Why Isn’t Your Car’s Defrost Working Properly?
When cold weather hits, your car’s defrost system becomes your best friend.

It clears fog or frost from your windshield, keeping your view clear and your drive safe. The defrost works by directing warm, dry air onto the glass to remove moisture buildup. But what happens when it stops working?
If your defrost isn’t doing its job, there could be several reasons. A common issue is a clogged cabin air filter, which restricts airflow. Problems with the blower motor or a stuck vent door can also prevent warm air from reaching the windshield. In some cases, low coolant levels or a failing thermostat can keep the air from getting hot enough to clear the glass.
