Compatible with 2001-2006 Hyundai Elantra and 2003-2008 Hyundai Tiburon, this Four Seasons HVAC mode door actuator is a direct-fit replacement for common air door control issues in these applications. The Four Seasons Air Door Actuator line focuses on accurate HVAC door operation for vehicles that rely on electronic air routing.

Detailed Description

This HVAC air door actuator is used to move the internal doors that direct airflow through the dash vents, floor outlets, or defrost outlets. In 2001-2006 Hyundai Elantra and 2003-2008 Hyundai Tiburon models, a worn or failed actuator can prevent the HVAC system from changing modes correctly. Four Seasons 73075 is built for the air door actuator position and matches the listed connector and mounting style for the specified vehicles.

This part cross-references Global Parts Distributors LLC 1711917 for the same application.

What It Helps Fix

• Airflow stuck on one vent setting
• No response when switching between panel, floor, and defrost modes
• Clicking or repeated movement from a failing HVAC actuator
• Inconsistent air direction from the climate control system
• Loss of proper mode door movement in the dash HVAC housing

Installation Notes and Tips

Verify connector style, mounting ear layout, and linkage type before installation. Access to the actuator is typically through the HVAC housing behind the dash, so trim removal may be required. After installation, cycle the climate controls through each mode setting to confirm smooth door movement and correct airflow routing.

Quality Assurance

Four Seasons is a recognized aftermarket brand for HVAC replacement components, and this actuator is built to match the listed application details for proper fitment and function in the specified Hyundai vehicles.
