the reason that the heat would cease to work when the car overheats is that the car is low on coolant. coolant is warmed by the engine as it transfers heat away from the engine. the heated coolant passes through heater hose and through the heater core. The blower motor blows air through the heater core warming the air and pushes the warm air through the vents in the car to you. the heater core is a small radiator in the dashboard of most vehicles. If there isn't coolant in the car, the engine becomes too hot thus the overheating. a side effect of this is that the lack of coolant means that coolant cannot get to the heater core to be warmed to warm you
because when you drive theair is pushing on your car and goes inside the car and goes warm and heats up as you go
put on ac in car and over heats
clogged radiator
If you run your car with the emergency brake on it will heat the car up.
the way the heat enter a car is sort of like a green house. when sunlight is traveling through glass some of the sun heat enter and some reflect back. the heats bulits up and heats up your car. If your car was black or a dark color it will obsorb the sun heat so if you were to touch the car it will most likely burn your finger. the heat will come out of your car if you were to open it.
if it has a plastic impeller inside water pump it may be broke or faulty thermostat .check by boiling in water till temp its suppose to open
Take the thermostat out, start the car and let it idle, see if it over heats. With the thermostat out of your car, it should just constantly circulate water, making it take longer to heat up. If it heats up fast then chances are that your pump is out. DO NOT LET THE CAR REDLINE.
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 friction between the tire & the surface your driving on causes heat and which heats the tire + the air...
Either the thermostat is stuck in an almost closed position and there is not enough flow of coolant through the engine block or you have a lazy water pump over time the impeller of the water pump wears out causing low coolant flow, so when the car is moving the water pump spins faster letting enough flow through the block.
