Swing Louver Description

WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.

The swing louver is installed on the center vent and operates the right and left air distribution fins to send airflow evenly.

Structure

The swing louver consists of a swing switch, swing louver motor, a bar, two sliders, and two louvers.

Mechanical operation

When the swing motor rotates, the protrusion on the motor plate rotates.
The protrusion on the motor plate moves within a groove on the bar.
The fins of the louver move right and left because the bar, slider, and louver are synchronized.
