Defrost air louvers
Use the support louvers and rear deck louvers to defrost
the windows and windshield. Direct the air flow for de-
frosting.
Turn the blower fan to the highest speed and close all
other louvers to direct maximum air flow on the windows.
If a fogging condition occurs, make sure that the recircu-
lation air louvers are CLOSED. If equipped with air con-
ditioning, turn the air conditioning ON, and turn the heat
control completely clockwise.
