Overview
Dorman 973-629 is a direct replacement HVAC blower motor resistor for select Mazda CX-9 applications. It restores proper blower speed control when the original resistor fails and helps return normal heating and cooling operation.
Key Features
- Direct replacement design for the original resistor assembly.
- Matches original equipment operation and performance on supported applications.
- Rectangular connector with 4-wire, 4-terminal configuration.
- Two-bolt mounting layout for a secure installation.
- Package contents include the blower motor resistor and instructions.
Detailed Description
This HVAC blower motor resistor is built for select Mazda CX-9 models and is engineered to restore fan speed control when the factory resistor burns out or stops regulating airflow correctly. The Dorman 973-629 uses a rectangular female connector, blade-style terminals, and a 4-wire layout to match the original electrical setup on the listed vehicles. It is a practical replacement for drivers dealing with inconsistent cabin airflow, limited fan speeds, or a blower motor that only works on certain settings. This part cross-references Four Seasons 20535 for the same application.
Fits 2008-2010 Mazda CX-9, N/A. Fits 2007 Mazda CX-9, N/A, from 12/01/06.
Common Uses
- Restores blower speed control when the resistor has failed.
- Addresses loss of one or more fan speeds.
- Helps correct weak or inconsistent cabin airflow.
- Supports proper HVAC heating and cooling function.
Installation Notes
Verify connector shape, terminal style, and bolt-hole layout before installation. This part does not include wiring harness or mounting hardware. Follow the included instructions and confirm vehicle build date for the 2007 Mazda CX-9 application.
Quality Assurance
Dorman supplies this resistor as a direct replacement part intended to match original equipment operation on the listed applications.
