Heater Blower Motor Replacement

What is a heater blower motor?

Through a unique “squirrel cage” design, a blower motor draws air into a vehicle’s climate control system, and forces it into the various vents. This air will pass through either the heater or evaporator core to treat the needs of the passenger or the car. The blower motor runs on a high amount of amperage that is controlled by a switch in the climate control center and a blower motor resistor.

What are the symptoms of a faulty heater blower motor?

If no air comes out of the vents when the climate control is commanded on, then the blower motor has likely burned out. Water intrusion into the air inlet, high moisture in the air or a clogged cabin air filter will make the blower motor work harder, draw higher amperage and ultimately overheat. The big problem here is the amperage draw may also overheat and burn the resistor and the control unit.

How severe is a faulty heater blower motor?

Not a problem that will leave you stranded on the side of the road, but in the lows of winter or the highs of summer, a non-working blower motor may make traveling quite uncomfortable. If you do not look forward to sweating or shivering then find a good mechanic. The replacement of the blower motor is common and effortless, so most shops will perform the repair; many on the same day.

What is the typical cost to replace a heater blower motor?

  • Estimated part(s) cost = $50 - $100
  • Estimated labor cost= $80 - $100
  • Estimated total cost = $130 - $200

In most instances this repair is on the relatively inexpensive side. A new blower motor will run between $50 and $100. Most blower motors sit in the dash underneath the glove box, and are accessible for replacement. Installation will run in the range of $80 to $100. If the heater motor needs to be changed at the same time, the price for a new one will run around $40-$50.

Keep in mind, pricing will vary by location and your vehicle make and model. If you're not already, save time and money by using Openbay to compare pricing and book an appointment with a service center in your area.
