Replace an overheated or corroded original resistor with the Dorman HVAC blower motor resistor kit, part number 973-543, which pairs a new resistor with a harness pigtail. It fits many vehicles, among them the 2005-2019 Nissan Frontier, 2005-2012 Nissan Pathfinder and 2005-2015 Nissan Xterra. See the "Vehicles it fits" section for the full list and engine details.
The blower motor resistor regulates the current sent to the HVAC blower motor so the fan can run at its different speed settings. The catalog lists this kit for front and rear positions. Dorman designed this resistor to directly replace the original equipment resistor on the listed applications.
- Direct replacement: The resistor and harness kit is built to take the place of the original equipment on the listed applications.
- Resistor plus pigtail: Each kit includes both a resistor and a harness pigtail, which Dorman notes is essential for most repairs.
- Original-equipment performance: Made to perform like the original equipment, so it is intended to bring back full HVAC operation when the resistor is the cause of the problem.
- Engineering support: Backed by Dorman's USA-based team of engineers and quality specialists.
Signs this part may need replacing: the blower runs only on high, one or more fan speeds stop working, or there is no airflow at some settings. Diagnose the cause before replacing the part, since a faulty switch, wiring fault or blower motor can cause similar symptoms.

Frequently Asked Questions
What does a blower motor resistor do?
It regulates the current reaching the HVAC blower motor so the fan can run at different speeds. When the resistor fails, one or more fan speeds may stop working.
What comes in the Dorman blower motor resistor kit?
Each 973-543 kit includes a resistor and a harness pigtail. Dorman notes the pigtail is essential for most repairs.
What are signs the blower motor resistor may need replacing?
Common signs include a blower that runs only on high, missing fan speeds, or no airflow at some settings. Check the switch, wiring and motor first, since they can cause similar symptoms.
Will this fit my 2005-2019 Nissan Frontier?
Yes. The 2005-2019 Nissan Frontier is a listed application, along with the 2005-2012 Nissan Pathfinder and 2005-2015 Nissan Xterra. The "Vehicles it fits" section shows the full list.
How is the 973-543 installed?
It installs as a direct replacement for the original equipment. Follow the vehicle service information to replace the old resistor and connector with the included resistor and harness pigtail.
