Intake Door Control

Intake door motor is located on upper part of intake unit. It opens and closes intake door with a rod and a link. When MAX A/C switch is on (REC position on heater control panel), the ground circuit of intake door motor is switched to terminal No. 2 from terminal No. 1. Motor starts to rotate as position switch contacts built into it are set to current flow position. Contacts turn along with motor. When they reach non-contact flow position, motor will stop. Motor always turns in same direction.
