There’s nothing worse than turning on the heater during a cold Kelowna morning and getting blasted with cold air instead. If your heater isn’t warming up as it should, it’s usually a sign that something isn’t working correctly under the hood. At Paragon Motors in Kelowna, BC, we hear this complaint a lot, especially in fall and winter. The good news is that most heater issues are common and fixable once you know what’s causing them.
Low Coolant Is a Common Culprit
One of the most common reasons a heater blows cold air is a low coolant level. Your vehicle’s heater uses heat from the engine coolant to warm the air before it enters the cabin. If the coolant level is low or there’s a leak in the system, there won’t be enough heat to warm the air. You might notice the engine temperature gauge acting strangely or see warning lights come on. Low coolant doesn’t just affect cabin heat. It can also lead to engine overheating if left unchecked.
Problems With the Thermostat or Heater Core
A stuck thermostat can also cause cold air to blow from the heater. If the thermostat stays open, the engine may never warm up enough to produce hot air. On the other hand, a clogged or failing heater core can prevent heat from reaching the cabin. Signs of heater core trouble can include weak heat, foggy windows, or a sweet smell inside the car. These issues usually get worse over time, so it’s best to catch them early.
Airflow and Control Issues
Sometimes the issue isn’t heat, but airflow direction. Modern vehicles rely on blend doors, actuators, and controls to direct warm air into the cabin. If one of these components fails, the heater may blow cold air even when the engine is warm. A faulty blower motor or clogged cabin air filter can also reduce airflow, making it feel like the heater isn’t working correctly. Since many of these parts are hidden behind the dashboard, proper diagnosis is key.
