Without Air Conditioning

Flow Through Ventilation System (typical):

GENERAL DESCRIPTION
The base heater system is designed to provide heating, ventilation, windshield defrosting, and side window defogging.

The power-vent, heat, and defrost provisions of the base heater system are controlled within the heater module. The module itself is composed of two (2) components - a blower air inlet and a heater defroster.

The blower air inlet is mounted to the front of the cowl and the heater defroster assembly is mounted to the rear of the cowl. A gasket is used between the two to prevent air, water, and noise entrance into the passenger compartment.

Air distribution is through a heater outlet, defroster duct, and power-vent duct work and outlets.
