How do you know if your heater resistor is bad?
Symptoms of a Bad or Failing Heater 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 the heater blower resistor located?
The heater blower motor resistor is often found beneath the dashboard. It is located in the heater and air conditioning compartment. It’s connected to the air conditioning system, where it can adjust the speed of the blower motor fan.
Where is 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.
Can you repair a blower motor resistor?
The resistor module is easy and inexpensive to replace. It’s then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25).
How much does it cost to replace a blower motor resistor?
The average cost for a Blower Motor Resistor Replacement is between $108 and $137 but can vary from car to car.
Is there a fuse for blower motor?
The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle.
How do you diagnose a bad blower motor resistor?
If the airflow from the vents is weak… If you try to increase the air pressure and you feel no difference in the pressure blowing, then your blower motor resistor may be failing. A damaged blower motor resistor will work on one fan speed which may not be enough to keep the inside of your car cool or warm enough.
What causes heater resistors to burn out?
Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life.
What are the signs of a bad blower motor?
5 Signs Your Blower Motor Needs to Be Replaced
- Weak Airflow from the Vents. This is usually the first indication that you may have a faulty blower motor.
- No Airflow at All.
- Unusually High Energy Bills.
- Strange Sounds.
How long does it take to replace a blower motor resistor?
takes about 45 minutes.
