Dorman - OE Solutions HVAC Blower Motor Resistor Kit P/N:973-504
Take charge of cabin airflow at every fan setting with the Dorman blower motor resistor 973-552, a kit that pairs a new resistor with a harness pigtail. It is a direct replacement for the original equipment on the 2008-2010 and 2012-2015 Mazda 5.
A blower motor resistor controls the voltage sent to the blower motor, which gives the HVAC system its lower fan speeds. This Dorman blower motor resistor kit is intended to replace an original resistor that has overheated or corroded, and the included pigtail replaces the connector along with it.
Signs this part may need replacing: the fan runs only on high, one or more speed settings stop working, or the resistor connector shows heat damage or corrosion. See the "Vehicles it fits" section for engine-specific details.

This part cross-references / interchanges with the following part numbers:
What does a blower motor resistor do?
It changes the voltage fed to the blower motor so the HVAC fan can run at its lower speed settings. When it fails, some or all fan speeds may stop working.
What comes in the Dorman hvac blower motor resistor kit?
Each 973-552 kit includes a blower motor resistor and a harness pigtail, so the connector can be replaced along with the resistor if it has overheated or corroded.
What are signs the blower motor resistor may need replacing?
Common signs include a fan that runs only on high, missing speed settings, or a scorched or corroded resistor connector. Diagnose the cause first, since a switch, motor or wiring fault can cause similar symptoms.
Will this fit my 2012-2015 Mazda 5?
Yes. The 973-552 is listed as a direct replacement for the 2012-2015 Mazda 5, and it also fits the 2008-2010 Mazda 5. The "Vehicles it fits" section has the details.
How is this resistor kit installed?
It installs in place of the original resistor, and the harness pigtail replaces the old connector. Follow the vehicle service information for the wiring connection, and disconnect the battery before starting.
