Keep every heater and A/C fan speed responding with the Standard Ignition HVAC Blower Motor Resistor RU-291. This resistor controls the current flowing to the blower motor to set its different fan speeds, and it installs as a direct-fit replacement for the 1983-1986 Toyota Camry [All]. If a failed blower motor resistor is why some fan speeds have stopped working, this replaces it.
- Precise resistance values: premium copper electrical connectors help hold resistance values accurately, supporting steady performance and part life.
- Variable speed control: handles the blower motor's stepped fan speeds (3-5 speed) to help maintain heater and A/C airflow settings.
- 12V, 4-terminal design: rectangular female connector with four male blade terminals and a single connector cavity, secured by screw attachment.
- Toyota-specific build: specifically designed for Toyota applications and tested at the facility for correct performance.

Frequently Asked Questions
What does the RU-291 blower motor resistor do?
It controls the current sent to the HVAC blower motor to produce its different fan speeds. When it fails, some speeds may stop working while others still operate.
What vehicle does the RU-291 fit?
It's a direct-fit replacement for the 1983-1986 Toyota Camry [All]. Check the Buyer's Guide tab to confirm it matches your vehicle.
What are the signs this resistor may need replacing?
Common signs include losing one or more fan speeds—often only the highest speed still works—or the blower not responding to speed changes. Diagnose the cause before replacing.
Does it include a wiring harness or mounting hardware?
No. The wiring harness, mounting bracket, and hardware are not included; consult the vehicle service information for the correct fasteners and whether they may be reused.
What are the resistor's connector specs?
It has a rectangular female connector with four male blade terminals and a single connector cavity, rated at 12 volts, and is secured by screw attachment.
