If you've ever stepped into your car on a chilly morning and turned on the heat only to find that your heater is just blowing cool air, you're not alone. While it may take seconds or minutes for your car to heat up, it's not common for it to stay cool your entire drive. Sitting in a freezing car is not very comfortable. Several common issues usually lead to the circulation of cool air from one's car heater:
- There isn't enough coolant in the engine
- There is an issue with your heater core
- Your thermostats are malfunctioning
- Your heating controls are broken
If you know and understand how the heating system in your vehicle works and the problems that can go wrong, it will make your time at Premier Automotive Service a little easier.
- There isn't enough coolant in the engine - Your vehicle relies on antifreeze/coolant for its HVAC system. This solution helps to cool the engine down while it is hard at work. However, when you switch on your heat, the coolant gets transferred from the engine to the heater core, allowing warm air to blow into the cabin. If your coolant levels are low, you will not be able to get warm air.
- There is an issue with your heater core - Heater core problems are often the culprit of a malfunctioning heater. Several things can go wrong with the heater core: coolant not traveling through it correctly, the blower motor air not reaching the heater core, or a potential clog or jam within it. It is vital to repair these issues immediately as the damage can affect your engine.
- Malfunctioning thermostat - If you see your temperature gauge on your dash reading "C," it may mean your thermostat is not working correctly. The thermostat must accurately show the engine temperature for the heating system to engage.
- Your heating controls are broken - On older vehicles, the heating buttons and controls can get stuck or broken. As a result, it can lead to disconnect within the car's computing system and HVAC system.
