How Much Does A Heater Blower Motor Replacement Cost in the UK?

The heater blower motor in a vehicle is responsible for circulating air through the interior of the vehicle.

The air is then circulated through the vehicle's interior by the blower motor.

If the heater blower motor fails, it can be a very uncomfortable experience, cause uneven heating in the cabin and may make it especially difficult to see through the windscreen in colder temperatures.

Your heater blower motor is making strange noises

If you hear any slapping or sudden popping sounds or erratic whirring, it could likely be caused by damage to the blower fan.

Heater is not blowing air

When the air coming from the air vents is not as strong as it usually is and the fan's operating speed stays the same even when changing its speed.

Windshield does not clear up

In the event that your defroster is not clearing your windshield well, it may be a sign that the heater blower motor is defective. As a result, it can be difficult and unsafe to drive, so it's essential to have a qualified mechanic handle any necessary repairs as soon as possible.

Smoke smell from the vents

It is also possible for your vents to become filled with smoke or burnt-smelling if your heater's blower motor is damaged. It is best to keep your heating and air conditioning system off if this occurs and get it repaired as soon as possible.

Frequently asked questions about car heater blower motor replacement cost

Can you drive with a broken blower motor?

You can technically drive a vehicle with a broken blower motor but it’s best to get it repaired as soon as possible especially during the winter. A broken heater blower motor will prevent the heater (defroster) from working, which can be very dangerous in cold weather.

How do I know if I need to replace my blower motor or resistor?

The blower motor resistor is the component in the electrical system of a vehicle that regulates the amount of current flowing to the blower motor. The resistor is connected in line with the blower motor and is usually located near the blower motor or in the blower motor circuit. If the blower motor is only working at full speed, then the blower motor resistor may be the problem.

If the blower motor is not working, then a technician will first check the fuse. If the fuse is good, then the next step is to check the voltage at the blower motor. If there is no voltage, then the next step is to check the blower motor resistor.

Does a blower motor affect AC in a car?

A faulty blower motor can affect the air conditioning in a car by preventing the airflow from the vents.
