Heater Control Panel
WARNING: This page is about a different car, the 2001 Hyundai Accent and 2000 Hyundai Accent. However, it is still accessible from the selected car via links, so may be relevant.
Heater control panel uses vacuum motors to control positions of blend doors. A fresh air/recirculated air selector button or lever is used to control airflow source (fresh or recirculated). Airflow selector directs airflow to desired outlet. Temperature selector opens or closes blend-air door, which determines heat output. See Fig 1.
