Bring back full fan-speed control on your Toyota's climate system with the Standard Ignition HVAC Blower Motor Resistor RU-90 (also written RU90). It drops in as a direct-fit replacement for the 1986-1992 Toyota Supra, restoring the A/C and heater blower motor's variable-speed operation to help optimize HVAC output and passenger comfort. The blower resistor sets the voltage the fan motor receives, giving you the low and mid speeds between off and high — when it fails, you often lose one or more of those intermediate settings.
If a failed blower motor resistor is the cause of your missing fan speeds, this replaces it. Confirm fitment for your Supra before ordering.

This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It sets the voltage sent to the HVAC blower motor, providing the low and mid fan speeds between off and high for the heater and A/C system.
Which vehicles does the RU-90 fit?
It is a direct-fit replacement for the 1986-1992 Toyota Supra. See the Buyer's Guide tab and confirm fitment for your vehicle before ordering.
Why does my blower only work on high speed?
That is a common sign the blower motor resistor may have failed. If the resistor is the cause, the RU-90 replaces it, though other components can also affect fan speeds.
What numbers does this part interchange with?
It cross-references RU847, JA1325, BR60, 1468104300, and 8713824030.
What are the connectors made of?
Standard uses premium copper electrical connectors to deliver more precise resistance values, supporting improved resistor performance and longer part life.
