Why 2014 Volkswagen Passat Heater Not Working

Bad Thermostat

The thermostat is a valve that controls the flow of coolant through the engine. If the thermostat is stuck closed, it will prevent coolant from flowing through the heater core, which will cause the heater to not work.

Low Coolant Level

If the coolant level is too low, it will not be able to circulate through the engine and heater core properly, which will also cause the heater to not work.

Clogged Heater Core

The heater core is a radiator that is located in the passenger compartment. If the heater core becomes clogged with debris, it will restrict the flow of coolant through the core, which will cause the heater to not work.

Faulty Blend Door Actuator

The blend door actuator is a motor that controls the position of the blend door, which directs air from the heater core to the passenger compartment. If the blend door actuator is faulty, it will not be able to properly direct air to the passenger compartment, which will cause the heater to not work.

Faulty Heater Control Panel

The heater control panel is a switch that controls the temperature of the air that is directed to the passenger compartment. If the heater control panel is faulty, it will not be able to properly control the temperature of the air, which will cause the heater to not work.
