Convection
its called an immersion heater
The heater is like a small radiator(heater core) usually located in the dash. The fan blows air through it and heats the car. There are two heater hoses that carry coolant to & from the heater core.
it is essentially a tiny radiator. hot coolant goes in and heats up the fins in the heater core and your fan blows air through the heater core thus heating up the air and you.

Check your coolant level. It may be critically low.
its the energy source. Sun heats Earth, Earth heats air, air expands, air rises, new air blows in. Its called wind.
Check coolant level Perhaps thermostat is not opening to allow coolant to circulate through engine and heater core
A heater core in a vehicle takes some of the heat from the coolant and runs it through a heat exchanger. The blower in the car that blows hot air into your car runs through that heat exchanger which heats the air that enters your car.
the water is heated by the motor and goes into a set of coils inside a box near the firewall and a fan blows through the coils and it heats the air and is blown out the vents.

the wire that heats blows
