When your Toyota's fan quits working on some settings, the Standard Ignition HVAC Blower Motor Resistor RU-273 puts the blower motor's variable-speed control back in play. It installs as a direct-fit replacement for the 2001-2003 Toyota Highlander [All], dropping into the blower circuit to set the resistance that lets the fan run at its lower speeds.
A blower resistor adds resistance in the motor's power path so the fan can turn at reduced speeds instead of only high; if a failed resistor is the reason your HVAC fan works only on certain settings, this replaces it. Standard Ignition builds the RU-273 for Toyota applications and tests it before it ships.
- Premium copper connectors: used for more precise resistance values and longer part life.
- Terminals: 4 male blade terminals in a rectangular female connector with a single connector cavity.
- 12-volt, 3-5 speed: designed to work with the vehicle's HVAC system.
- Mounting: screw-attached; no wiring harness, mounting bracket, or hardware included.

Frequently Asked Questions
What does this blower motor resistor do?
It adds resistance in the blower motor's circuit so the fan can run at its lower speeds. If a failed resistor is why your fan works only on some settings, this replaces it.
What vehicles does the RU-273 fit?
It is a direct-fit replacement for the 2001-2003 Toyota Highlander [All]. See the Buyer's Guide tab to confirm it matches your vehicle.
What are the signs the resistor may need replacing?
Common signs are the blower running only on the highest speed or losing one or more lower fan speeds. Diagnose the cause before replacing, as other components can produce the same symptom.
Is a wiring harness or mounting hardware included?
No. The RU-273 ships without a wiring harness, mounting bracket, or hardware. Consult the vehicle service information for the correct fasteners and whether they may be reused.
How many terminals and speeds does it support?
It has 4 male blade terminals in a rectangular female connector with one connector cavity, is rated 12 volts, and is built for 3-5 speed HVAC systems.
