[Heidi]

The reasons for the Kia K3 air conditioning not cooling are as follows: 1. The air conditioning switch is not turned on: The air conditioning switch is the A/C button, and some new car owners might easily make this mistake. 2. The air vents are closed or the airflow direction is incorrect: First, ensure that the air vents are open and not blocked by any objects. Additionally, it's important to understand how to adjust the airflow direction of the vents. 3. Using the external circulation mode in hot weather: Using the external circulation mode in such conditions will draw hot air from outside into the car, naturally reducing the cooling effect of the air conditioning. Therefore, during hot weather, it's advisable to use the internal circulation mode unless there's a specific need for external circulation. 4. Turning on the air conditioning when the car interior is very hot: Especially for vehicles that have been parked under the scorching sun for a long time, remember to open the windows first to let the hot air out before turning on the air conditioning.
