Answer:
I think the aircon does not do anything with the overheat. vehicles are designed to run normal weather aircon is turned on or off.
Check your engine's cooling system which comprised of raidiator, fan, fan motor relay switch and temperature switch.
When cooling is not doing the job, you will not noticed this when you are running on the highway because your speed relative to the air cools the radiator. during traffic, no air is flowing so engine gets hotter and hotter. If you'll turn on your aircon, the time your engine overheats becomes shorter because the engine has increased its load.
Kia's cooling system control is very simple. the circuit is composed of:
1. fuse
2. relay switch
3. temperature sensor switch
4. Fan motor
which means you'll only have to check 4 components.
When your aircon is on, radiator motor fan does not run continuously because it has a separate control.
The load attributed by the aircon will be sensed by the temperature control and thus run the radiator fan but not continuously.
Hope it helps
Low coolant?Cooling fan not working?Defective thermostat?Defective radiator cap?
Make sure the connector to the Coolant Sensor is not corroded. If so replace with a new connector

No.
The 2nd fan on this car is for extra cooling when the AC is turned on, if you turn on the AC both fans should run; the relay is the first place to look if that fan is not coming on.
I believe that the fan(s) come on automatically with the AC system. Someone else might be able to confirm that. If so, then I would guess that you need to find and replace the temp sensor/switch for the fans.
Yes, this is a normal operation for most newer cars, and is designed to help prevent windshield fogging when using the defrost function.
you need to check cooling fans with ac on
Yes, If vehicle overheats it may cause freon (refrigerant) to blow out
You can find a AC pressure switch wiring diagram, for your Kia Sedona, at your local Kia dealership. You can also find the diagram at most auto-parts stores.
