Universal Air SW11686C HVAC Blower Motor Resistor

HVAC Blower Motor Resistor for Honda and Acura

Universal Air SW11686C is an HVAC blower motor resistor for vehicles with manual fan-speed control. It regulates blower motor voltage so the cabin fan can operate at the selected speeds, helping restore consistent airflow in the heating and air conditioning system.

Compatible with 2014-2020 Acura MDX, 2017-2021 Honda Pilot, 2019-2020 Honda Passport, and 2017-2020 Honda Ridgeline, this blower resistor is a direct-fit service part for common HVAC blower speed concerns. The SW11686C part number is also useful when searching for a replacement by application.

How This Blower Resistor Works

The blower resistor controls the electrical current sent to the blower motor, allowing the HVAC system to produce multiple fan speeds instead of only one setting. When the resistor fails, the cabin fan may stop working on certain speeds or operate inconsistently. Universal Air SW11686C is built for the listed Honda and Acura applications, including Honda Pilot, Honda Ridgeline, and Acura MDX models.

Common Problems It Can Address

• Blower fan works on only one speed
• Fan speeds 1, 2, or 3 do not operate
• Intermittent cabin airflow from the vents
• HVAC fan stops responding at the control switch
• Uneven heating or cooling output caused by blower speed loss

Installation Notes

Confirm the vehicle uses the correct HVAC blower motor resistor configuration before installation. Compare the original part to SW11686C and verify connector style, mounting points, and application details for your specific Acura MDX, Honda Pilot, Honda Passport, or Honda Ridgeline. If the blower motor has signs of overheating or electrical damage, inspect the full HVAC circuit during service.

Quality Assurance

Universal Air supplies HVAC service components for application-specific replacement needs. SW11686C is listed for the model years shown above and should be matched to the vehicle’s original blower resistor setup before installation.
