Sounds like your fan control on setting is set to low.
How to fix heater in Buick there is cool air ,fan is work .but no warm air
heater core may be partially plugged up or the heater hose may be collapsed so that in motion the cold air can contribute to cooling the small amount of coolant reaching the heater but at a motionless idle the warm engine compartment helps keep the heater producing warmth
Your heater may be blowing cool air instead of warm air due to issues such as a malfunctioning thermostat, a clogged air filter, low levels of refrigerant, or a problem with the heating element. It is recommended to have a professional HVAC technician inspect and repair the heater to resolve the issue.
Humidifiers do not warm or cool the air in the home. They simply add moisture to the air to increase humidity levels. If you're looking to warm or cool the air, you'd need a separate heating or cooling system like a heater or air conditioner.
The heater core could be burnt out. Make sure your antifreeze is full and your switches on the dash are working. When you move the switch from cool to warm you should be able to hear a difference. If you don't the door/flap may not be moving.
if the heater does not blow out warm air change the setting.
When a warm object and a cool object come into contact, heat transfers from the warm object to the cool object until they reach thermal equilibrium. This means their temperatures will eventually equalize, becoming an average temperature between the two initial temperatures.
cool hello
usually that the heater is swithed on. However if the setting sais it is not set to heat the cable that is conected to the settins may have come loose.
With the engine warmed up and running, open the hood, locate both heater hoses (supply and return), feel each heater hose with your hand. If one hose is hot and the other is only warm or cool, you have a plugged heater core. If both hoses are only warm or cool, you have a faulty thermostat. If both hoses are hot, you have a temperature blend door problem (possibly a faulty actuator).
heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
The cool air sinks, while the warm air rises. If it does so with enough force and torque, a tornado or hurricane will form.
