Is a blower motor and a blower motor resistor the same thing?

The blower motor switch is the actual switch or button on the dash that you use to increase or decrease the fan speed. The blower motor IS the fan. The blower motor resistor is what allows the fan to work at different speeds as opposed to just off and on.

What happens when blower motor resistor goes bad?

If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.
