Apparently, many drivers instinctively turn off the air conditioning in their car when they want to defrost the windshield in wet conditions because they think the air conditioning is just cold air.
According to NAPA, that’s only half of its functionality.
When you think about the air conditioning, you should actually remember that it is dry air, the car experts explained.
When the air conditioning system is operating, the moisture contained in the air condenses in the evaporator because cold air cannot absorb as much moisture.
This is why a puddle of water supposedly collects under your car when you use the air conditioning on a humid day.
The evaporator in a car is located in front of the heater core in a vehicle’s airbox, which controls the temperature independently of the air conditioning system.
The pros say that hot, dry air blowing on your windshield clears fog much more effectively than hot, moist air.
Therefore, it is recommended to ignore the urge to turn off the air conditioner on a cold or rainy day.
Leaving it running will improve your visibility in wet weather, so you don’t have to resort to a rag to fog up your windshield.
This means you can keep your hands on the wheel and drive more safely.
If you’re trying to fog up your windshield, turn on the air conditioning — even on a cold day, experts recommend.
While it’s handy to clear your windshield when it’s raining and/or damp, there’s a problem with the air conditioning.
According to Auto Express, the refrigerant that cools the air can lose its effectiveness over time.
This can cause the system to pump condensation into the car and actually fog up the windows.
When this happens, experts say it’s time to refill the car’s air conditioning system.
This can be done as part of servicing a car by a dealer or a local mechanic.
