Designed to restore variable fan speeds to your heater and A/C, the Standard Ignition RU991 Toyota Avalon blower motor resistor is a direct-fit replacement for the 1995 and 1997-1998 Toyota Avalon and the 1992-1996 Lexus ES300. See the "Vehicles it fits" section for engine details.
An hvac blower motor resistor sets the blower fan's lower speed settings by routing current through different resistance values. Signs this part may need replacing include a blower that runs only on its highest setting or a fan that skips one or more speeds. The switch, wiring and motor can cause similar symptoms, so diagnose the cause before replacing.

Will this 1998 Toyota Avalon blower motor resistor fit my car?
RU991 is listed for the 1995 and 1997-1998 Toyota Avalon and the 1992-1996 Lexus ES300. Check the "Vehicles it fits" section for engine details.
What does a blower motor resistor do?
It sets the blower fan's lower speed settings by routing current through different resistance values. This gives the heater and A/C fan variable speed control.
What are signs the resistor may need replacing?
A blower that runs only on its highest setting, or one that skips speeds, can indicate a failed resistor. The switch, wiring and motor can cause similar symptoms, so diagnose the cause first.
Why does RU991 use copper connectors?
Its premium copper electrical connectors are designed to hold more precise resistance values. They are intended to improve resistor performance and extend part life.
Which part numbers does RU991 interchange with?
It interchanges with RU1680, JA1994, BR890, 8875006010 and 8875033010.
