- 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.
