Answer:

The windows in my car get foggy too, sometimes. It depends a lot on the weather and also the people inside and whether the air conditioning/heater is running.

Car windows fog up when water condenses on them. This can happen both on the inside of the window and on the outside. You can check to see in your mom's car where the condensation is because it will be wet to the touch.

It sounds like outside humidity might be a problem (especially on the East coast). It is here in Illinois, particularly on hot, stormy days in the summer. Water will condense on a surface if the temperature of the surface is below the dew point of the air next to that surface. So you need warm, humid air next to a cooler surface to fog up.

If it is very humid outside and you're running the air conditioner inside the car, water can condense on the outside of the windows. Using the windshield wipers and the rear defroster can get rid of condensation there by wiping it off or making it evaporate.

Often, the air in the car will be warmer than the air outside the car (this happens in winter here). Moisture will condense on the inside of the windows if the outside air is cooler than the dew point inside the car. This happened to me a lot when driving through a thunderstorm caused by an incoming cold front. In this case, running both the air conditioner, the heater, and the vents for defrosting the front window worked very effectively. The air conditioner dehumidifies air because water condenses inside it when the air goes past the cold tubes with the refrigerant inside. Heating it up way past its dew point makes it feel dry, and it is dry -- it'll help evaporate any condensation that's on the windshield -- and even more quickly the hotter it is because heat is needed to cause the liquid water to change phase to a gas.
