What kind of resistor does a heater blower use?
Types just controlling the fan speed generally just comprise of a few wirewound power resistors (or one resistor with a 3 or 4 windings), which have the effect of regulating the motor speed by reducing the voltage available to the fan. These types always include a thermal trip, which will permanently blow if the rated temperature is exceeded.
Why is my heater blower motor resistor not working?
This occurs due to the failed blower motor resistor not being able to control the flow of electric current, it could be that the resistor is somehow bypassed and the power is directly being fed from the switch. Excessive current can overheat and permanently damage the blower motor resistor

How can I tell if my blower resistor has burned out?
Find the blower resistor and detach it from the rest of the circuit, Once the resistor is positioned and detached, it is often possible to say whether or not the resistor has burned out or not judging by simply looking at its condition. A burned out resistor needs to be replaced via the correct alternative.
What are the symptoms of a bad blower motor resistor?
Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. Blower motor does not work on certain settings. No air from the vehicle’s vents.
Where is heater blower motor rsistor located?
The heater blower motor resistor is located underneath the dashboard in the heater/AC compartment. The resistor enables the heater blower motor to change the speed of the fan.
Where is the fuse for the heater blower?
The blower motor fuse should be a 30 amp located in the passenger compartment just to the left of where the driver sits, underneath the dash above the left kick panel. It should be marked blower.
What does a blower motor resistor do?
Definition. A blower motor resistor, typically located beneath the passenger side dashboard, contains three resistors, or sets of terminals designed to generate voltage in proportion to electrical current. These resistors allow the blower motor to function at lower speeds.
