heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
Yes.
why does ac blow warm air? why does ac blow warm air?
if the heater does not blow out warm air change the setting.
It could be the thermostat on the engine. If the engine does not warm up adequately the heater will never blow hot air.
A bad alternator will cause a battery to go bad. It does not have an effect on the air conditioner.
The rear air conditioner of a Sienna will begin to blow warm air if the vent is incorrectly set. This will cause warm air to enter the vents rather than air conditioned air.
the sun cause un= heating of the earth making warm air to rise and cold air to sink. now you have wind.
You're probably out of frion, my friend.
If you mean how an air conditioner that goes in a window will blow warm air outside then that is because an air conditioner basically takes in air from outside and pulls out the cold air which then blows into your house then the warm air is released back outside.
I think it will last longer in a warm air because we blow balloons and we have warm air so I think is the warm air.
It could be that you need coolant or it's low.
