Give your front blower's speed control a fresh start with the Dorman HVAC blower motor resistor kit, part number 973-422, which pairs a new resistor with a harness pigtail to replace an overheated or corroded original equipment resistor. It fits many vehicles, among them the 2001-2007 Dodge Grand Caravan, 2001-2007 Chrysler Town & Country and 2005-2008 Chrysler Pacifica. See the "Vehicles it fits" section for the full list and engine details.
The blower motor resistor sets the front blower's speeds by controlling the current that reaches the blower motor. When the original resistor overheats or corrodes, the fan may run on only some settings or stop working altogether. If a failed resistor is the cause, this kit replaces it and supplies a fresh harness pigtail at the same time.
- Direct replacement: designed to directly replace the original equipment resistor and harness on the listed applications.
- Resistor plus pigtail: every kit includes a resistor and a harness pigtail, which is essential for most repairs.
- OE-like performance: made to perform like the original equipment and intended to return the HVAC blower to full operation.
- Engineered support: backed by a team of engineers and quality specialists in the USA.
This Dorman blower motor resistor is sold as a kit for the front HVAC blower. Follow the vehicle service information when installing the resistor and connecting the new pigtail.

Frequently Asked Questions
What does a blower motor resistor kit do?
The resistor controls the current reaching the front blower motor so the fan can run at different speeds. This kit pairs the resistor with a harness pigtail.
What comes in the box?
Each kit includes a resistor and a harness pigtail. The pigtail is essential for most repairs.
What are signs the blower motor resistor may need replacing?
Signs include a fan that works only on high, speed settings that no longer respond, or a blower that stops working. Other faults can cause these, so diagnose the circuit before replacing parts.
Does it fit a 2001-2007 Dodge Grand Caravan?
Yes, it is a direct-fit replacement for the 2001-2007 Dodge Grand Caravan and the 2001-2007 Chrysler Town & Country. Check the "Vehicles it fits" section for your exact vehicle.
How is this kit installed?
Install the resistor and connect the new harness pigtail according to the vehicle's service information. The kit is designed to directly replace the original equipment resistor.
