What is the function of a blower motor resistor?
A blower motor resistor is an adjustable resistor. This electric component is used to regulate a vehicle’s air conditioning system, it is the part that controls the blower motor’s fan speed according to the settings which can be changed by using the knob and turning it left or right which would increase…
Where is the blower motor resistor on a Mazda 5?
In many cars it’s fairly easy; the blower motor is located behind the glove box and held by 3-4 screws. In others it might be located inside the dash (e;g Mazda 5) which makes replacement difficult. If you need a proper diagnostic procedure, we posted several links where you can access a service manual for your car for a subscription fee.
Where is the blower motor resistor located on a Ford Escape?
In the 2008-2011 Ford Escape, the resistor is located behind the glove box on top of the HVAC unit air duct. It’s held by two screws and is easy to replace. See the photo. In the 2008-2011 Ford F150 the blower motor resistor is also located behind the glove box, but is installed in the right side of the plastic air duct.
Can a faulty blower resistor cause no air to flow?
Since the blower resistor is directly responsible to transfer the power from battery to the blower itself, a symptom of the faulty blower motor resistor is that no air flows from the car’s vent.
Could You Tell Me the location of the blower motor resistor?
Find the blower resistor and detach it from the rest of the circuit. For the precise location, consult the repair manual for your car’s make and model. Some common locations are near the blower fan motor, under or behind the dashboard, around the passenger footwell etc.
Where is the blower motor located?
Heater Blower Motor Resistor Symptoms, Function & Location. The motor that spins that fan is called a blower motor. It is located inside the dashboard usually on the opposite side of the steering wheel or the inside of the engine compartment on the firewall. In almost every modern car out there, the blower speed can be adjusted.
Where is the AC blower location?
The blower fan is located inside a horizontal air conditioning unit in many home air conditioning systems, especially when the air handler is located in an attic or crawl area. The location of a blower fan in vertical “up flow” or “down flow” heating and cooling systems is illustrated in additional sketches and photographs below.
Where is blower motor?
Most passenger cars and trucks have heater boxes and blower motors that are located inside the passenger compartment , but there are some instances where the heater box, blower motor, or both, are located in, and accessed from, the engine compartment.
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.
What are the symptoms of a bad heater motor resistor?
Symptoms of a Bad or Failing Heater Blower Motor Resistor. 1 1. 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. The blower 2 2. Blower motor does not work on certain settings. 3 3. No air from the vehicle’s vents.
What does the resistor on a heater do?
It is responsible for controlling the blower motor’s fan speed. When fan speed is changed via the knob on the instrument cluster, the blower motor resistor changes setting, which changes the speed of the blower motor.
Where is the resistor for the blower motor located?
Two individual resistors make up the blower motor resistor assembly on your Chevy pickup. As you’re probably already aware, these resistors are located between the A/C-Heater control panel and the blower motor . The purpose of these resistors is to reduce the amount of the blower motor’s current that’s passing through them.
What is a HVAC blower?
An air blower, also called a centrifugal fan or squirrel cage fan, is used commonly for exhaust or in heating, ventilation, and air-conditioning (HVAC) systems. The HVAC blower motor turns a rotor within the housing, producing centrifugal force that creates high pressure for moving large amounts of air to ducts and vents.
Where is the blower motor resister?
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.
What is a car heater blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
