Honda Blower Motor

Choosing A Cabin Blower Motor

A cabin blower motor drives the fan that moves air through the heating and air-conditioning housing. Choose the front or rear position required by the vehicle and compare the connector, mounting flange and fan-wheel arrangement. Vehicles with separate rear climate equipment may use a different blower for that unit.

Some A-Premium blower assemblies include the fan wheel; selected packages also include a speed-control resistor. Check the parts listed for the specific package before planning the repair.

How An HVAC Blower Moves Air

The blower pushes cabin air through the HVAC housing for ventilation, heating or cooling. The same fan can move air in each of those modes; the heater core, refrigerant circuit and air doors perform different functions.

A motor that runs but moves little air may need a different check from a fan that does not turn. Inspect the airflow path as well as the electrical supply and speed-control circuit when symptoms point to either.

Blower Motor Wheels And Mounting

The fan wheel and its housing must have the correct clearance and mounting arrangement. An assembly supplied with its wheel avoids transferring that particular piece, but still needs the correct electrical connection and fit for the HVAC housing.

Keep hands clear of the fan whenever it might be powered, and use the vehicle's service procedure before opening the housing.
