Detailed Description

Dorman 984-539 is an HVAC blower motor resistor designed for vehicles that use a transistor-style blower control assembly. It is engineered to restore proper heating and cooling fan speed control when the original resistor has burned out or failed. This part cross-references common OE-style numbers such as 79330STXA01 and RU707 for the same application. Compatible with 2015-2017 Acura TLX and 2009-2015 Honda Pilot, this resistor is a practical replacement for drivers dealing with inconsistent cabin fan operation. The Dorman 984-539 part number is a useful reference when verifying the correct HVAC control component for your vehicle.

Common Problems It Can Solve

• Blower motor works on only one speed
• Fan speeds stop responding at the HVAC control panel
• Intermittent cabin airflow from the vents
• No heat or no A/C airflow due to blower control failure
• Burnt or overheated blower resistor assembly

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This unit uses a rectangular connector with 1 female connector and 4 male terminals, and it mounts with 2 bolt holes. No wiring harness or mounting hardware is included, so reuse or source any required vehicle-specific components as needed. Confirm the vehicle uses a transistor assembly configuration before ordering Dorman 984-539.

Quality Assurance

Dorman designs direct replacement HVAC components to match original equipment fit and function on listed applications. For Acura TLX and Honda Pilot owners, Dorman 984-539 provides a factory-style replacement option for restoring blower speed control.
