My re-circulation light comes on but it still pulls air from outside. I need to know the location of the actuator to replace.

Welcome to 2CarPros.

I attached the directions for removal and replacement. The directions indicate automatic climate control. However, the recirculation actuator is the same as manual. The attached pictures correlate with the directions.
