Detailed Description
This HVAC blower motor resistor kit is built for vehicles that have lost one or more blower speeds due to heat damage, corrosion, or connector wear. Dorman 973-138 addresses the resistor and the harness side of the repair, helping restore reliable blower motor operation in 1989-1991 Toyota Pickup models made in Japan. This part cross-references OE-style numbers such as 3A1207 and RU246 for the same application.
Compatible With 1989-1991 Toyota Pickup, N/A. Use Dorman 973-138 when the original resistor shows signs of overheating, melted terminals, or intermittent blower performance. The part number 973-138 is a practical replacement choice for Toyota Pickup HVAC electrical repairs where the connector has also been affected.
Common Problems This Part Can Help Solve
- Blower motor works on only certain fan speeds
- No airflow from the HVAC vents at selected settings
- Intermittent blower operation caused by heat-damaged resistor circuits
- Corroded or burned electrical connector at the resistor
- HVAC fan speed control failure in the dash system
Installation Notes and Tips
Inspect the blower motor connector, resistor cavity, and surrounding wiring before installation. If the original resistor overheated, repair any damaged terminals or melted insulation so the new part can operate correctly. Confirm blade terminal orientation, mounting hole alignment, and harness routing before reconnecting the HVAC electrical circuit. Dorman 973-138 is listed for 1989-1991 Toyota Pickup applications, made in Japan.
Quality Assurance
Dorman supplies replacement electrical components engineered to address common failure points in original HVAC circuits. This kit is intended to replace a damaged resistor and harness assembly on the specified Toyota Pickup fitment.
