Product Details
This Dorman 973-150 blower motor resistor kit is built for vehicles that have lost cabin fan speed control due to heat-related resistor failure or connector deterioration. It is a practical repair for Lexus GX470, RX350, RX400h, RX330, and Toyota 4Runner models where the original resistor assembly has overheated or the harness pigtail has been damaged. This part cross-references OE-style numbers such as 4P1488 and RU342 for the same application.
Common Problems It Can Solve
- Blower motor works on only one speed
- Intermittent HVAC fan operation
- Burned, melted, or corroded resistor connector
- Loss of lower fan speeds in the cabin HVAC system
- Heat-damaged wiring at the blower resistor connector
Installation Notes and Tips
Verify connector style, terminal count, and mounting-hole layout before installation. This kit uses a 4-wire harness with blade terminals and a female connector, so matching the original configuration is important for proper repair. Inspect the blower motor connector and surrounding wiring for heat damage before installing the new resistor and pigtail.
Quality Assurance
Dorman replacement electrical components are built to address common failure points found in original HVAC resistor assemblies. For buyers searching for a Dorman 973-150 replacement for Lexus GX470 or Toyota 4Runner blower motor resistor repair, this kit provides the resistor and harness needed to restore blower speed control on the listed vehicles.
