Get back your fan-speed control with the Standard Ignition HVAC Blower Motor Resistor RU-255. This resistor manages the blower motor's variable fan speeds, dropping voltage to the motor so you can select low and medium settings instead of only high. It's a direct-fit replacement for the 1985-1986 Toyota MR2 — see the Buyer's Guide tab for engine-level fitment. When a blower resistor fails, the fan often works only on the highest setting or quits on certain speeds; if a failed resistor is the cause, this RU-255 replaces it.
- Premium copper connectors: help deliver more precise resistance values for consistent resistor performance and longer part life.
- Seamless HVAC integration: the result of Standard's research and design process, so it works with the vehicle's heating and cooling system.
- Variable-speed control: handles A/C and heater blower motor speed steps to support proper HVAC operation and cabin comfort.
- Toyota-specific design: engineered for Toyota applications and tested extensively for correct performance across conditions.

Frequently Asked Questions
What does this blower motor resistor do?
It drops voltage to the HVAC blower motor to set its variable fan speeds, letting you choose low and medium settings instead of only high.
What vehicle does the RU-255 fit?
It's a direct-fit replacement for the 1985-1986 Toyota MR2. Check the Buyer's Guide tab to confirm the fit for your vehicle.
My fan only runs on high — is this the fix?
A blower that works only on high or loses certain speeds is a common sign of a failed resistor. If the resistor is the cause, this RU-255 replaces it.
What numbers does this resistor interchange with?
It cross-references RU955, JA1313, BR165, 1468103570, and 8713817020.
What are the connectors made of?
It uses premium copper electrical connectors, which help deliver more precise resistance values for consistent performance and longer part life.
