What You Need To Know About Condensation Inside Your Vehicle

One thing that can be frustrating about winter driving is when condensation forms on the inside of your windshield. Sometimes it happens because the moist, hot air from your breath condenses when it reaches the cold temperature of the windshield. However, there are other causes for condensation on auto windows, and some of them could leave you stranded along the road with a broken down vehicle. Here's what you need to know.

Possible Causes of Condensation Inside Your Car

• Is the carpet or the upholstery wet? The excessive moisture inside your vehicle can cause condensation on the interior side of your windows. If it snows or rains regularly where you live, keep a few sticks of chalk or a container of silica desiccant in an inconspicuous place or under your seats. This will help to absorb the moisture before it condenses on your windshield.
• Is the air intake is set to recirculate? If it is, set it to fresh air instead. This will help remove the moisture from inside your car while you operate the heater, defroster or air conditioner. That way, this moisture won't remain inside the car overnight.
• Is your windshield cracked or leaking? Could water be getting in through a broken seal or cracked window? Wipe down the area around the windshield and windows. Wash your car, then check for drips or leaks around the seals and glass. Or, take your vehicle to an auto glass service to check for leaks for you.
• Is the cabin air filter clogged? A clogged cabin air filter can trap moisture in the vent and inside your car. Read the owner's manual to learn how to change the cabin air filter in your specific car.
• Do you smell a musty odor when your air conditioner runs? This may mean the condenser drain is blocked, which may be causing the excessive moisture inside your vehicle. A blocked drain may cause your vehicle to idle at lower RPMs, which could cause your vehicle to stall.  
• Is there a sweet syrupy odor? Does the condensation leave a slimy residue? This could mean your heater core is leaking. A mechanic will need to make repairs. Check your coolant levels before you drive to the auto shop. With a leak in your heater core, you could be at risk of overheating your engine.

Condensation on the interior side of your windshield can be dangerous when it forms while you are driving. Not only can it cause you to not be able to see, you could be at risk of breaking down. It's important to figure out what is causing the condensation so you can have repairs done as soon as possible. Talk to your local glass experts, such as A.O.K Auto Body & Glass, for more information.
