Keep every fan speed working and cabin comfort dialed in with the Standard Ignition Blower Motor Resistor RU-90. It drops in as a direct-fit replacement for the 1986-1992 Toyota Supra, and is specifically designed for Toyota applications. The blower motor resistor steps down voltage to the blower motor to set its lower and mid-range fan speeds; when a resistor fails, you often lose those speeds while high may still work — if a failed resistor is the cause, this part replaces it.

This part cross-references / interchanges with the following part numbers:
What vehicle does the RU-90 fit?
It is a direct-fit replacement for the 1986-1992 Toyota Supra. Check the Buyer's Guide tab to confirm the fit for your specific vehicle.
What does a blower motor resistor do?
It steps down voltage to the blower motor to set its lower and mid-range fan speeds, giving you variable speed control for the A/C and heater.
Why did I lose some of my fan speeds?
A failed blower motor resistor commonly causes the loss of one or more lower fan speeds while high speed may still work. If the resistor is the cause, this part replaces it.
What connectors does the RU-90 use?
It uses premium copper electrical connectors for more precise resistance values, which supports consistent performance and longer part life.
Which part numbers does this resistor cross to?
It interchanges with RU847, JA1325, BR60, 1468104300, and 8713824030.
