How to Fix Your Heat in Your Car

Winter is coming, and the last thing you want is to be driving around in your car without any heat. If you’re experiencing a lack of heat in your car, don’t worry, there are a few things you can do to fix the issue. Here’s how to fix your heat in your car:

Check Your Thermostat

The first thing you should check is your car’s thermostat. The thermostat regulates the temperature of the engine and the coolant that flows through the heater core. If the thermostat is stuck open, it will prevent the engine from reaching operating temperature, which means your heater won’t work. If the thermostat is stuck closed, the engine will overheat, which can cause serious damage.

Check Your Coolant Level

If your car’s coolant level is low, it can cause your heater to blow cold air. Check your coolant level and top it off if necessary. Be sure to use the correct type of coolant for your car.

Check Your Heater Core

If your thermostat and coolant levels are fine, but you’re still not getting any heat, it could be a problem with your heater core. The heater core is a small radiator located behind the dashboard that heats up the air that flows into your car. If the heater core is clogged or leaking, it can prevent the hot coolant from reaching it, which means your heater won’t work.

Check Your Blend Door

The blend door is a small flap that controls the flow of air through your car’s heating and air conditioning system. If the blend door is stuck or broken, it can prevent hot air from flowing into your car. Check to see if the blend door is working properly and replace it if necessary.

Check Your Heater Fan

If your heater fan isn’t working, you won’t get any heat. Check to see if the fan is running and replace it if necessary.

Check Your Heater Control Valve

The heater control valve controls the flow of hot coolant into your car’s heater core. If the valve is stuck or broken, it can prevent hot coolant from flowing into the heater core, which means you won’t get any heat. Check to see if the valve is working properly and replace it if necessary.

Check Your Radiator

If your radiator is clogged or damaged, it can prevent hot coolant from flowing through your car’s heating system. Check your radiator for any damage or clogs and replace it if necessary.

Check Your Hoses

If the hoses that carry hot coolant to your car’s heating system are damaged or clogged, it can prevent hot coolant from reaching your heater core. Check your hoses for any damage or clogs and replace them if necessary.

Check Your Water Pump

The water pump circulates coolant through your car’s engine and heating system. If the water pump is failing, it can prevent hot coolant from reaching your heater core. Check your water pump for any signs of failure and replace it if necessary.

Conclusion

If you’re experiencing a lack of heat in your car, it can be a frustrating problem. However, by following these simple steps, you can diagnose and fix the issue. If you’re not comfortable working on your car’s heating system, it’s always best to take it to a professional mechanic.
