Designed to restore variable blower speed control to your front heater and A/C system, the Standard Ignition Blower Motor Resistor RU-312 is a direct-fit replacement for the 1984-1989 Toyota Van and the 1988 Toyota Van Wagon. See the Buyer's Guide tab for engine details.
The blower motor resistor regulates the voltage sent to the blower motor. This is what lets the heater and A/C fan run at its lower speed settings, which helps with HVAC performance and passenger comfort.
- Copper electrical connectors: Standard Ignition uses premium copper connectors for more precise resistance values. These are intended to improve resistor performance and extend part life.
- HVAC integration: Standard Ignition's research and design process aims for seamless integration with the vehicle's HVAC system.
- Toyota-specific design: Developed specifically for Toyota applications.
- Tested in-house: Goes through extensive testing at the manufacturer's facility to confirm correct performance in all conditions.
Signs this part may need replacing include a blower that runs only on its highest setting, one or more fan speeds that no longer work, or a blower that does not run at all. A faulty switch, wiring, or motor can cause similar symptoms, so diagnose the blower circuit before replacing the resistor.
