Four Seasons Resistor Block 20201

The Four Seasons 20201 resistor block is an OE-style HVAC blower motor resistor for vehicles that use a fixed 3-speed blower control. It is built with a female rectangular connector, 4 spade terminals, and meets or exceeds OEM requirements for direct replacement service.

Compatible with 1983-1986 Toyota Tercel and 1984-1985 Toyota Corolla applications that use a resistor block, this part supports consistent blower motor speed control in the HVAC system. Four Seasons Resistor Block 20201 is a practical replacement when the original resistor has failed or the cabin fan no longer responds correctly at lower speeds.

Key Features

  • Four Seasons Resistor Block, part number 20201
  • HVAC blower motor resistor for fixed #3 speed control
  • Female rectangular connector with 4 spade terminals
  • Meets or exceeds OEM specifications
  • Direct-fit replacement for select Toyota Tercel and Toyota Corolla models

Product Details

This resistor block is used in the HVAC blower circuit to regulate fan speed through the vehicle’s control switch. For Toyota Tercel and Toyota Corolla models listed below, the Four Seasons 20201 helps restore proper blower operation when one or more fan speeds stop working. This part cross-references TY8713816100 and 8713816100 for the same application.

What It Helps Fix

  • Blower motor only works on one speed
  • Lower fan speeds do not operate
  • Intermittent HVAC fan speed control
  • Cabin airflow that changes unpredictably
  • Failed resistor block in the heater and A/C control circuit

Installation Notes and Tips

Verify the connector shape, terminal count, and vehicle application before installation. Match the original resistor block configuration to the existing HVAC harness on your Toyota Corolla or Toyota Tercel, and inspect the blower motor circuit for heat damage or corrosion that may have contributed to the failure. Confirm the replacement part number 20201 against the original unit when servicing the HVAC system.

Quality Assurance

Four Seasons identifies this resistor block as meeting or exceeding OEM requirements, making it a direct replacement option for repair work on select Toyota HVAC systems. The Four Seasons 20201 is built for the specified application and connector layout.
