How To Test And Replace Your Blower Motor Resistor Youtube If it’s good, check for debris on the evaporator or heater. decreased airflow causes the blower motor resistor to overheat and fail. reduced airflow also causes the blower motor to work harder, draw more current and that can cause repeat blower motor resistor failures. the blower motor fuse blows repeatedly. the blower motor is drawing too. Here are some tips on how to test your blower motor resistor: start by looking for the blower fan resistor. a repair manual can tell you where its location is in your vehicle’s make and model. inspect the resistor visually. look for obvious signs of corrosion and burns from overheating.

The blower motor resistor is responsible for controlling the speed of the blower motor in your car’s hvac system. it works by regulating the amount of electrical current that flows through the fan motor. the resistor does this by varying the resistance of the coil. the higher the resistance, the less current flows through the motor, which. How to test your blower motor and resistor without taking your dashboard apart.time stamps (click the time to go to that part of the video)0:00 how to test b. Testing the voltage at the blower motor. if there is a voltage at the motor (at least 4 6 volt at low speed and 12 volt at high speed), but the motor doesn't run, the motor is bad. things like leaves, twigs, nuts, pieces of a ripped cabin filter can jam the blade of the blower motor. this happens often in many cars.

In this video i go through my process of finding a bad blower motor resistor, through testing each component related to blower motor operation. hope you enjo. Symptoms of a bad blower motor resistor. when the blower motor resistor goes bad, the motor can get stuck at one speed. the various airflow settings may also fail to work or you may not get any air from the vents. furthermore, it can cause an inconsistent or intermittent fan speed, leaving you without proper airflow. dive into these symptoms.
