fogging

Ah, fogging—the bane of any driver's visibility and a sneaky menace lurking in your car's cabin. It's usually caused by moisture condensing on the inside of your windows when the temperature difference between the inside and outside is just right to create a personal fog bank. Common culprits include:

• Leaky door seals or windows letting moisture in
• Blocked or malfunctioning air conditioning systems
• Wet carpets or upholstery

To combat this, crank up the AC or heater to dehumidify, or get those seals checked at ServiceCentral. If you're buying used, keep an eye out on Tradingpost or CarShowroom for complaints about persistent fogging—it could be a sign of bigger water ingress issues.
