What Can Cause My Car's Heater to Stop Working

You get into your car on a cold morning only to find that your heater is blowing cold air - you wait for your car to "warm-up" yet nothing happens. Is your heater broken, and is it a serious issue? 

Your vehicle's heating system is actually complex and is directly integrated into your vehicle's cooling system. The warmth that your vehicle uses to warm the air before it is released into the cabin is actually from the heat of your vehicle's engine, transferred through coolant and the heater core. 

A problem with your vehicle's heater core or low coolant can actually cause issues with your air getting warm when you turn on the heater. So while you may think a broken heater isn't necessarily a big deal, the truth is that you may have a cooling system problem.

Low coolant or a bad heater core can cause some serious issues when it comes to your vehicle's engine. If heat isn't being rerouted from the engine, your engine can quickly overheat which can cause engine damage. This engine damage can be costly to repair, so if your car heater isn't working, it's important to have your vehicle inspected as soon as possible. 

The issue could also be with your vehicle's thermostat, which is another key component of the cooling system. If the thermostat isn't reading the right temperature, the coolant can stay hot and overheat the engine.
