What It Helps Fix

• Incorrect cabin temperature output
• HVAC air stuck on hot or cold
• Blend door movement problems
• Loss of temperature control at the dash
• Inconsistent airflow temperature in dual zone systems

Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC position before ordering. Confirm whether the application is Left Main, Main, or Right Main, since fitment varies by configuration. Access to the actuator is typically behind the dash HVAC housing, and the replacement should be matched to the original connector and mounting style before installation.
