Take back control of your cabin fan with the Standard Ignition HVAC Blower Motor Resistor RU-264 (also written RU264). It drops in as a direct-fit replacement for the 1993-1995 Mazda RX-7 — see the Buyer's Guide tab for the full application details. The blower motor resistor sets the different fan speeds for your heater and A/C by adding resistance to the blower motor circuit; if a failed resistor is the cause of a blower that only works on high (or has lost one or more speeds), this part replaces it.
- Premium copper connectors: use copper electrical connectors for more precise resistance values, helping resistor performance and part life.
- Variable-speed control: designed to restore the A/C and heater blower motor's variable speed settings for improved HVAC operation and passenger comfort.
- Application-engineered: specifically designed for Mazda applications, with a research and design process aimed at seamless integration with the vehicle's HVAC system.
- Tested: undergoes extensive testing at the manufacturer's facility to verify correct performance across conditions.

Frequently Asked Questions
What does this blower motor resistor do?
It adds resistance to the blower motor circuit to set the different heater and A/C fan speeds. It's the RU-264 for the 1993-1995 Mazda RX-7.
Will this fit my vehicle?
It's a direct-fit replacement for the 1993-1995 Mazda RX-7. Check the Buyer's Guide tab to confirm the application for your vehicle.
My fan only runs on high — is this the part I need?
A blower stuck on one speed can be a failed resistor, but other causes exist. If the resistor is the cause, the RU-264 replaces it; diagnose before ordering.
What connectors does the RU-264 use?
It uses premium copper electrical connectors for more precise resistance values, which helps resistor performance and part life.
What numbers does this part cross-reference?
It interchanges with RU964, JA1161, BR174, 1468107350, and D06161B15.
