Ventilation System - Chevrolet 1999 Monte Carlo Owner's Manual

Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Don't put decals there because you might have to
scrape them off.

Ventilation System

Adjust the direction of airflow by moving the vents.
-
Your vehicle's flow through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
Ventilation Tips
D
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle.
D
Keep the hood and front air inlet free of ice, snow or
any other obstruction, such as leaves. The heater and
defroster will work far better, reducing the chance of
fogging the inside of your windows.
D
When you enter a vehicle in cold weather, set the
mode to FLOOR and the fan to the highest speed for
a few moments before driving off. This helps clear
the intake ducts of snow and moisture and reduces
the chance of fogging the inside of your windows.
D
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.
