Product Details

The Dorman 645-509 Blower Motor Resistor Harness is designed to replace worn, corroded, or damaged blower motor resistor connectors in your vehicle's HVAC system. This 4-wire pigtail harness provides a direct repair solution without requiring replacement of the entire wiring system.

Key Features:

  • 4-wire design for proper blower motor speed control
  • Durable construction resists heat and corrosion from HVAC operation
  • Direct plug-in connection to blower motor resistor
  • Restores reliable operation of heating and air conditioning fan speeds
  • Quality-tested connector terminals for secure electrical contact
  • Cost-effective alternative to dealership parts

Blower motor resistor connectors are subjected to high heat and electrical load, making them prone to melting, corrosion, and connection failure over time. This replacement harness eliminates intermittent blower operation, fixes non-working fan speeds, and restores full climate control functionality. The pigtail design allows you to splice into existing wiring for a permanent repair.
