As the coolant in your vehicle warms with the operating temperature of the engine, it can provide heat to the cabin. When you turn on your heat, coolant is circulated into a smaller radiator called a heater core. Your vehicle’s blower moves air over this and into the cabin. In this regard the heat of your vehicle is tied to your cooling system. Should your coolant level drop low due to a leak, or the thermostat of the engine stick or fail you may experience overheating issues as well as a loss of cabin heat. Your blower motor and/or door actuators may also wear out over time and use, causing a loss of air flow or inability to regulate the cabin temperature as you normally would. Whatever air flow quirks you’re experiencing, Phil’s can help you make it right.
