Designed to restore variable-speed control of your A/C and heater blower, the Standard Ignition Blower Motor Resistor RU-437 is a direct-fit replacement for the listed application, the 1997-1999 Acura CL. It controls the current sent to the blower motor so each fan-speed setting on the climate control can run the blower at its intended speed.
- Copper electrical connectors: Premium copper connectors are used for more precise resistance values, designed to improve resistor performance and deliver a longer part life.
- HVAC system integration: Standard Ignition's research and design process is aimed at seamless integration with the vehicle's HVAC system.
- Variable speed control: Intended to restore A/C and heater blower motor variable-speed control, helping optimize HVAC performance and passenger comfort.
- Built for Acura: Specifically designed for Acura applications and put through extensive testing at the manufacturer's facility to verify correct performance in all conditions.
How it works: The resistor steps down the voltage reaching the blower motor on the lower fan settings, which is what gives the heater and A/C more than one fan speed.
Signs this part may need replacing: the blower runs only on its highest setting, or one or more fan speeds stop working. A switch, wiring, or motor fault can cause similar symptoms, so diagnose the cause first. If a failed resistor is the cause, RU-437 replaces it.
Fitment: 1997-1999 Acura CL. See the Buyer's Guide tab for engine details.
