If those quick checks were the problem, we promise, we won’t tell anyone. However, if you still haven’t found the answer to ‘why is my heater blowing cold air into my car,’ the next step is to lift the hood to remove any possible obstructions, like leaves and debris, that might be blocking the cold air intake system. Airflow backup could also be caused by a dirty, clogged cabin air filter. A high quality cabin filter keeps the air inside your vehicle clean, while also trapping dust and dirt before it enters your heater core and evaporator. Locate your air filter, and remove it for inspection. If the pleats are clogged with debris, it’s due for a change. As part of a maintenance routine, replace your cabin air filter every 20,000 miles or 12 months, whichever comes first.
Another easy solution to solving a car heater problem is topping off the coolant level. If the coolant level is low, not only will heat not reach your heater core, but the built-up heat not being transmitted properly by coolant could damage your engine. If your coolant level is low, top it off. Be aware, it is critical that you also check for signs of damaged hoses or loose connections that could be leaking.
Another common problem that causes a car heater to pump out cold air is if the control valves in the thermostat are stuck open or closed. A thermostat is a temperature regulator in the form of a valve, situated between the engine coolant outlet and the radiator inlet. If possible, fix the stuck valves, or follow these tips for a full thermostat replacement.
You may need to put more air in your tires when temperatures drop, but don’t get carried away. Inflate your tires to the manufacturer’s specifications to ensure good wear, proper traction and optimal tire safety.
