Get every fan speed working again with the Standard Ignition HVAC Blower Motor Resistor RU-299, a direct-fit replacement for the 1985 Toyota Cressida. This resistor sits in the blower motor circuit and provides the stepped resistance that sets your heater and A/C fan to low and mid speeds — when it fails, you often lose one or more speeds while high may still work.
- Precise resistance values: premium copper electrical connectors help deliver more accurate resistance for consistent resistor performance and longer part life.
- Toyota-focused design: specifically designed for Toyota applications, with a research and design process aimed at seamless integration with the vehicle's HVAC system.
- Variable-speed control: if a failed resistor is the cause of your missing blower speeds, this part is designed to restore A/C and heater blower motor variable-speed control to help optimize HVAC performance and passenger comfort.
- Tested performance: undergoes extensive testing at the facility to help ensure correct performance across conditions.
Always diagnose the cause of a blower issue before replacing, as switches, wiring, and the motor itself can produce similar symptoms.

Frequently Asked Questions
What does this blower motor resistor do?
It provides stepped resistance in the blower motor circuit, setting the heater and A/C fan to its lower and middle speeds so the blower runs at variable speeds.
What vehicle does the RU-299 fit?
It is a direct-fit replacement for the 1985 Toyota Cressida. See the Buyer's Guide tab to confirm fitment for your vehicle.
Why do only some of my fan speeds work?
A failed resistor commonly causes a loss of certain low or mid fan speeds while high may still work. If the resistor is the cause, replacing it can restore those speeds.
What numbers does this part interchange with?
It cross-references RU999, JA1366, BR209, and 8863532010.
Should I diagnose before replacing the resistor?
Yes. Blower switches, wiring, and the motor itself can cause similar symptoms, so confirm the resistor is the fault before installing this replacement.
