Top Causes of Nonworking Car Heaters

  1. coolant leak car
    Coolant Issues - Low coolant levels or a leak in the system can prevent the heater from working properly. If the coolant can't reach the heater core, the air won't get heated.
  2. broken car thermostat
    Broken Thermostat - The thermostat regulates the amount of coolant that goes into the heater core. If it's broken, it might block the flow entirely, resulting in no heat.
  3. heater core failure
    Heater Core Failure - The heater core is like a small radiator that heats up the air. If it fails, it can't heat the air, leading to a cold car interior.
