When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later.

A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat.

Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates how the coolant flows through the engine. You may have a leak somewhere in your cooling system. Those leaks may be something as simple as a detached hose clamp or as serious as a bad head gasket. A knowledgeable technician at John's Automotive Care will be able to track the problems down.

For those reasons, it's wise to get your vehicle's heating system repaired. Not only can driving an unheated vehicle on a cold day freeze your fingers, some related engine problems that are not repaired could leave you stranded.

Smart drivers keep up the maintenance on their vehicle's cooling system; it's a hot tip to prevent a cold vehicle.
