have you checked the fuses? if so, maybe the heater core needs replacing
Blown fuse.
you could have an air pocket in your core. the speakers check fuse.
A leaking heater core will cause the engine to overheat because the coolant is leaking out.
You have to take off the glove compartment, and some other paneling to get to a little motor with a whole bunch of gears right behind your center console. Just put grease (or Vaseline) on all of those gears, and you should be good to go!
If the drain plug under the evaporator coil is plugged up it will cause condensation to leak into the car. If the heater core is bad it will allow coolant to leak into the car. If the leak is warm and smells sweet it is the heater coil.
You could have a problem with your thermostat in the car.
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".
Not very well.
You might need a new thermostat or heater core.
I would check the coolant level first. When the coolant drops below a certain point,Warm coolant that makes the heater work is no longer present and all you get is cold air. If this doesn't work, I'd try a "hotter" thermostat.
No
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
There is only one thing you can do if your Heater in your car is not working. You will have to take it to the dealership and have them look at it.
low on coolent
