Four Seasons 20482 HVAC Blower Motor Resistor

Four Seasons 20482 Resistor Block Overview

The Four Seasons Resistor Block, part number 20482, is an HVAC blower motor resistor for vehicles with variable blower speed control. It uses a square female connector with 5 terminals to manage blower motor speed through the HVAC circuit.

Fits 2008-2011 Lincoln Town Car, motor resistor. Fits 2003-2007 Lincoln Town Car, compatible with HVAC systems featuring Automatic Temperature Control (ATC).

Key Features

• Four Seasons Resistor Block for HVAC blower motor speed control
• Part number 20482 for direct reference during ordering and service lookup
• Female square connector with 5 terminals
• Variable-speed operation for HVAC blower control
• Switch-style resistor block construction

Product Details

This resistor block is used in HVAC systems to regulate blower motor speed by controlling current flow through the fan circuit. The Four Seasons 20482 is listed for Lincoln Town Car applications and is referenced for 2008-2011 models as a motor resistor, with 2003-2007 Lincoln Town Car coverage for systems equipped with Automatic Temperature Control (ATC). The 20482 part number is also cross-referenced to UAC SW11414C for the same application.

Four Seasons’ Resistor Block line focuses on HVAC electrical control components used in blower speed circuits. For service work on a Lincoln Town Car, this line provides a direct-fit style replacement path when the original resistor block has failed or the blower no longer responds correctly at one or more speed settings.

Common Issues This Part May Resolve

• Blower motor works only on certain speed settings
• HVAC fan speed is stuck on one setting
• Cabin airflow drops because the blower resistor has failed
• Automatic Temperature Control blower operation becomes inconsistent
• No response from the HVAC blower motor speed circuit

Installation Notes

Verify the connector shape, terminal count, and HVAC system type before installation. This part uses a female square connector with 5 terminals, so matching the electrical connector and vehicle application is important for proper fitment. Confirm the vehicle is a Lincoln Town Car within the listed year range and, for 2003-2007 models, that the HVAC system uses Automatic Temperature Control (ATC).

Quality Assurance

Four Seasons supplies HVAC replacement components for service applications, and this resistor block is cataloged for the specified Lincoln Town Car fitments. Always confirm part number 20482 against the original component and vehicle build details before installation.
