Where is the blower motor resistor?

It’s located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.

How do I know if my blower resistor is bad?

Symptoms of a Bad or Failing Heater Blower Motor Resistor

Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting.
Blower motor does not work on certain settings.
No air from the vehicle’s vents.

How do I remove the blower motor resistor?

How to Replace a Blower Motor Resistor

Remove the negative battery terminal.
Locate the blower motor resistor on the passenger side under the dash board.
Disconnect the electrical connector to the blower motor resistor.
Remove the screws or bolts to the blower motor resistor and remove the resistor.

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

about 45 minutes

How long does a blower motor last?

between 12 and 15 years

How do I clean the blower motor in my car?

Here’s what to do:

Disconnect car battery.
Detach the blower motor from its connector.
Unscrew all the screws on the blower motor.
Locate the retainer clip in the center of the blower wheel.
Clean out any debris from the motor.
Clean the blower motor with an electrical-parts cleaner.
Oil the bearings.

Do I need a blower motor or a resistor?

Typically, if the fan will work on some speeds but not on others, the resistor is suspect. If the fan won’t work on any speeds except high speed, the blower resistor’s thermal fuse may have failed, meaning the entire resistor needs to be replaced.

Why is the blower motor in my car making noise?

Loud noises you hear when your car’s heater or air conditioner are on typically indicate a blower motor issue. The good news is that a blower motor problem like this can be the result of something as simple to fix as debris or trash that got caught in it.

Can you fix a blower motor resistor?

The resistor module is easy and inexpensive to replace. It’s then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25).

What does a resistor do for a blower motor?

Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever, or electronically by the air conditioning system.

Why are my car vents not blowing air?

Here are some of the most common causes of why air doesn’t flow out of your vehicle’s vents: 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.

How do I fix my car AC not blowing air?

Part 1 of 3: Checking the inside of the car

Step 1: Turn on the AC.
Step 2: Verify that air is blowing.
Step 3: Check the strength of airflow.
Step 4: Check the temperature of air.
Step 1: Check for any airflow obstruction.
Step 2: Check the AC belt.
Step 3: Listen and inspect the compressor.
Step 4: Check the fuses.

What controls the vents in a car?

The vents for modern vehicles are controlled by three or four electrical actuator motors, which can be adjusted by the climate control module; this electronically regulates and control the air ventilation system in your vehicle.

How do I increase the airflow in my vents?

5 Ways to Improve Airflow in Your Home

Check Vents and Registers. One of the simplest things you can do to increase airflow in your home is to check the vents and registers in each room.
Turn on Ceiling Fans.
Schedule HVAC Maintenance.
Consider Duct Cleaning.
Invest in a Ventilator.

Why isn’t my air or heat working in my car?

A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn’t allowing the engine to properly warm up. A blower fan that isn’t working properly.
