ADJUSTING CABIN TEMP WHEN RAINING
A car’s air conditioner (AC) is indeed useful during the day to keep the cabin cool, especially when the sun is bright, bringing the ambient temperature up.
But that’s not the only benefit of the AC. During rain, your AC can help prevent foggy windows.
While this function is certainly helpful to maintain the driver’s optimum visibility, you also need to be wise in setting the ideal temperature. Too cold will only make both passengers and drive uncomfortable.
So, what’s the recommended cabin temp? If your car comes equipped with a digital AC panel, you can easily check cabin temp by glancing at the panel and adjust from there. If the cold bothers you, bring up the temperature to 22, 23, 24, 25, or even 26 degree Celsius. If you have a conventional AC panel, then adjust the temp using the switch.
Also use the Defroster mode, if available, to clear fog from the windshield because air circulates via the AC ventilation directly to the front.
If the cold is a little bit too extreme for you, directing your AC vents, or turning off the AC completely, are not the solution. Foggy windows appear because of the difference in cabin temp and outside temp. As such, shifting your AC vents to the windows may cause your cabin to be colder inside than outside, while turning off AC causes the opposite to happen. Both, however, creates fog that can hamper driver’s visibility.
Let your AC works and try adjusting the temperature. Better yet always be prepared by dressing warm or have a jacket or sweater handy to keep you comfortable.
