During the winter, the cold walks to the car from the grocery store or even your garage can be challenging. With each step, you're looking forward to the shelter of your car and the warmth of its heating system. That's why it's crucial to be on the lookout for signs the heater needs professional auto repairs. Here are a few of the most common red flags to watch out for.

What Signals That a Car's Heater Needs Auto Repair?

1. Foggy Windows

In addition to keeping you warm, your car's heating system is responsible for powering the defroster. When it's not working correctly, moisture can form on your windshield, windows, and back glass. This occurs when warm coolant gas leaks into the vehicle's interior. As it makes contact with the cold air in your car, it turns into steam. Then, it will condense on the inside of the windows.

2. Cold Air

Another sign of a faulty heater is a car's sudden inability to get warm. If you switch the settings from cooling to heating, but no hot air is coming out of the vents, there may be a hole in the heater core. As a result, all the warmth leaks out of the system before it gets through the vents. Small punctures may cause the air to feel lukewarm, while larger leaks might produce cool air.

3. Sweet Scents

You can also identify heater problems by using your sense of smell. A coolant has a sweet odor, so if you notice a maple syrup or candy-like scent in or around your vehicle, the substance is probably leaking out in a liquid form. You might see this fluid in a puddle underneath your car. It can come in various colors, from bright green to orange and pink. As it gets older, it may turn brown.
