DESCRIPTION
All models use a blend-air system. Outside air enters heater through cowl opening and passes through a plenum chamber to heater core. A temperature control door in heater housing either directs incoming air through or around heater core.
Once past heater core, heated air and unheated air are mixed, producing air at desired temperature. Heater discharge is then directed through dash panel to air distribution duct in passenger compartment.
Vans may have optional auxiliary rear heater unit. Rear heater unit consists of a heater core and 3-speed blower motor enclosed in a housing. Rear heater unit is mounted on floor, behind driver's seat. Rear heater unit recirculates air inside vehicle.
Auxiliary rear heater unit's coolant flow control valve is engaged after instrument panel's temperature control lever is moved past its first quarter of travel. Auxiliary rear heater blower speeds are controlled by a separate 4-position toggle switch mounted on instrument panel, below heater controls. (Схема №6)
