How to Buy a Good Quality Heater Blower Motor

The heater blower motor is part of the air conditioner and heater controls assembly, one of the many features created to make your ride as comfortable as possible. Your heater and air conditioner do the bulk of the work to assure that you’re riding in a controlled-temperature cabin, and there are a number of parts that support that process including the heater blower motor.

Your heater blower motor is controlled by the knob and/or buttons on your control console. When either the air conditioner or heater is turned on, the blower motor controls the amount of air that travels through the vents and the temperature. The blower doesn’t have a function if the heater or A/C is turned off. Even vehicles with no A/C system have a blower motor to run the fan and circulate the air within the cabin.

Here is some basic information to help assist choosing the right heater blower motor:

  • DC powered motors: The majority of heater blower motors are motors with a direct electrical current.

  • Brush strength: Be sure your heater blower motor has adequate brush strength.

  • Well oiled bearings: Bearings are equally important; keep them well-oiled or they may cause the motor to seize eventually.

  • Quiet operation: The new motor should be quiet and not vibrate, and should run normally at all speeds and in all modes.
