Dorman Blower Motor Resistor Kit 973-582 — Direct-Fit Resistor & Harness Pigtail Restores Blower Speed Control

If your vehicle's blower fan is stuck on one speed, not working at all, or the resistor shows signs of overheating or corrosion, this kit gives you the two parts technicians most often replace: the resistor assembly and the harness pigtail. Manufactured to match original equipment function, the Dorman kit aims to make repairs straightforward while avoiding the expense of replacing the entire blower motor assembly.

How does this kit restore my HVAC blower's performance?

The resistor controls the fan speeds by regulating electrical current to the blower motor. When the resistor or its connector fails, fan speeds can become limited or inconsistent. Replacing both the resistor and the harness pigtail removes common failure points and re-establishes reliable speed control.

• Includes replacement resistor and matching harness pigtail for secure connections.
• Engineered to deliver the same resistance values and electrical path as the original part.
• Eliminates intermittent fan speeds caused by corroded terminals or melted housings.

Which vehicles and situations is the Dorman 973-582 kit compatible with?

This part is designed to be a direct replacement on select model years, makes, and trims—check fitment before purchase. It is intended for vehicles where the original resistor or connector has failed due to heat, corrosion, or physical damage.

• Direct-replacement fit for specific vehicle applications—verify with the vehicle lookup tool.
• Commonly used when the factory resistor overheats or the harness pigtail is brittle or melted.
• Avoids unnecessary blower motor replacement when only the resistor or connector is faulty.

What are the key features and build quality of this Dorman resistor kit?

Dorman emphasizes functional equivalence to OE parts and backs their components with engineering oversight. The kit is supplied with connector hardware and a resistor element built to match original resistance values, improving longevity when properly installed.

• Direct replacement design to match the original equipment geometry and electrical characteristics.
• Complete kit packaging includes the resistor and harness pigtail for a full repair.
• Produced under quality control standards supported by Dorman engineers and specialists in the USA.

How difficult is installation, and what should I prepare for?

Installation is typically a moderate DIY job or a quick shop repair: access to the blower housing and basic hand tools are usually all that’s required. Disconnect the battery, remove the blower housing cover, unplug the old resistor, and install the new components following vehicle-specific steps.

• Preparation: vehicle-specific service manual or online guide recommended.
• Tools: basic hand tools, possibly a flashlight and trim removal tools depending on access.
• Time: many installations take under an hour for experienced DIYers, longer if dashboard components must be removed.

Who is this for? The Dorman 973-582 HVAC Blower Motor Resistor Kit is aimed at DIY mechanics, independent repair shops, and vehicle owners looking to repair blower speed issues without replacing the entire motor. If your blower operation is inconsistent or you see damage or melting at the resistor or connector, this kit offers the essential parts to complete a targeted, cost-effective repair. Always confirm vehicle fitment using your make, model, year, and trim before ordering to ensure compatibility.
