Jeep 2004 Liberty - Manual (Page 203)

Window Fogging
In mild but rainy or humid weather, windows will fog on
the inside. To rapidly clear the fog off all the windows,
select the defrost mode, turn the temperature control
knob fully clockwise, and position the blower control to
its highest speed. Once the windshield has been cleared,
adjust the controls for your comfort.
On air conditioned vehicles, the compressor will operate
when in the Mix or Defrost modes and when the outside
temperature is approximately 30°F (-1°C) to provide
additional defrost/defog.
Summer Operation
Air conditioned vehicles must be protected with a high
quality anti-freeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
REAR WINDOW FEATURES
Rear Window Wiper/Washer
A rotary ring switch on the control lever, located on the
right side of the steering column, controls operation of
the rear wiper/washer function. Rotating the center of
the switch up to the DEL (Delay) position or the ON
position will activate the wiper. Rotating the switch ring
beyond the ON or OFF position will activate the rear
washer. The wash pump will continue to operate as long
as the lever or ring is engaged. Upon release, the wipers
will cycle three times before returning to the set position.
