How Do You Know if the Vehicle’s Heater Should Be Serviced?
As with your AC, it’s not always obvious that there is an issue with the vehicle’s heating system unless it fails to blow any hot air and is clearly malfunctioning. There can be smaller signs of growing trouble that you should keep in mind. For example:
* Antifreeze has leaked inside the car, on the passenger side
* Whenever you drive even for a few minutes, the windows and windshield start fogging up
* A strange smell is coming out of the air vents
