Swap out an overheated or corroded fan-speed resistor with the Dorman blower motor resistor 973-572, a front resistor and harness pigtail kit that directly replaces the original equipment on the 2008-2010 Dodge Grand Caravan, 2008-2010 Chrysler Town & Country and 2008 Chrysler Voyager.
The blower motor resistor helps control how fast the blower motor spins at each fan setting, so the HVAC system can move air at different speeds. Dorman pairs the resistor with a new harness pigtail so both can be replaced in one repair.
- Direct replacement: takes the place of the original equipment resistor and harness on the listed applications.
- Complete kit: each kit comes with a resistor and a harness pigtail, which most repairs require.
- Made to perform like original equipment: designed to help return full HVAC blower operation.
- Quality support: backed by Dorman's team of engineers and quality specialists in the USA.
A blower that runs on some speed settings but not others, or does not run at all, can be a sign the resistor may need replacing. Diagnose the circuit before replacing it, because a faulty blower motor, switch or wiring can cause similar symptoms. Engine details for each vehicle are listed in the "Vehicles it fits" section.

Frequently Asked Questions
What does a blower motor resistor do?
It helps control how fast the blower motor spins at each fan setting, so the HVAC system can move air through the cabin at different speeds.
What comes in the Dorman HVAC blower motor resistor kit?
Each kit includes a resistor and a harness pigtail. The pigtail is included because most repairs of an overheated or corroded original resistor need one.
Which vehicles does the Dorman blower motor resistor kit fit?
It is a direct replacement for the front resistor on vehicles such as the 2008-2010 Dodge Grand Caravan and 2008-2010 Chrysler Town & Country. See the "Vehicles it fits" section for details.
What are signs the blower motor resistor may need replacing?
A blower that works on some fan speeds but not others, or does not run at all, can be a sign of a failed resistor. Diagnose first, because a bad motor, switch or wiring can cause similar symptoms.
How is the 973-572 installed?
It replaces the original resistor and harness pigtail. Follow the vehicle service information for removing the old resistor and connecting the new pigtail.
