Where is the blower motor resistor located at?

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.

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.

How much should it cost to replace a blower motor?

Replacing a blower motor costs $450 on average with a typical range of $250 to $800. With a warranty, you might pay as little as $150 for labor alone. For high-end models, like those with large motors or access issues, you might pay as much as $2,000.

What happens when blower motor resistor goes bad?

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.

What are the signs of a bad blower motor?

What happens when blower motor relay goes bad?

If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.

How long does it take to replace a blower motor resistor?

takes about 45 minutes.

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.

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.

Why is my car not blowing out any air?

Your air intake is clogged, meaning that air isn’t getting in from the outside at all or isn’t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay. Damaged blower motor.
