The user chooses a suitable fan speed by using a selector to connect one of the resistors in the blower resistor pack. The primary purpose of a blower motor resistor is to moderate the revolutions of your blower motor.

This illustration shows a typical blower resistor specifications and test.

What is the purpose of a blower motor resistor block. In some cars a failed blower motor resistor can cause a heater fan to. This means that the current running through the blower motor and thus is speed is controlled by the resistor value. It is responsible for controlling the blower motors fan speed.

Ac blower motor resister. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. Getting a new the blower motor resistor can help better the cooling operation.

If the blower motor resistor continuity does not check ok replace the faulty resistoryou need a multimeter to test the resistor block and there should be continuity between all terminals. These resistors allow the blower motor to function at lower speeds. A quality blower motor resistor is indispensable for summer driving comfort.

The cars blower motor resistor is a critical component of your heating and cooling unit. Blower motor resistor control module problems. If the blower motor resistor continuity does not check ok replace the faulty resistoryou need a multimeter to test the resistor block and there should be continuity between all terminals.

The blower motor resistor is an electrical component that is a part of the vehicles heating and air conditioning system. 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. A blower resistor uses resistance to control the speed of the blower motor.

If the resistor shorts or fails it may cause the blower motor to remain stuck on one fan speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. Problems with a blower motor resistor are common in many cars.

The most common symptom of a failed blower motor resistor is when the heater fan only runs at the highest speed setting 4 or 5 and doesnt work at low speeds. In high speed the resistor is bypassed and power is fed to the motor directly from the switch. A blower motors speed is adjusted with a blower motor resister.

The blower resistor is connected in series with the blower fan.
