Four Seasons 20461 HVAC Blower Motor Resistor

Four Seasons 20461 Resistor Block Overview

The Four Seasons 20461 resistor block is an HVAC blower motor resistor for vehicles equipped with air conditioning. It controls blower motor speed selection through a fixed #4 speed circuit and uses a 5-terminal male connector layout for direct electrical interface.

Built under the Four Seasons Resistor Block line, this component is focused on restoring proper blower motor operation in select Dodge truck and utility applications. If your system has lost one or more fan speeds, this resistor block is the electrical control point to inspect.

Detailed Description

Four Seasons 20461 is an HVAC blower motor resistor used to regulate blower speed in compatible Dodge applications. It is listed for 1991-1993 Dodge D150, D250, D350, Ramcharger, W150, W250, and W350 models equipped with air conditioning. This part number is also referenced as 20461 in interchange listings for related service applications.

For buyers searching for a Dodge D150 blower motor resistor, Dodge Ramcharger HVAC resistor block, or Four Seasons 20461 resistor block for air-conditioned trucks, this part provides the specified terminal count and connector style needed for the application. It is a direct-fit electrical service component for the listed vehicles and should be matched to the vehicle’s HVAC connector and speed circuit requirements.

What It Helps Fix

• Blower motor works on only one speed
• One or more HVAC fan speeds are inoperative
• Intermittent cabin airflow control
• Loss of resistor-controlled blower operation
• Electrical resistance circuit failure in the HVAC control path

Installation Notes and Tips

Verify the vehicle is a 1991-1993 Dodge D150, D250, D350, Ramcharger, W150, W250, or W350 with air conditioning before ordering. Compare the 5-terminal male connector, connector shape, and speed designation to the original part before installation. Inspect the blower motor connector and surrounding HVAC wiring for heat damage or corrosion, since resistor failures often occur alongside connector wear.

For best results, confirm the replacement matches the original resistor block layout and terminal configuration exactly. If the blower motor has excessive current draw, address that condition before installing the new resistor.

Quality Assurance

Four Seasons is a recognized HVAC parts brand with a dedicated Resistor Block product line for service replacement applications. Part number 20461 is cataloged for the listed Dodge fitments and cross-references 4261113 and 56003527 for the same application.
