Common questions about replacing the blower motor

How do I tell if the blower motor is faulty?

The signs of a malfunctioning blower motor are humming and rattling sounds when it’s operating as well as reduced heating efficiency. The fan may fail to turn on. In this case, use a multimeter to check whether the voltage is supplied to the motor. If there are no problems in the electrical circuit, then it’s the motor that’s faulty.

What can cause blower motor breakdown?

One of the main reasons is wear of the motor brushes. In some cases, these can be replaced. Sometimes, due to being exposed to moisture and dirt, the internal terminals of the mechanism get corroded. Due to voltage surges in the car electrical system, the armature winding can burn out. In the last two cases, you will have to install a new motor.

Can I replace the blower motor myself?

Yes, you can, but bear in mind that the replacement procedure varies significantly depending on the vehicle make and model. For example, on some cars you need to disassemble the dashboard and remove the pedal assembly. On others, the wiper arms should be removed. For detailed instructions on replacing the blower motor on your exact vehicle, see your car’s service manual.
