Detailed Product Overview
This Dorman HVAC blower motor resistor kit, part number 973-133, is built for 2003-2008 Toyota Corolla and 2003-2008 Toyota Matrix vehicles. It addresses common blower speed control failures caused by heat damage, corrosion, or connector wear at the resistor circuit. By replacing both the resistor and the harness pigtail, 973-133 helps restore proper electrical contact at the HVAC blower motor resistor location.
This part cross-references OE-style applications such as 3A1279 and RU389 for the same vehicle coverage. For buyers searching for a Toyota Corolla blower motor resistor, Toyota Matrix blower resistor, or Dorman 973-133 HVAC resistor kit, this listing matches the confirmed fitment shown below.
What It Is Used For
- Loss of one or more blower fan speeds
- Intermittent HVAC fan operation
- Burned, overheated, or corroded resistor connector
- Electrical resistance issues at the blower motor resistor circuit
- HVAC fan control problems in the cabin
Installation Notes and Tips
Verify connector style, terminal count, and mounting-hole layout before installation. Inspect the blower motor connector and surrounding wiring for heat damage or corrosion, since a damaged pigtail can contribute to repeat failure. Confirm fitment for 2003-2008 Toyota Corolla and 2003-2008 Toyota Matrix before replacing the resistor assembly.
- Fits 2003-2008 Toyota Corolla, N/A
- Fits 2003-2008 Toyota Matrix, N/A
Quality Assurance
Dorman replacement electrical components are engineered to match the original service function for the listed vehicles. Part number 973-133 is built as a service replacement for confirmed Toyota Corolla and Toyota Matrix applications, with the resistor and harness pigtail supplied together for the repair.
