Dorman 973-442 HVAC Blower Motor Resistor Kit

Dorman 973-442 is an HVAC blower motor resistor kit for vehicles with climate control systems that need a replacement for an overheated or corroded original resistor. It includes the resistor and a harness pigtail to restore blower speed control on select Ford, Mercury, and Lincoln applications.

Key Features

• HVAC blower motor resistor kit with resistor and wire harness
• 6-inch wiring harness length for connector repair applications
• 5-wire, 5-terminal design with blade terminals
• Female connector with male terminals for direct replacement use
• 3 mounting holes for OE-style installation points
• Package contents include a blower motor resistor, wire harness, and butt connectors

Detailed Description

This Dorman blower motor resistor kit is built for climate control systems in applications such as the Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car. Part number 973-442 addresses common HVAC electrical failures caused by heat damage or corrosion at the resistor and connector, helping restore proper blower motor speed operation. This part cross-references 4P1587 and 6W7Z19E624A for the same application.

Compatible With 1992-2011 Ford Crown Victoria, climate control; 1991-2011 Mercury Grand Marquis, climate control; 1991-2005 Lincoln Town Car, climate control; 2003-2004 Mercury Marauder, climate control; 1991 Ford LTD Crown Victoria, climate control; and 1991 Mercury Colony Park, climate control. The Dorman 973-442 is a practical replacement when the original resistor connector shows signs of heat-related damage or terminal corrosion.

Common Repair Uses

• Restores blower motor speed control when fan settings stop working correctly
• Addresses intermittent HVAC blower operation caused by a damaged resistor circuit
• Replaces heat-damaged or corroded electrical connections at the resistor
• Helps correct loss of one or more blower speeds in climate control systems
• Supports repair of melted, loose, or oxidized blower resistor wiring

Installation Notes

Verify connector style, terminal count, and mounting-hole layout before installation. This kit uses blade terminals, a female connector, and a 5-wire harness; it does not include mounting hardware or a gasket/seal. Follow vehicle-specific service procedures when replacing the resistor and repairing the harness connection.

Quality Assurance

Dorman supplies OE-style replacement electrical components for HVAC repair applications. Part number 973-442 is engineered as a direct-fit service solution for select Ford, Mercury, and Lincoln climate control systems.
