Nancy: In this frigid temperature, is your heat keeping you warm enough in your vehicle? Is it blowing cold air instead of nice warm air? Hi, I am Nancy at Kneble’s Auto Service Center and this is Stephanie.
Stephanie: There could be many different reasons for your heat not working in your vehicle such as 1. Low on coolant
Nancy: 2. Clogged heater core since coolant goes from the engine to the heater core that blows hot air. Your heater core is like a radiator and has the job of making the defroster and heat work.
Stephanie 3. Controls knobs or buttons could be broken and not able to turn on your heat
Nancy: 4. Thermostat not working because the thermostat’s job is to control the engine’s running temperature so the coolant can travel to the heater core. A thermostat stuck open will cause the engine to run cold causing no heat.
Stephanie: and #5. Possible coolant leaking from hoses, radiator or water pump which can affect your heat from not working
Nancy: So next time you turn your controls to heat and it doesn’t work, have it diagnosed so you stay warm in your vehicle.
Stephanie: Thank you for watching and like us on Facebook and share the information with others because no one should be cold while driving in their vehicle.
