Blower Motor Resistor Replacement

How are blower motor resistor issues diagnosed?

The mechanic will perform a series of tests that can lead to the blower motor resistor. This includes checking fuses and making sure the resistor is receiving power. If power reaches the blower motor resistor, but the blower motor does not receive that power, the resistor is probably faulty. It will be removed, inspected and bench tested to make sure it's the culprit.

How is a blower motor resistor replaced?

Either the glove box or lower cover will be removed from the dashboard to grant access to the blower motor service cover. The cover is removed, and the blower motor resistor is disconnected from its electronic connectors. Finally, the blower motor retaining screws will be removed, and the blower motor will be taken out. The new resistor will be installed into the blower motor, and then the unit will be put back in the reverse of the order listed above.

Testing is imperative to making a proper diagnosis. We recommend disconnecting the battery any time there is an open electrical circuit.

Can I replace the heater blower motor resistor myself?

A skilled DIYer can accomplish this diagnosis and repair. A basic understanding of a series electrical circuit, a few basic tools, and a digital voltage meter are all that is required. It's important that the DIYer understand the testing procedures for the blower motor circuit, as failing to properly test the blower motor may lead to unnecessary costs. If you feel uncertain about this repair, take it to a certified mechanic instead.
