The Dorman 973-426 kit includes a resistor and a harness pigtail engineered to match original equipment fit and function for specific years, makes and models. Designed and tested by Dorman engineers, this kit is meant to make the repair straightforward and to bring your heating and cooling system back to normal operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Dorman 973-426 kit fix blower fan speed problems?\u003c\/h3\u003e\n\u003cp\u003eThis kit replaces the resistor assembly that controls blower motor speeds, along with the electrical pigtail that commonly fails from heat or corrosion. Installing the kit reestablishes the electrical path the HVAC control uses to step through speeds, allowing the fan to respond correctly to the selector. The result is restored multi-speed control and reliable airflow from the HVAC system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes both resistor and harness pigtail for a complete repair.\u003c\/li\u003e\n  \u003cli\u003eReplaces overheated, corroded or damaged OEM components.\u003c\/li\u003e\n  \u003cli\u003eRestores low-to-high speed function of the blower motor.\u003c\/li\u003e\n  \u003cli\u003eEngineered to fit vehicle-specific locations and connectors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat vehicles and situations is this part compatible with?\u003c\/h3\u003e\n\u003cp\u003eDorman publishes application details for each part number; compatibility depends on vehicle year, make, model and trim. Use the vehicle lookup tool or consult fitment charts to confirm the 973-426 matches your car. This kit is intended for vehicles where the original resistor and pigtail design matches Dorman's replacement pattern.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits select vehicles—verify with vehicle lookup before ordering.\u003c\/li\u003e\n  \u003cli\u003eSuitable when original resistor shows heat damage, melting or corrosion.\u003c\/li\u003e\n  \u003cli\u003eWorks when blower motor runs only on one speed or not at all.\u003c\/li\u003e\n  \u003cli\u003eCommon repair for older connectors that suffer electrical failure over time.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow difficult is the installation, and what should I expect?\u003c\/h3\u003e\n\u003cp\u003eInstallation is typically a straightforward, vehicle-level repair that can be completed with basic hand tools. The blower resistor is usually accessible from under the dash or behind the glove box; the harness pigtail connects to the resistor and the vehicle wiring. If you can follow simple automotive procedures and disconnect a battery, you can often complete the swap yourself or have it installed quickly by a technician.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBasic tools and a safe, level workspace are usually sufficient.\u003c\/li\u003e\n  \u003cli\u003eDisconnect battery power before handling HVAC electrical components.\u003c\/li\u003e\n  \u003cli\u003eReplacement often requires removing a small trim panel or glove box for access.\u003c\/li\u003e\n  \u003cli\u003eFollow vehicle service instructions or consult a technician if unsure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat quality assurances come with this Dorman replacement?\u003c\/h3\u003e\n\u003cp\u003eDorman designs and inspects replacement parts with input from engineers and quality specialists to provide reliable aftermarket alternatives. The 973-426 is built to match original form and function, offering a practical solution when the OE resistor or connector fails. While aftermarket parts vary, Dorman emphasizes fitment accuracy and component durability in this kit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eManufactured with quality controls overseen by Dorman engineering teams.\u003c\/li\u003e\n  \u003cli\u003eBuilt to perform like the original equipment part in compatible vehicles.\u003c\/li\u003e\n  \u003cli\u003eSold as a complete kit to reduce installation guesswork and additional purchases.\u003c\/li\u003e\n  \u003cli\u003eRecommended to verify fit using vehicle make, model and trim lookup tools.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Dorman 973-426 HVAC Blower Motor Resistor Kit is for vehicle owners, DIY mechanics and repair shops needing a reliable, direct-style replacement for a failing blower motor resistor and its harness pigtail. If your HVAC fan exhibits limited speed options, intermittent operation, or the resistor shows visible heat or connector damage, this kit provides a practical repair option designed to restore normal airflow control when matched to the correct vehicle application.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this kit restore all blower fan speeds?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, when the resistor and pigtail are the cause, installing this kit restores full multi-speed control.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special tools to install it?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No special tools are usually required—basic hand tools and battery disconnection are typically sufficient.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Dorman","offers":[{"title":"Default Title","offer_id":48084414562462,"sku":"B00FOOV40W","price":32.15,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/dorman-973-426-front-view.jpg?v=1785854571","url":"https:\/\/northtrailauto.ca\/products\/dorman-hvac-blower-motor-resistor-kit-973-426-with-harness-pigtail-restores-multi-speed-fan-control","provider":"North Trail Auto","version":"1.0","type":"link"}
