Housing Assembly HVAC: Description and Operation

Heater Module:

The G carline heater-ventilation system provides heater, defroster, and ventilation operation. The ventilation system provides ambient air to the passenger compartment by two methods (power upper, ram lower). The right and left vents are controlled by cables, which open or close the vent valves. In the open position, air only flows through the heater module inlet duct and vent ducts by means of car motion (ram air).
