Deal with an overheated or corroded blower resistor and its wiring connection in one job with the Dorman blower motor resistor and harness kit, part number 973-441, a direct replacement for the 1984-1996 Jeep Cherokee, 1986-1992 Jeep Comanche and 1984-1990 Jeep Wagoneer.
The blower motor resistor sets the fan speeds of the HVAC system by routing the blower's current through different levels of resistance. This Dorman hvac blower motor resistor kit pairs a new resistor with a harness pigtail, so the connection can be replaced along with the resistor.
- Direct replacement: designed to directly replace the original equipment resistor and harness on the listed Jeep applications.
- Resistor and pigtail included: each kit contains a resistor plus a harness pigtail, a piece Dorman calls essential for most repairs.
- OE-like performance: made to perform like original equipment, intended to return full HVAC operation when a failed resistor is the cause.
- Engineering support: backed by Dorman's team of engineers and quality specialists in the USA.
Signs a blower motor resistor may need replacing include a fan that runs on some speed settings but not others, a blower that works only on the highest setting, or no blower operation at all. Switches, wiring and the blower motor itself can produce similar symptoms, so diagnose the cause before replacing parts. See the "Vehicles it fits" section for engine-specific details.

Frequently Asked Questions
What does a blower motor resistor do?
It sets the blower fan's speeds by routing current through different levels of resistance, so each switch setting gives a different fan speed.
What comes in the Dorman blower motor resistor kit?
Part number 973-441 includes a blower motor resistor and a harness pigtail, so the wiring connection can be replaced along with the resistor.
Which Jeep models does 973-441 fit?
It is a direct replacement for the 1984-1996 Jeep Cherokee, 1986-1992 Jeep Comanche and 1984-1990 Jeep Wagoneer. Check the "Vehicles it fits" section for engine details.
What are signs of a failing blower motor resistor?
Common signs include a fan that works on some speeds but not others, runs only on high, or won't run at all. Other HVAC faults can cause similar symptoms, so diagnose first.
Why is a harness pigtail included?
Dorman includes the pigtail because it is essential for most repairs. Follow the vehicle's service information for the installation steps.
