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 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.
Where is the blower motor resistor on a 2014 Chevy Cruze?
The blower motor resistor is up in the dash towards the left. It has two connectors on it and is held in with two screws.
Where is the blower motor located on a Chevy Cruze?
The blower motor is a fan located in the heating ventilation and air conditioning (HVAC) ducts, usually behind the glove box.
How do I know if my blower motor resistor is out?
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 happens when a 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.
How do you remove and replace a blower motor resistor?
How to Replace a Blower Motor Resistor
- Step 1: Remove the glove box door, if necessary. …
- Step 2: Disconnect the wiring harness and remove screws. …
- Step 3: Remove and replace the blower motor resistor. …
- Step 4: Tighten screws and reattach wiring harness. …
- Step 5: Reinstall the glove box door.
Where is the blower motor resistor on a 2013 Chevy Cruze?
The heater blower motor resistor is located underneath the dashboard in the heater/AC compartment.
Why is my Chevy Cruze blowing cold air?
If you engine temperature gauge is reading too low this could indicate the thermostat is sticking open and not allowing the engine to reach operating temperature. You could also be having an issue with a blend door actuator or door. These are located behind the dash and control air flow.
How do you test a blower motor 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.
Where is the heater blower motor located?
The blower motor is usually under the dashboard on the passenger side. Blower motors that make loud squeaks or rattling noises may be worn out and on the verge of packing it in, but sometimes those noises are caused by leaves or other debris that can be cleaned out after the motor is removed from the vehicle.
What is the blower motor?
A blower motor is a component within an HVAC system that is responsible for circulating air into the building. It’s the key to maintaining a comfortable temperature and humidity throughout your facility. Blower motors push cold air (in the summer) or hot air (in the winter) through ducts to the desired locations.
Is there a fuse for the blower motor?
To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash. The rating of the fuse will depend on the vehicle application and how much power the blower motor requires at full speed.
How much does it cost to replace a blower motor resistor?
The average cost for blower motor resistor replacement is between $109 and $140. Labor costs are estimated between $44 and $55 while parts are priced between $65 and $84. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
What are the symptoms of a bad blower motor?
What Are Signs Your Blower Motor Needs to Be Replaced?
- Poor or Airflow from Air Vents. This will be the first and most obvious sign your blower motor has a problem. …
- No Airflow At All From Vents. …
- Skyrocketing Energy Bills. …
- Strange Noises When You Turn on the Heat. …
- Overheating Blower / Weird Smells.
Can a bad blower motor resistor drain the battery?
The Blower Motor Resistor (properly referred to as the Final Stage Resistor, or FSR) will not lead to battery draining. It will cause the fan in the Ventilation System to not function properly — the fan speed selector will not work right, often causing only High Speed operation of the fan.
Why does my blower motor fuse keep blowing?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
Why is my blower fan not working?
If you see or hear the fan turn on, your blower motor is not the culprit. If the fan does not start, you have a wiring issue (circuit breaker trips) or motor problem (circuit breaker does not trip). While your thermostat may be at fault, only an HVAC technician can diagnose and remedy the issue correctly.
Can you fix 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).
Why does the fan in my car only work on high?
The blower motor resistor is prone to shorts, corrosion, and overheating. When the resistor fails, typically, the highest setting is the only option that still functions. This is because the air from the blower motor is bypassing the resistor, thus gaining the maximum amount of voltage, resulting in full power.
What is blower resistor?
The blower motor resistor is responsible for controlling the blower motor speed. In the past, this was done by varying the voltage supplied to the blower motor. In newer applications, the blower motor resistor is actually a solid state module that sends a varied signal to the blower motor.
