SW1 L4-1.9L SOHC VIN 8 (1996)
When Vent mode is selected, air enters the module. After flowing through the evaporator the air passes through the mode valve and out through the
instrument panel outlets. The air maybe warmed by directing some or all to pass through the heater core by adjusting the temperature lever to the
desired heat level.
HEATER MODE
When Heater mode is selected, with Recirc OFF, outside air enters the module and passes through the evaporator core. With A/C button OFF the air is
no cooler or drier than when it entered.
When the temperature lever is moved from cold to hot, the temperature valve directs some or all of the air from the evaporator through the heater core,
warming the air passing through it.
The mode valve closes and directs most of the warmed air to the lower and rear air outlets. A small amount of bleed air exits through the defroster
ducts.
IMPORTANT: During extremely cold weather, -2O°F (-29°C) or colder, the engine's coolant temperature will decrease quickly when idling with the
heater fan on high speed and cool air may flow from the heater outlets. The fan control switch should be set at a slower speed position (fan speed I or
II) to maintain the hottest air flow.
DEFROST MODE
