Winter weather can be tough on your car, but you can easily escape the cold this year by keeping your car’s heating system running up to its full potential. Your heating and cooling system directly affects how easily your cabin warms up and also helps keep your windows clear of frost with your defroster. If you have noticed any decrease in your heating system’s ability to get up to temperature on cold days, now is the time to go through this checklist of potential problems. If you need any parts or tips for this or any other DIY project, come into your local U Pull And Pay today. Our expert staff will help you get everything you need to quickly and efficiently take care of any DIY project you want to tackle this year.

Refill Your Antifreeze

Antifreeze is extremely important for your car to function to its full potential this winter. Coolant is comprised of 50% antifreeze and 50% water and functions to transfer heat away from your engine block while it is hot and distribute that heat along common fluid lines. Having low antifreeze is one of the most common solutions for a malfunctioning heating system. Make sure that you check your coolant reservoir first and refill as necessary.

Check Your Thermostat

Your engine thermostat manages the rate at which your engine heats up. The heat created from your engine is then transferred across many other heating systems of your car. If your engine thermostat is not allowing your engine to heat up all the way, your internal heating will take much longer to kick in or may never turn on at all. If your heater isn’t working or taking a much longer time than normal to kick in, your engine thermostat could be the issue.

Test Your Blend Door

Your heater control air blend door controls the airflow to your cabin, allowing you to choose the exact temperature that is perfect for you. The door itself is controlled by a series of electronics including cables and vacuum seals, which all can malfunction. You can check your blend door by moving the heat from hot to cold while listening for the movement of the door itself. If you don’t hear any movement, you need to replace your blend door.

Purge The Heater Core

Occasionally air bubbles can get stuck in your heater core, causing it to stop working entirely or drastically lose strength. You can get rid of these air bubbles easily by turning on your car and letting your engine get fully up to temperature. Once it is up to temperature, jack up the front of your car and let it run for two minutes. After two minutes lower the front end and lift up the backend for two minutes as well. By doing this you will essentially “burp” or purge your heater core.

Check Vacuum Lines

A broken vacuum line can cause your whole system to stop functioning. If you hear a hissing noise behind your dashboard while the engine is running, chances are high that you have a broken vacuum line. If the breaks are small you can use adhesive to repair the line, but you will have to replace the whole line if it is severely damaged.
