is easy to change. Your local auto parts store will have that part for you.
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse.

The resister for the 2001 prism blower motor drops voltage to the blower motor. This is how the blower motor runs at a lower speed.
Resistor on the heater blower motor has failed
yes indeed
