Universal Air SW11431C is an HVAC blower motor resistor for select Mazda 3 models. It is used to control blower motor speed in vehicles with manual HVAC blower control, helping restore proper fan operation when the resistor has failed.

Key Features

• HVAC blower motor resistor for select Mazda 3 applications
• Direct-fit replacement for manual blower speed control systems
• Supports multiple fan speeds through the HVAC circuit
• Universal Air Blower Resistor product line
• Part number SW11431C for application lookup and ordering

Detailed Description

This Universal Air blower resistor is built for 2004-2005 Mazda 3 and 2006-2009 Mazda 3 models. It is not compatible with Automatic Temperature Control systems on 2006-2009 Mazda 3 applications, so confirm the HVAC control setup before ordering. For buyers searching for a Mazda 3 blower resistor, HVAC blower motor resistor, or SW11431C replacement, this part matches the listed manual-control applications.

The Universal Air Blower Resistor line focuses on HVAC electrical control components used to regulate blower motor speed. In this application, SW11431C helps restore normal fan-speed selection when the original resistor has worn out or failed.

Common Issues It Can Help Solve

• Blower motor works only on one speed
• Lower fan speeds stop functioning
• Intermittent cabin airflow from the vents
• No response from the HVAC fan speed selector
• Resistor failure in manual climate control systems

Installation Notes and Tips

Verify the vehicle is a 2004-2005 Mazda 3 or a 2006-2009 Mazda 3 with manual HVAC controls before installation. On 2006-2009 Mazda 3 models, this part does not work with Automatic Temperature Control systems. Inspect the blower motor connector and related wiring for heat damage or corrosion before replacing the resistor, since electrical damage can affect the new part.

Quality Assurance

Universal Air supplies HVAC replacement components for vehicle repair applications. Part number SW11431C is cataloged for the listed Mazda 3 fitments and should be matched to the vehicle’s HVAC control type for correct application.
