Help bring back variable heater and A/C fan speeds with this Standard Ignition blower motor resistor, part number RU-81, a direct-fit replacement for the 1987-1991 Toyota Camry and 1988-1989 Toyota Celica. The resistor controls the current sent to the blower motor so the fan can run at the speed you select. Standard Ignition designed this HVAC blower motor resistor specifically for Toyota applications. See the Buyer's Guide tab for engine details.
Signs this part may need replacing include a blower that runs only on its highest setting, or one or more fan speeds that no longer respond. If a failed resistor is the cause, the RU-81 replaces it. Diagnose the fault before replacing parts, because the fan switch, wiring or the blower motor itself can cause similar symptoms.

Is this the right Toyota Camry blower motor resistor for a 1987-1991 Toyota Camry?
Yes. It is a direct-fit replacement for the 1987-1991 Toyota Camry and the 1988-1989 Toyota Celica. See the Buyer's Guide tab for engine details.
What does a blower motor resistor do?
It controls the current sent to the blower motor so the heater and A/C fan can run at the different speeds you select.
What are signs the blower motor resistor may need replacing?
Common signs include a fan that works only on its highest setting, or speeds that no longer respond. Diagnose the fault first, because the switch, wiring or motor can cause similar symptoms.
Why does the RU-81 use copper connectors?
Standard Ignition uses premium copper electrical connectors to provide more precise resistance values. The company says this improves resistor performance and gives the part a longer life.
Is the RU-81 tested by the manufacturer?
Yes. Standard Ignition puts the resistor through extensive testing at its facility to verify correct performance, and it designed the part specifically for Toyota applications.
