How do you replace a heater resistor?
- Remove the negative battery terminal.
- Locate the blower motor resistor on the passenger side under the dash board.
- Disconnect the electrical connector to the blower motor resistor.
- Remove the screws or bolts to the blower motor resistor and remove the resistor.
- Installation is the reverse of the removal.

Simply so, how do you test a heater resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.
Similarly, where is the heater blower resistor located? It's located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.
In this manner, what is a heater resistor?
The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor's fan speed. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.
How much is a blower motor resistor?
The average cost for a blower motor resistor replacement is between $119 and $161. Labor costs are estimated between $47 and $60 while parts are priced between $72 and $101. Estimate does not include taxes and fees.
