Dorman 973-534 HVAC Blower Motor Resistor Kit

Dorman 973-534 HVAC Blower Motor Resistor Kit

Dorman 973-534 is an HVAC blower motor resistor kit for select Ford Taurus and Mercury Sable applications. It includes the resistor and a replacement harness pigtail to address common blower speed control failures caused by heat damage or corrosion at the original connector.

Key Features

• HVAC blower motor resistor kit with resistor and wire harness
• Direct replacement for overheated or corroded original equipment resistor assemblies
• 4-blade terminal design with 4-wire harness configuration
• Female connector with male terminals for proper electrical connection
• 6-inch wiring harness length
• Mounting hole count: 4
• Package contents: blower motor resistor and wire harness

Detailed Description

This Dorman HVAC blower motor resistor kit is built for vehicles that have lost one or more blower speeds due to resistor or connector damage. The resistor manages blower motor speed by controlling electrical current, while the included harness pigtail replaces a heat-affected connector that can cause intermittent operation, melted terminals, or complete blower failure. It is a practical replacement for 1996-2005 Ford Taurus and 1996-2005 Mercury Sable models, including applications commonly searched as Dorman 973-534 Ford Taurus blower motor resistor and Dorman 973-534 Mercury Sable HVAC resistor kit.

This part cross-references OE-style numbers such as F6DZ19A706AA and RU402 for the same application.

What It Helps Fix

• Blower motor works on only certain speed settings
• No airflow from the HVAC vents due to resistor failure
• Intermittent blower operation caused by damaged terminals
• Heat-related melting or corrosion at the resistor connector
• Electrical resistance issues that affect cabin fan performance

Installation Notes and Tips

• Verify connector style, terminal count, and mounting hole layout before installation.
• Inspect the blower motor connector and surrounding wiring for heat damage before replacing the resistor.
• Confirm vehicle fitment for 1996-2005 Ford Taurus and 1996-2005 Mercury Sable before ordering.
• Use the included harness pigtail when the original connector shows corrosion, discoloration, or melted terminals.

Quality Assurance

Dorman manufactures replacement electrical and HVAC components for repair applications where the original part has failed from age, heat, or corrosion. Part number 973-534 is engineered as a service replacement for the listed Ford Taurus and Mercury Sable fitments.
