Honda Fit blower motor fast high 2009 2010 2011 2012

May 17, 2023

American Honda reports that some 2009-12 Fit models may come into your store with a customer complaint that the blower motor only operates on high speed. One likely cause of the trouble, the car maker said, is a blown blower resistor. The resistor fails due to excess current draw from the motor itself.

Replacing the blower motor and resistor with updated parts (part No. 79310-TF0-G01 and part No. 79335-TF0-G01, respectively) should eliminate the condition.

Begin the fix by removing the dash undercover from the passenger side of the vehicle. Following the illustration, disconnect the blower motor connector, remove the three retaining screws and remove the motor from the vehicle. Install the new motor using the same screws, then reconnect the electrical connector.

Now move on to the blower resistor. It will be to the left and slightly behind the blower motor, as shown. Disconnect its electrical connector, then remove the two retaining screws, followed by the resistor itself. Install the new resistor using the same two screws, then reattach the connector. To complete the fix, install the dash undercover, then check that the blower motor operates properly.
