Four Seasons 20102 Resistor Block Overview

The Four Seasons 20102 resistor block is an HVAC blower motor resistor built for fixed speed control in the blower circuit. It is a direct-fit style replacement for select Toyota applications, including Toyota Supra and Toyota Celica models listed below.

Four Seasons Resistor Block components are focused on restoring proper blower motor operation by matching the electrical resistance needed for specific fan speeds. This part number, 20102, is a practical choice when the blower works on some speeds but not others.

Key Features

  • Brand: Four Seasons
  • Part number: 20102
  • HVAC blower motor resistor for fixed speed #4
  • Female connector with rectangular shape
  • 5 terminals with spade terminal type
  • Meets or exceeds OEM requirements
  • Resistor Block product line

Detailed Description

This Four Seasons 20102 resistor block is used in the HVAC blower motor circuit to regulate blower speed through resistance control. The rectangular female connector and 5-terminal spade design support a direct electrical interface in the vehicle’s HVAC system. For buyers searching for a Toyota Supra blower motor resistor or Toyota Celica HVAC resistor block, this part number 20102 matches the listed applications and restores the fixed #4 blower speed function.

This part cross-references A07936 and E1145A for the same application.

What It Helps Fix

  • Blower motor speed 4 not working
  • Intermittent cabin fan operation
  • Loss of one or more HVAC fan speeds
  • Overheated or failed blower resistor circuit
  • Poor cabin airflow control from the dash HVAC system

Installation Notes and Tips

Verify the connector shape, terminal count, and speed designation before installation. Confirm the vehicle application against the listed fitment for 1986 Toyota Celica and 1986-1992 Toyota Supra. Inspect the blower motor connector and surrounding HVAC wiring for heat damage or corrosion before replacing the resistor block. Proper diagnosis of the blower switch and motor circuit helps ensure the new resistor operates as expected.

Quality Assurance

Four Seasons lists this resistor block as meeting or exceeding OEM requirements, supporting OE-style fitment and electrical performance for the specified Toyota applications.
