If you’ve ever experienced a car without heat during the harsh winter months, you understand how uncomfortable it can make simple trips and commutes. From a faulty HVAC system in your vehicle to a lack of sufficient fluids, a car’s heater can shut down for a variety of reasons. Read through our list of potential reasons your heater might not be working, and contact us if you need assistance fixing your car’s icy performance.
1. FAULTY THERMOSTAT. A broken thermostat is a very common cause for vehicle heat issues. A thermostat that is stuck open or closed can not only cause issues with your heat but also your engine’s cooling system.
2. CHECK YOUR COOLANT. As counterintuitive as it may seem, your vehicle’s cooling system also works like a small radiator. When the engine achieves the right temperature, a mixture of coolant and water is formed that is passed to the heating core using hoses and valves. If there is not enough coolant, it can cause the heater not to work. Check your coolant levels to ensure there is a proper amount, and that rust particles or other contaminants are not in the coolant.
3. BROKEN HEATER CORE. A car heater core works similarly to a car’s radiator — it's consists of a series of narrow tubes and fins. These tubes are susceptible to clogging and leaks, which reduces the coolant level or flow through your engine’s cooling system. The result? A heater that does not blow hot air. Brrr!
1. DON’T WARM UP THE CAR. Many have heard that in the winter, it’s important to let your car warm up for some time before driving. This is actually not true! At most, your car should not idle for more than 30 seconds at a time. According to both the EPA and Energy.gov, this is a huge waste of money and energy. Instead, turn on your ignition without starting the engine, which allows your fuel pump to prime the engine to produce heat.
2. PREVENTIVE MAINTENANCE IS KEY. Never underestimate the importance of preventive maintenance, especially when preparing your car for winter!
