Restore variable fan-speed control to your climate system with the Standard Ignition HVAC Blower Motor Resistor RU-554. This resistor steps the current feeding the blower motor so the fan can run at its lower and mid-range settings, and it drops in as a direct-fit replacement for the 1998-1999 Acura SLX, 1999-2002 Isuzu Trooper, and 1999-2001 Isuzu Vehicross. If a failed resistor is the reason your blower only works on high (or not at all), this replaces it.
- Premium copper connectors: used to deliver more precise resistance values, helping resistor performance and part life.
- Variable-speed control: restores A/C and heater blower motor variable speed control, helping optimize HVAC performance and passenger comfort.
- Application-matched design: specifically designed for Acura and Isuzu applications, with a research and design process aimed at seamless integration with the vehicle's HVAC system.
- Tested performance: undergoes extensive testing at the facility to help ensure correct performance across conditions.
A blower that runs only on certain speeds, or that quits entirely, is a common sign the resistor may need replacing — diagnose the cause before installing.

Frequently Asked Questions
What does the RU-554 blower motor resistor do?
It adds resistance in the blower motor circuit to control the fan's lower and mid-range speeds, allowing variable A/C and heater blower speed control.
Which vehicles does this resistor fit?
It is a direct-fit replacement for the 1998-1999 Acura SLX, 1999-2002 Isuzu Trooper, and 1999-2001 Isuzu Vehicross. See the Buyer's Guide tab to confirm your vehicle.
My blower only works on the highest setting — is this the fix?
A blower that runs only on high or certain speeds is a common sign of a failed resistor. If the resistor is the cause, this part replaces it; diagnose the circuit first.
What connectors does the RU-554 use?
It uses premium copper electrical connectors, which the manufacturer states help deliver more precise resistance values for improved performance and part life.
What interchange numbers does this resistor replace?
It cross-references 8970831360, 8970831361, 8972345450, RU1247, JA1294, and BR457.
