What causes a blower motor resistor to burn out?

In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.

Can a blower motor be repaired?

Blower Motor Replacement: When Good Parts Go Bad. … There are a number of things that can go wrong with your heating system, but if the air stops blowing altogether and the same is true on cold air settings, a blower motor replacement is likely in order. The good news is that it’s a fairly straight forward repair.

How often do blower motors go out?

Even though the manufacturer states their blower motor will last two decades, we advise all clients to expect a 10-20-year life span due to age, use, and proactive maintenance.

Can I bypass blower resistor?

Bypassing the resistors should run the fan on high speed. High speed requires more DC current, so high speed was fed through a relay and heavier wire to prevent the wire from burning up.

Is there a fuse for the blower motor?

The blower motor is powered by a fuse-like device called a relay. If your heater or air conditioner does not blow air through the vents, this could indicate that the blower motor fuse has probably blown. While replacement is easy, the exact location of your blower motor fuse may vary from vehicle to vehicle.

Where is the resistor located in blower motor?

On many vehicles, the blower motor resistor, which comes as a module that connects to an electrical wire and is mounted near the blower motor, is accessible by removing the glove box or checking under the dashboard. On others it’s behind the dashboard, and part of the dashboard may have to be disassembled to reach it.

Will a blower motor work without the resistor?

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.

Why is my blower motor not working?

In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. … Start by checking the blower fuse and HVAC controller fuse.

What happens if the blower motor goes out?

No air from the vents

If the heater blower motor burns out or short circuits, it will not function, and therefore will not be able to produce any airflow for the system. The blower motor will usually have to be replaced in order to restore proper operation to the system.
