How to Prevent Your Car from Fogging Up

As the seasons get colder and the days get shorter, driving can become even more of a challenge. Once autumn arrives, the carefree days of easy summer driving and fun road tips start to recede in the rear view mirror. Instead of having endless hours of sunshine and late sunsets, we start seeing earlier arrivals of darkness. Before you head out on a trip during the winter time, it’s a good idea to carefully check what the weather conditions will be along your planned route. With winter, you can also experience conditions that are unique to those months.

Your vehicle may start fogging up on the inside. This can happen because the air that is inside your car or truck is typically more humid and warmer than the air outside of the vehicle. If there is a significant temperature difference, you may find that moisture forms inside of your car and the windows take on a foggy appearance. Fogging up can occur quickly at times, so you need to know what you can do to clear the fog so you can drive safely again. Your Belmore mechanic can give you additional tips on how best to tackle winter driving challenges.

Keep Your Inside Glass Clean

We are all used to cleaning the outside of our windshield when we stop at the service station. It’s also important to keep the glass inside of your car or truck clean. Over time, the inner glass in your vehicle can get a slight oily haze because of contaminants in the air from the vinyl, plastic and other material in the car.

Your glass will de-fog much more quickly if it is clean, because it’s harder for the water vapour to attach to a perfectly clean surface.

Manually Set Your Vehicle HVAC

Basically, your fogged-up window surfaces are caused when the extra moisture in the inside air condenses on glass that is colder than the surrounding interior air. You can set your vehicles HVAC system to help clear the fog. If you run into any issues with your HVAC, consult with your Belmore mechanic.

If you turn on your vehicle’s air conditioning, it will help lower the level of moisture inside. You should set the system to bring in some outside air, rather than on recirculate. Finally,  turn the temperature on the HVAC to hot and the fan to high to get rid of the remaining moisture in the air.

Using the Climate Control System

If your vehicle has one of the more advanced HVAC setups, you will simply be able to active that automatic defog / demist function.

This system will set up the HVAC to perform optimum defogging, all with the simple touch of a button.
