Can I use the A/C system to defog my car?
by Jamie Ruf
One thing that tends to baffle drivers is how to go about defogging their car windows. They try the heat and have no success. They try the cool air and are not sure if they are having success or not. They may even see the air conditioner come on when they try to defog, only to have them often reach over and shut it back off. It can be a confusing situation, but luckily there is a solution!
Yes, you can, and probably should, use your air conditioning system in order to defog your car. Even if it is cooler outside and you don’t feel you need the air conditioner on. This is because the air conditioner will work to make the air dryer, which will lead to a removal of the fogging that is covering the window.
Drier air, caused by the air conditioning system being on, will clear your window faster and get you seeing better. Some vehicles are automatically set up to where when you try to defog the window the air conditioner comes on. This is because the drying effect that the air conditioner has will be more helpful than setting those temperatures on anything else.
Plus, using the air conditioner periodically in off seasons, or when it is not summer time, is good for the system. It will help prevent decomposition of the parts, which leads to leaks. So using it to clear the window is actually a win-win situation.
The next time your windows are fogged up, forget fiddling around with the heat and trying to figure out which temperature will help you clear it off. Just put the air conditioner on it and see how quickly you can see clearly again! Before you know it your car window will be defogged, your air conditioner will be exercised, and all will be right again!
