Air Distributor Duct
DUCTS AND OUTLETS
Control of airflow through the HVAC module is regulated by vacuum-actuated doors. Outside air is either cooled or heated and then discharged
according to control setting.
A system of ducts and outlets directs air to the passenger compartment. In cases of poor air output, defroster, heater, air conditioning, and vent ducts
should be checked for obstructions such as leaves, dirt, or objects which may have fallen into the ducts from the passenger compartment.
