Operation CHARM: Car repair manuals for everyone.

Air Delivery

The air delivery system has five modes: Vent, Bi-Lev, Heat, H/Def. and Defrost. You select each position by pushing a switch button on the heater control panel. In addition to the five modes, you can shut off the air or change the source of the air (fresh or recirculated) by using the RECIRCULATE/FRESH switch.
