What are the symptoms of a faulty blower motor resistor?
Another symptom of a faulty blower motor resistor is that the blower motor is not able to work on some settings. This causes the blower motor to malfunction or not function at all in one or more settings. It is highly probable that the blower motor switch has stopped working.
Can a blower motor relay be a problem?
One of the first symptoms of a problem with the blower motor relay is a blower motor that does not function at all. As the relay is the switch that supplies current to the blower motor, if it fails internally, then power will be cut off from the blower motor circuit, causing the motor to no longer function or blow any air from the vents.
How does a blower motor resistor control the fan speed?
The blower motor resistor controls the fan speed of the blower motor and the resulting change in air pressure produced by the movement of the blower fan. It accomplishes this by regulating the electric current that powers the motor.
What happens when a heater motor resistor fails?
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. 2. Blower motor does not work on certain settings
What happens if you lose the blower motor relay?
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. The blower motor relay controls the current used to power the blower motor,…
What are the symptoms of a bad blower motor resistor?
Another common symptom of a faulty blower motor resistor is a a blower motor that does not function on certain settings. If the blower motor resistors’ internal components fail it may cause the blower motor to malfunction, or not function at all on one or more of the settings.

What happens if you have a bad 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.
What are the different types of blowers and fans?
Major types are: centrifugal blower and positive-displacement blower. Centrifugal blowers look more like centrifugal pumps than fans. The impeller is typically gear-driven and rotates as fast as 15,000 rpm.
What are the symptoms of a failed blower motor resistor?
Blower motor resistor problems. 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 high speed and doesn’t work at low speeds.
Which is the working principle of a blower?
Working Principle Of A Blower Each blower works differently according to the motor power. 1-Inlet 2-Side Channel 3-Fan 4-Outlet Blowers increase the pressure of the absorbed gas by a series of vortex motions formed by the centrifugal movement of the impeller.

What should be included in a new blower assembly?
This will allow the operating efficiency of the system to increase to a level that will delight your customer and make them loyal to you forever. Most of the time an Electronically Commutated Motor (ECM), will be included with your new blower assembly and will be your best choice.
