Kia Troubleshooting Questions? Ask a Mechanic
Hello, my name is***** the compressor for the AC is not turning on then the issue is typically in the evaporator temperature sensor. This is assuming that the system is full of refrigerant. I have replaced these on this vehicle more than anything else. It is typically checked with a scan tool that will read the sensor data. It can also be the controller or another sensor but this is by far the most common. I hope this helps. Please let me know if you need further assistance.
