ward from the instrument panel, injectors receive maximum hot air. During normal opera-
tion, the knob is set in OFF position.

Two knobs, located on the lower side of the central pedestal, allow Defrost and Cabin Heat
function. The one marked as ―Defrost and Cabin Heat‖ allows hot air to perform wind-

The cabin heat control knob, when fully outward, allows cabin to receive maximum hot air.
When both cabin heat and defrost and cabin heat are pulled, air is partitioned.
