You could have a problem with your thermostat in the car.
A leaking heater core will cause the engine to overheat because the coolant is leaking out.
The battery runs a fan that pushes air through the residual engine heat in the heater radiator into the car.
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".
the heater core is leaking
You may smell coolant when the ac is running but a leak in the heater core won't cause the ac not to work.
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.
Not very well.
have you checked the fuses? if so, maybe the heater core needs replacing
engine thermostat, fan motor,or fuse.
It could be steam from the heater core
You might need a new thermostat or heater core.
Possibly the Heater Motor, if the fan is not coming on at all the bearing in the motor have probably gone out.
low water, bad thermostat, vacuum door not working, clogged up heater core, heater valve broken........
The engine has to be running and warmed up for the heater to produce hot air. So yes, you need gasoline to get heat from your car (unless you have an electric car).
Maybe it is out of antifreeze? If older car, maybe you need the radiator and heater flushed.
[first time answering questions] car heater works like the reverse of the normal cooling radiator - in fact the heater is like a small version of the rad that's on the frnt of the car - the hot water from the engine block goes into this small rad and the heater fan blows air thru it into the car - the hot heater rad loses heat into the car and - bingo - you get warm inside
Yes. The coolant carries the engine heat to the heater core. Without coolant the heater core does not get warm.
No it wont. The heater core is just a small radiator inside the cabin that when the fan is turned on heats the air. A bad heater core will cause you to have no heat inside or will leak coolant on the carpet.
