To Aid In Side Window Defogging/Demisting In Cold Weather Conditions - Ford 2003 Crown Victoria Owner's Manual

Climate Controls
compressor will operate automatically if the outside temperature is
above approximately 2°C (36°F). The air distributed through the floor
ducts will be slightly warmer than that sent to the windshield
defroster ducts and the side window demisters.
• Defrost - Distributes outside air through the windshield defroster
ducts and the side window demisters. The A/C compressor will
operate automatically if the outside temperature is above
approximately 2°C (36°F). This mode will clear ice and fog from the
windshield.
Operating tips
• To reduce fogging under humid weather conditions, place the climate
control system in Defrost and Rear Defrost (if equipped) mode before
driving.
• To reduce humidity buildup inside the vehicle: Do not drive with the
climate control system in Off mode. Do not drive with the climate
control system in Max A/C mode (if equipped).
• Under normal weather conditions, do not leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped) or Off mode
when turning off the ignition.
• Under snowy or dirty weather conditions, leave your vehicle in Max
A/C (if equipped), recirculation control (if equipped), or Off mode
when turning off the ignition.
• Remove any snow, ice or leaves from the exterior base of the
windshield.
• To increase the efficiency of the A/C (if equipped), drive with the
windows slightly open for 2–3 minutes or until the vehicle has been
"aired" out.
• Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.
