Dorman 973-552 HVAC Blower Motor Resistor Kit

Dorman 973-552 HVAC Blower Motor Resistor Kit

Dorman 973-552 is an HVAC blower motor resistor kit for select Mazda 5 models with automatic air conditioning and rear ventilator. It includes the resistor and a harness pigtail to address heat-related or corrosion-related failure at the original connector and resistor interface.

Key Features

• HVAC blower motor resistor kit for blower speed control repair
• Includes a replacement resistor and wire harness pigtail
• Female connector with male blade terminals
• 3-wire harness layout with 6-inch wiring harness length
• 3 mounting holes and 3 terminal positions
• Package contents include 1 blower motor resistor, 1 wire harness, and 3 butt connectors

Detailed Description

This Dorman blower motor resistor kit is built for select 2008-2010 and 2012-2015 Mazda 5 vehicles equipped with electronic control, automatic air conditioning, and rear ventilator. Part number 973-552 addresses common HVAC electrical failures by replacing the resistor and the damaged harness section together, helping restore proper blower motor speed operation in the Mazda 5 HVAC system. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Blower motor only working on certain speeds
• No airflow from the HVAC vents due to resistor circuit failure
• Intermittent fan operation caused by overheated terminals
• Corroded or heat-damaged resistor connector at the HVAC harness
• Electrical resistance issues in the blower motor speed control circuit

Installation Notes and Tips

Verify vehicle equipment before ordering: Fits 2008-2010 Mazda 5, N/A, Electronic Control; w/Automatic Air Conditioning; w/Rear Ventilator. Fits 2012-2015 Mazda 5, N/A, Electronic Control; w/Automatic Air Conditioning; w/Rear Ventilator. Inspect the connector, terminals, and surrounding HVAC wiring for heat damage before installation. Use the included butt connectors to splice the harness pigtail as needed, and confirm secure terminal engagement after installation. Part number 973-552 is intended for direct replacement on the listed Mazda 5 configurations.

Quality Assurance

Dorman supplies replacement electrical and HVAC components engineered to match the original service function on specific vehicle applications. This kit combines the resistor and harness repair components needed to address a failed blower motor resistor circuit on the listed Mazda 5 models.
