What makes the air warm in a car heater?
It is your car's cooling system that removes the excess heat from the engine. Then, by a convection process, transfers that heat to your heater core. The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hoses transfer engine coolant to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment air. The heat transferred lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again, a continuous system. Whereas the radiator is located at your car's front grill, the unit that transfers heat to the passenger cabin ( heater core) is located inside the dashboard. Heated liquid coolant circulates through tubes in the heater core, and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warmth through the heating vents into your car's passenger cabin.
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…
[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…
The heater in my 2000 eclipse rs doesn't work both of the pipes going into the heater core are hot any suggestions on what could be wrong?
I assume the blower motor is going. There might be an air bubble preventing the warm water from circulation through the heater core, you might have a build-up of sludge doing the same. Or maybe there's something broken in the valves in the air ducts preventing the heater from releasing warm air into the car.
Why do you smell exhaust fumes from the car in front of you when you turn on the air conditioner or heater in your 2003 explorer?
When you warm up your car in the driveway cold air enters the cab then as you start to drive down the road warm air enters cab?
If you changed the thermostat flushed the heater core and the hoses to the core get hot why would you only get warm air in a 95 Chrysler Concord?
On some cars there is a door that opens and lets cold air through the heater core thence giving warm to the interior of the car. Something in the operation of this door is apparently off. It could be as simple as an adjustment on the temp. control switch, but some doors are operated by air or electricity.
Possible causes; Low coolant, broken water pump, severely clogged cooling system. The heater uses the heat in the engine coolant circulating through the engine. It uses a heater core which is basically a smaller version of the car radiator. If there is no coolant flowing, the heater core will not be able to warm incoming air.
It could, but your car may have a second thermostat for the heater coil for the interior of the vehicle. A service manual for your model may be available at your local library, or auto parts store. Also a problem directly with the heater coil itself could cause it. If your car is not overheating, it probably is not the water pump.

Answer There could be several reasons why a car heater doesn't blow hot air and they are as follows. 1. The Thermostat is no longer functioning properly 2. Could be that the radiator is old and not enough anti freeze flows properly. 3. Water pump could be on the way out. 4. Maybe you are low on anti freeze 5. There is a thing called the heater core, if this heater core isn't working properly…
