Get your fan speeds back under control with the Standard Ignition HVAC Blower Motor Resistor RU-768. This resistor sets the blower motor's variable fan speeds, so the heater and A/C fan responds correctly at each position on the climate control switch. It's a direct-fit replacement for the 2006-2009 Subaru Legacy and 2005-2009 Subaru Outback — specifically designed for Subaru applications.
- Premium copper connectors: Uses premium copper electrical connectors for more precise resistance values, which improves resistor performance and supports a longer part life.
- Restores variable speed control: Brings back A/C and heater blower motor variable speed control, helping to optimize HVAC performance and passenger comfort.
- Seamless integration: The research and design process leads to seamless integration with the vehicle's HVAC system.
- Tested performance: Undergoes extensive testing at the manufacturer's facility to help ensure correct performance in a range of conditions.
If your blower only runs on one speed (often high) or drops certain speeds, a failed resistor may be the cause — if so, this part replaces it. See the Buyer's Guide tab for the full engine-level fitment.

Frequently Asked Questions
What does the RU-768 blower motor resistor do?
It provides the resistance that sets the blower motor's different fan speeds, so the heater and A/C fan responds correctly at each position on the climate control switch.
Which vehicles does this resistor fit?
It's a direct-fit replacement for the 2006-2009 Subaru Legacy and 2005-2009 Subaru Outback. Check the Buyer's Guide tab to confirm fitment for your vehicle.
My blower only works on high speed — is this the part I need?
That symptom can point to a failed blower motor resistor. If the resistor is the cause, this replaces it; diagnose the cause first, as wiring or the switch can also be involved.
What numbers does the RU-768 interchange with?
It cross-references RU1457, JA1757, BR668, and 73532AG000.
What connectors does this resistor use?
It uses premium copper electrical connectors for more precise resistance values, which helps improve resistor performance and supports a longer part life.
