Four Seasons 20266 HVAC Blower Motor Resistor - Front

HVAC Blower Motor Resistor Block for Variable Speed Control

Four Seasons 20266 is a resistor block for HVAC blower motor speed control in vehicles equipped with automatic temperature control or multi-zone climate systems. It uses a female rectangular connector with 4 spade terminals and is built to meet or exceed OEM requirements for direct replacement service.

For Ram ProMaster 1500, Ram ProMaster 2500, Ram ProMaster 3500, Toyota Camry, Lexus RX350, and other listed applications, this blower motor resistor helps restore proper fan operation when the HVAC system no longer changes speeds correctly. Four Seasons 20266 is the part number to reference when matching the correct resistor block for the application.

Detailed Description

This Four Seasons resistor block is used in HVAC systems that regulate blower motor speed through resistor-based control. It is listed for a wide range of vehicles, including 2020-2023 Ram ProMaster 1500, 2500, and 3500; 1998-2006 Toyota Camry; 2003-2009 Lexus GX470; and 2007-2009 Lexus RX350. The design supports variable speed operation and is specified with a rectangular female connector and four spade terminals for proper electrical interface.

Four Seasons 20266 is also referenced under several interchange numbers, including 973150, 973227, 11120266, 8716513010, A08181, JA1621, and SW11451. Use the part number and vehicle fitment details to confirm the correct HVAC blower motor resistor for your application.

What It Helps Fix

• Blower motor works only on certain fan speeds
• HVAC fan speed is stuck on one setting
• No airflow from the cabin vents due to resistor failure
• Intermittent blower motor operation
• Loss of automatic temperature control fan response

Installation Notes and Tips

• Verify the connector shape, terminal count, and terminal style before installation.
• Confirm the vehicle uses the listed HVAC configuration, including ATC or three-zone climate control where noted.
• Inspect the blower motor and related wiring for heat damage before replacing the resistor block.
• Match the application by year, make, model, and HVAC notes to avoid incorrect fitment.

Quality Assurance

Four Seasons 20266 is manufactured as an OEM-level replacement and is listed as meeting or exceeding OEM specifications for the applications shown.
