if the heater does not blow out warm air change the setting.
heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
Isn't a heater supposed to blow warm air?
It could be that you need coolant or it's low.
Yes.
It could be the thermostat on the engine. If the engine does not warm up adequately the heater will never blow hot air.
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.
cool hello
Heater core may be plugged . Flush the cooling system, also check thermostat.
Check your anti-freeze levels
i can turn the blower speed on low and the air gets warm , but not hot . then i can turn it to high and it get even cooler Check your thermostat, it may be stuck.
if this system uses dex-cool flush the system
