The heating system doesn't get heat until the car warms up and the thermostat opens.
Low coolant, failed thermostat, partially plugged heater core...............
most likely it's a bad thermostat, or your vents not working properly.
When a vehicle is idling, the engine may not produce enough heat to warm the coolant effectively, leading to cold air from the heater. In contrast, while driving, the engine works harder and generates more heat, allowing the heater to blow warm air. The engine temperature can rise while idling due to reduced airflow through the radiator and less coolant circulation, while driving increases airflow and coolant flow, helping to cool the engine.
It doesn't really blow it out it just warms the cold air.
Your heater will blow cold air only.
The front expansion valve is clogged.
it wont blow heat itll blow cold air
you are low on coolingliquid !
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
Could be a number of reasons for this condition. I would check the coolant level. A low coolant level could cause your heater to blow cold air when the engine is warm. Is the engine warm? If the engine is fluctuating temp it could be a faulty thermostat. Hope this helps.
The heater may blow cold air instead of warm air due to issues such as low coolant levels, a malfunctioning thermostat, a clogged heater core, or a faulty blend door. These problems can prevent the heater from properly warming the air before it is blown into the car.
