Dorman 973-573 HVAC Blower Motor Resistor Kit

HVAC Blower Motor Resistor Kit for Manual Climate Control

Dorman 973-573 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor on select Volkswagen and Audi vehicles with manual temperature control. It includes the resistor and a harness pigtail to restore blower speed control and help correct intermittent fan operation.

• Direct replacement HVAC blower motor resistor kit for manual temperature control systems
• Includes a replacement resistor and wiring harness pigtail
• Blade-style terminals with a 4-wire, 4-connector design
• Male connector and terminal configuration
• Gasket or seal included for the installation interface
• 11.8-inch wiring harness length
• Mounting hole quantity: 2

Detailed Product Overview

This Dorman 973-573 blower motor resistor kit is built for vehicles that use manual HVAC fan-speed control, including applications such as the Volkswagen Beetle, Volkswagen Golf, Volkswagen Jetta, Audi TT, and Audi TT Quattro. It addresses common resistor failures caused by heat damage or corrosion at the original connector, helping restore proper blower motor speed selection across the HVAC range.

This part cross-references Standard Ignition RU-429 and Beck/Arnley 204-0048 for the same application. It is also listed with interchange references including 1J0819022.

What It Helps Fix

• Blower motor only working on certain speeds
• No fan operation at one or more HVAC settings
• Intermittent cabin airflow from the vents
• Heat-damaged or corroded resistor connector
• Electrical resistance issues in the blower control circuit

Installation Notes and Tips

Verify manual temperature control before ordering, since this resistor kit is not for automatic climate control systems. Confirm connector style, terminal count, and harness routing against the original part before installation. Fitment includes 1998-2010 Volkswagen Beetle, 1999-2007 Volkswagen Golf, 2000-2004 Volkswagen Jetta, 1999-2006 Audi TT, 2000-2006 Audi TT Quattro, and other listed Volkswagen applications with manual temperature control. For 2005 Volkswagen Jetta, fitment is limited to vehicles up to VIN 9M-5-149 999.
