A car's heater works very much like the radiator at the front of the car, except there's a small radiator near the footwell. The warmth of the water running through the engine is radiated and a small fan blows the hot air throught the vent pipes and into the cabin and voila! Chances are the fan is not operable.
There is no heater blower is a Honda. The heat created on the air condition system is heated up through a heater core. If there is no heat coming out then the heater core will be the culprit.
check the thermostat dude may need replacing
If its the button below the heater dials then it is the air conditioning button. It's the only snow symbol in my 2002 Corsa.
The simple solution is to set your heater to recirculate so no new fresh air comes in. If it is coming in through the doors and such you may need to replace the seals.
The air coming from a car heater can typically reach temperatures between 120°F to 160°F (49°C to 71°C) or even higher, depending on the vehicle and the settings. This warm air is produced by circulating engine coolant through the heater core, which then warms the air blown into the cabin. The actual temperature can vary based on factors such as the outside temperature, the car's engine temperature, and the heater's settings.
Your heater core is leaking, Need to REPLACE HEATER CORE.
More than likely the heater core is leaking.
This happens because the heating wires heat up the air around them. This air is less denser than the surrounding, and so it rises up through the top of the heater. If the paper decorations are above the heater, they will definitely flutter because the air is coming through the top.
If a 2001 VW Beetle does not have hot air coming from the heater there is a problem with the vehicles heating system. The heater core is malfunctioning and will need to be replaced.
Check both the heater core as well as the heater hoses for leaks...........
If your Vauxhall Corsa's heater isn't blowing hot air, it could be due to several reasons. One common issue is low coolant levels, which can prevent the heating system from functioning properly. Another possibility is a malfunctioning thermostat that doesn't allow the engine to reach the required temperature. Additionally, a blocked heater core or a faulty blower motor could also be the culprit.
just had an rac bloke come check my car which was actually overheting,but also suffering from no hot air coming through the heater when switched to hot. he found it to be the thermostat.
