Dorman 973-093 HVAC Blower Motor Resistor

Restore proper cabin airflow control with this direct replacement HVAC blower motor resistor from Dorman. It is built to match the operation and performance of the original part on select Mazda applications, including Mazda 3 and Mazda 5 models.

Use Dorman 973-093 when the blower motor no longer changes speeds correctly or the HVAC system loses one or more fan settings. This replacement resistor is designed for vehicles with mechanical control systems and uses a 1-connector, 4-terminal rectangular interface for a direct-fit repair.

Key Features

  • Direct replacement HVAC blower motor resistor for select Mazda vehicles
  • Matches original equipment operation and performance
  • Rectangular connector with 1 female connector and 4 male blade terminals
  • 2 bolt holes for secure mounting
  • Package includes the blower motor resistor and instructions
  • Dorman part number 973-093 for easy identification

Detailed Description

This blower motor resistor is used to regulate blower fan speed in the HVAC system by controlling electrical current to the blower motor. When the original resistor burns out, the system can lose low, medium, or high fan settings, reducing heating and cooling control. Dorman 973-093 is a direct replacement for select 2004-2005 Mazda 3 and 2006-2010 Mazda 5 models with mechanical control, and it is built to restore normal HVAC function without changing the factory-style connection layout. This part cross-references OE-style numbers such as BP4K61B15 and RU504 for the same application.

What It Helps Fix

  • Blower motor stuck on one speed
  • Loss of one or more fan speeds
  • Intermittent HVAC blower operation
  • No cabin airflow from the vents
  • Burnt or failed blower motor resistor

Installation Notes and Tips

Verify the vehicle uses mechanical HVAC control before ordering. Confirm connector shape, terminal count, and mounting style against the original resistor before installation. Inspect the blower motor and related wiring for heat damage or corrosion, since a failed motor or damaged connector can shorten the life of the replacement resistor. Compatible with 2004 Mazda 3, 2005 Mazda 3 built to 2/15/05, and 2006-2010 Mazda 5, mechanical control.

Quality Assurance

Dorman manufactures this replacement resistor to match original equipment fit and function on the listed Mazda applications. Part number 973-093 is intended for direct replacement use on the confirmed vehicle fitments above.
