Dealing with Foggy Windows?

Winter driving in the mountains demands your full attention. One common problem is foggy windows and worse yet, a foggy windshield that impairs visibility. So how does this happen and how do you fix it?

On a cold day, any moisture in the air inside your car- from passengers breathing, snow on your boots, etc.- turns to condensation when it hits air next to a window that's below a certain temperature. The condensation is what makes your car's windows foggy.

To Prevent This:

1. Turn on your heat.

2. Turn OFF your air recirculation. When on, it continues to recirculate the humidity inside your car instead of bringing in fresh, drier air.

3. Turn ON your Air Conditioning. Yes, it sounds counterintuitive but AC is a dehumidifier and you can still run your heat with AC on. Remember, the goal is to remove humidity to prevent condensation.
