Why does your heater in your car only heat when you are driving?

The heater in your car uses waste heat from the engine to heat the car. When the engine is not running there is no heat to distribute.

Car heater blows cold air when not driving?
A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.
Why does your heater only work when car is moving 00 Toyota Celica?
the heater of your car does not only work when the car is in motion. it only works when the engine is started. you don't have a heater in your car like you do your home. the heat that you feel when you turn on your heater in your car is produced by the engine. and there for if your car is not on then you will not receive any heat. some cars take longer than others to "heat up".
What makes the heat only work when car is in motion?
The heater is probably worked by the heat generated by the engine.
What is wrong when you can only smell gas fumes when the car heater is on?
what are you driving? email me direct if you wish
What can cause a heater to stop blowing heat?
well you could just turn the heater off heater blower ---- If it is a car heater then check your coolant level. the heater is driven off a heat converter that is fed by the radiator system. When the coolant fails to pump round the radiator system the car internal heater doesn't work. Driving without coolant in the system will result in the engine overheating and seizing.
Why would a car leak antifreeze only when the heat is on inside the car but doesn't leak when the heat isn't on?
The heater in a car is a little radiator under the dashboard. It's called the heater core. There's a valve in the water system that sends hot coolant into the heater core when you turn on the heat, and keeps the coolant in the engine when you don't want heat. If the car is leaking antifreeze when the heat is on but not when it's off, something in the heater system has a hole in it. Because there's always coolant in the heater core and the hoses that feed it, my first thought is the valve itself is bad.
What does the car heater core do?
heat It transfers engine heat from the coolant to the air inside the car.
Why will a car not blow hot air when sitting still only when driving?
On some cars this is because of the heater circuit design, in that if there is air in the cooling system it can gather in the heater core when at idle, and allow substantially less, if any, heat exchange. When the engine RPM goes up, as when driving, the air gets forced out of the heater core by the fast moving coolant and you have heat again. If this is your problem the solution is to bleed the cooling system on that vehicle, per manufacturer's instructions.
Why does your heat in your car only blow on high?
Because the resistor between the heater swithch and the heater motor is not functioning. Usually mounted on, in or near the heater enclosure. Its a common repair, and can be done by the do-it-yourselfer.
Why would a car only blow cold air when driving?
Only blows cold air with the a/c on while driving, your cooling fan or fan clutch is bad depending on the year, make and model.......... Only blows cold air with the heater on while driving, you will have a bad or broken internal a/c - heater control door.....
What does a heater core do?
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.
Why does car heater work when car is off?
The battery runs a fan that pushes air through the residual engine heat in the heater radiator into the car.
