Get your heater and A/C fan working through its speed settings again with the Standard Ignition Blower Motor Resistor RU-435, a heater resistor for the 1986-1987 Honda Civic that also fits the 1986-1987 Honda Wagovan and 1986-1987 Acura Integra. It is a direct-fit replacement for the listed applications and is specifically designed for Honda/Acura vehicles.
This hvac blower motor resistor controls how much current reaches the blower motor, which gives the fan its separate speed settings. If a failed resistor is why your fan runs only on high or skips speeds, this unit is designed to restore variable speed control for the A/C and heater blower.
- Copper electrical connectors: Standard Ignition uses premium copper connectors for more precise resistance values. These are intended to improve resistor performance and offer a longer part life.
- HVAC integration: Standard Ignition's research and design process aims for seamless integration with the vehicle's HVAC system.
- Comfort-focused: Helps optimize HVAC performance and passenger comfort by bringing back variable blower speed control.
- Tested: Extensively tested at Standard Ignition's facility for correct performance in all conditions.
A blower motor resistor may need replacing if the fan works only on the highest setting, if low or middle speeds are missing, or if the blower does not run on some settings. Switches, wiring and the blower motor itself can cause similar symptoms, so diagnose the cause before replacing parts. See the Buyer's Guide tab for full fitment details.
