Dorman HVAC Blower Motor Resistor Kit 973-426 — Direct-Fit with Harness Pigtail, Restores Fan Speeds

The Dorman 973-426 HVAC Blower Motor Resistor Kit is a direct-fit replacement resistor and harness pigtail designed to restore your vehicle's HVAC fan speed control when the original resistor has overheated or corroded.

When a dash fan works only on certain speeds or stops responding, the blower motor resistor is a common culprit. This Dorman kit pairs a precision-matched resistor with a compatible harness pigtail so you can replace the worn or damaged OE component quickly and reliably. Manufactured with engineering oversight in the USA, the kit is built to match the fit and function of original equipment on select years, makes and models.

How will this kit restore my HVAC blower performance?

Replacing a failed resistor restores the electrical pathway that controls blower motor speeds so all fan settings operate again. The included harness pigtail ensures proper connections and eliminates the need to reuse a brittle or melted factory plug.

• Re-establishes full speed control across all fan settings
• Prevents intermittent fan operation and sudden failures
• Includes harness pigtail to ensure secure, corrosion-resistant connection

Is the Dorman 973-426 an exact fit for my vehicle?

This kit is manufactured as a direct replacement for specific vehicle applications to match original mounting, electrical terminals, and airflow clearances. Always verify fit by entering your vehicle make, model and trim in the seller’s garage tool or parts catalog before ordering.

• Direct OE-style design for correct fit and function
• Engineered to match OEM terminal layout and mounting points
• Compatibility confirmation available through vehicle lookup tools

What does the kit include and how easy is installation?

The kit contains the blower motor resistor and a harness pigtail so you can replace both the component and the often-damaged connector in one service. Basic hand tools and a short amount of time are typically all that's required; many installations are accessible from under the dash or behind the glovebox depending on the vehicle.

• One blower motor resistor built to perform like the original
• One harness pigtail to replace corroded or melted OE wiring
• Simple bolt-and-plug installation—no complex wiring modifications

How does Dorman ensure quality and reliability?

Dorman designs replacement parts with input from engineers and quality specialists to provide consistent, long-lasting performance. Their parts are produced and inspected to meet the fit, form and function expectations of aftermarket repairs.

• Engineered oversight and quality control in U.S.-based teams
• Manufactured to replicate OE performance characteristics
• Supplies replacement components for common automotive service needs

Who is this for: The Dorman 973-426 kit is suited for DIY mechanics, professional technicians, and fleet maintenance teams who need a dependable, direct-replacement blower motor resistor and harness for compatible vehicle applications. If your HVAC fan skips speeds, runs only on high, or the resistor plug shows heat damage or corrosion, this kit provides the parts needed to complete a straightforward, effective repair.
