There are few experiences as frustrating as driving down the road on a cold winter day and realizing your heater has stopped working, especially if you remember that the lack of heat could signal a major mechanical problem in your car.
Here are some strategies to try in this situation, recommended by approved auto repair specialists Jeffrey Boone and Ed Kriston of the Towson office of AAA Mid-Atlantic, headquartered in Wilmington, Del.
» Do put maximum defrost, vent or air recirculation on if the heater fan stops. That will still give you air flow that can help keep you warm.
» Do flip the fan lever. If the heat stops working when the fan is on the highest setting, switch it down to lower settings. Conversely, if the fan stops working while the lever is on a low setting, move it to a higher one.
» Don’t drive with fogged windows. Turn your fan to bi-level recirculation and crack the back windows open. This will improve air flow and clear the windows. You can also crack the sunroof for a similar effect.
» Do pull over if cold air blows out of the heater vents. That could mean the antifreeze is empty. Driving without antifreeze can destroy your car in minutes.
» Do not check the coolant when the engine is warm. Removing a hot radiator cap can propel antifreeze into your eyes and face, causing third-degree burns. Allow the car to cool before checking. Then carefully remove the cap, keeping your face clear of the area.
