The resistor that sets your heater and A/C fan speeds is a small part with a big job, and the Standard Ignition Blower Motor Resistor RU-687 is built for it. It is a direct-fit replacement for the listed applications: the 1991-1993 Dodge D150, Dodge D250, Dodge D350, Dodge W150, Dodge W250, Dodge W350 and Dodge Ramcharger.
This HVAC blower motor resistor regulates the current sent to the blower motor, which gives the heater and A/C fan its variable speed settings. A blower that runs only on high or skips certain speeds is a sign this part may need replacing. If a failed resistor is the cause, this unit replaces it.
- Copper electrical connectors: Premium copper connectors support more precise resistance values. This improves resistor performance and is intended to give a longer part life.
- Built for HVAC integration: Standard Ignition's research and design process aims for seamless integration with the vehicle's HVAC system.
- Variable speed control: Designed to restore A/C and heater blower motor variable speed control, helping optimize HVAC performance and passenger comfort.
- Dodge-specific and tested: Designed specifically for Dodge applications and put through extensive testing at the manufacturer's facility.
