Jeep 2007 Wrangler - Manual (Page 256)

Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum fan and temperature settings for best windshield
and side window defrosting.
NOTE: The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes even if
the fan switch is not in the A/C position. This dehumidi-
fies the air to help dry the windshield. To improve fuel
economy, use these modes only when necessary.
Blower Control
Use this control to regulate
the amount of air forced
through the system in any
mode you select. The fan
speed increases as you move
the control to the right from
the OFF position.
