How do I adjust the settings on the air conditioning?
Experienced mechanics share their insights in answering this question :
You want to travel in comfort at just the right temperature. Adjusting the temperature and fan allows you to find the ideal environment for all of your journeys.

Turn the dial that controls the fan speed clockwise to increase it or counterclockwise to decrease the speed of the fan.
Turn the dial off if you don’t want the fan running at all.
Turn the temperature control dial in a clockwise direction for a warmer setting or counterclockwise for a cool setting.
To cool out the car quickly, switch the temperature control dial to Max A/C.

You can change where the air comes out by pressing the buttons that direct the air to the feet, feet and air vents, just the air vents or the feet and defrost.

A very common cause of an air conditioner not being cold is that the refrigerant needs to be recharged. You can charge it yourself with a charger kit, but you may be more comfortable bringing it to the shop for an easy fix. You can recognize this symptom if you can feel cold air but it is not actually blowing.
Meaning, the refrigerant used has escaped and there is not sufficient refrigerant to pressurize the system properly, resulting in hot air. When this happens, the system must be checked for leaks, the leaks repaired, and the system recharged. 2) A problem mechanically or electrically with the under hood components.
If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
Set A/C to the coldest setting

Your car`s air conditioning is most efficient when set to the lowest temperature and adjusting the fan for comfort. Most air conditioning systems cool the air to 3-4 C. A higher temperature forces the system to re-heat the air, burning more fuel.

The Automatic Climate Control is one of the most advanced features in the vehicle for passengers` comfort. It manages the cabin temperature and humidity levels. You have to set the cabin temperature, and then the system controls the temperature, which does not depend on the outside temperature.
One of the most common reasons your car AC is blowing hot air is because of a refrigerant issue—specifically, a loss of refrigerant. This loss of refrigerant can occur either due to a leak or because your car`s refrigerant levels are too low.
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

the most relevant questions and answers related to your specific issue

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

Air conditioning is blowing hot air – car stalls when A/C is on
ANSWER : In order to diagnose all the different problems you have, I having the A/C pressures checked to see if the system is low on refrigerant from a leaking compressor or another component. The rough idle may be due to a dirty throttle body and idle control system. If you would like to have this checked for you, a certified professional from YourMechanic can come to your car’s location to inspect the A/C and rough idle in order to proceed with the proper repairs.

Air conditioning blowing mildly cold air on the coldest setting, turned off/on again, now blowing cold air, should it be checked?
ANSWER : If you are getting ready for a long trip and suspect the cooling fan may be not coming on for the radiator and a/c then you should have the a/c and cooling system performanced checked before trip. Nothing worse than breaking down when out of town in a strange area.

My 2003 Hyundai air conditioning works fine but often starts blowing hot air, especially when idling.
ANSWER : Hi There,
It sounds like you may have a condenser fan that may not be cooling the AC condenser properly. As you may know, the job of the AC condenser fan is to cool down the AC condenser as it generates a lot of heat during the course of its primary function, which is to convert the AC gas refrigerant into a liquid form, a process that generates a significant amount of heat. As the AC condenser fan blows cool air across the condenser, this allows the condenser to remain cool, keeping the pressure down in the AC system which helps to generate cooler air. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.

Ac compressor clutch isn’t engaging on high fan speed setting while it engages on the prior three fan speeds which are all slow.
ANSWER : The blower not working is most likely due to a fault with the blower resistor. When you go to high blower speeds the A/C may disengage the compressor if the cycling switch cycles or the high pressure switch gets over pressurized, shutting the compressor off. The first thing to do is to get the blower working correctly then test the A/C pressures using A/C gauges. If you’d like to get this fixed, consider YourMechanic, as a certified technician can diagnose your A/C issue and fix it accordingly. Good luck.

air conditioner not blowing air from dash vents, but blowing air from side vents
ANSWER : A few different items can cause the air to not blow out of the dash vents. The most common are a blend door or a control switch. The best method for the AC diagnosis feature can be found in the vehicles owners manual. I recommend having your AC checked by a qualified technician, such as one from YourMechanic, to have the problem diagnosed and repaired correctly.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.
