Take back control of your fan speeds with the Standard Ignition HVAC Blower Motor Resistor RU-251. This resistor meters current to the blower motor so the fan can run at its lower and mid-range settings, and it drops in as a direct-fit replacement for the 1981-1987 Toyota Corolla. If a failed resistor is why your blower only works on high — or won't run at all on certain speeds — the RU-251 replaces the worn original.
- Premium copper connectors: uses premium copper electrical connectors for more precise resistance values, improving resistor performance and offering longer part life.
- Restores variable speed control: designed to restore A/C and heater blower motor variable-speed control, helping optimize HVAC performance and passenger comfort.
- Built to integrate: Standard Ignition's research and design process leads to seamless integration with the vehicle's HVAC system.
- Tested for the application: specifically designed for Toyota applications and put through extensive facility testing to confirm correct performance in all conditions.

Frequently Asked Questions
What does this blower motor resistor do?
It provides resistance in the blower motor circuit to control the fan's lower and mid-range speeds, so you can select settings below high.
Will it fit my vehicle?
It is a direct-fit replacement for the 1981-1987 Toyota Corolla. Check the Buyer's Guide tab to confirm it matches your vehicle.
My blower only works on high speed — will this fix it?
A blower that runs only on high is a common sign of a failed resistor. If the resistor is the cause, the RU-251 replaces it; diagnose the circuit first.
What numbers does the RU-251 replace?
It cross-references RU951, JA1302, BR161, 1468101560, and 8713812091.
What are the electrical connectors made of?
It uses premium copper electrical connectors, which help provide more precise resistance values for better performance and longer part life.
