The air conditioning in your vehicle may have a couple of different problems such as :
(1). your heater core may be out -- this can cost you because it usually takes time to get to the heater core. However if you have the time and patience to do you can save the money by doing it yourself.
(2). no refrigerant -- you will have to check your vehicles manual for the type of refrigerant to use
changes the air temperature inside
Automotive air conditioning is the ac unit in your car. It's what "conditions" the air in your car, ie keeping the temperature inside the car cool or warm.
because you need to keep warm when it is winter and other times when it it cold
By turning on the air conditioning. Or opening a window. Or parking in the shade.
The chemical in the air conditioning unit needs replaced.
The steam could be coolant from a bad heater core.
A.C. circulates air(just like a fan) and turns it cool.
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
The 1939 Packard was the first car with a true air-conditioning system.
It is broken. AC's usually blow cold air.
check cooling fan
Yes you can, just adjust the temperature settings all the way to the hot position and leave the a/c in the on mode..........
