Steps
Start the engine and switch on the climate control system. On most 2011 to 2023 Chrysler 300 models, the controls sit on the center stack or in the Uconnect touchscreen.
Press the front defrost button. Look for a windshield icon with wavy arrows. This sends airflow to the windshield and usually switches on the air conditioning.
Set the fan speed to medium or high. More airflow clears fog faster, but full speed can be noisy.
Set the temperature to a warm setting. Warm air holds more moisture and helps clear fog and light frost from the glass.
Turn off recirculation so fresh outside air enters the cabin. Recirculation traps moist air inside and makes fogging worse.
Press the rear defogger button, shown as a rectangle with wavy lines. This heats the grid in the rear glass; on some trims it also turns on the heated mirrors.
Aim the side vents toward the front side windows if they are fogged. Adjust the vents by hand and do not block them with papers or phone mounts.
Wait until the windshield, rear glass and mirrors are clear before driving. Then press the defrost buttons again and return to your normal climate settings.
Tips and common mistakes
Never pour hot water on a frozen windshield; the sudden temperature change can crack the glass.
Do not scrape the rear window grid with a hard tool; use a soft brush or let the defogger do the work.
Using the A/C in rainy weather helps dry the cabin air, even when you also use warm air.
Leave the rear defogger on only until the glass clears; many cars switch it off automatically after a set time.
Questions
Why is my Chrysler 300 windshield still foggy after I press defrost?
Check that recirculation is off, the A/C is on and the fan is above low. Fog can also stay if the cabin is damp, so wipe up wet mats and let fresh air in.
Does the rear defrost button turn on the heated mirrors?
On many Chrysler 300 trims it does, but it depends on the model year and trim. If your car has heated mirrors, watch for the mirror icon or check the owner's manual.
Where is the front defrost button on a Chrysler 300?
It is on the climate control panel or in the Uconnect touchscreen, depending on the model year and trim. Look for the windshield symbol with wavy arrows.
