Kia Troubleshooting Questions? Ask a Mechanic
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
You need to scan the hvac module for codes. This will tell you if you have a sensor issue. You will also need a set of ac gauges to see the pressures of the system. Pressures will tell you a lot about how the system is working. Is the larger line leading to the evap cold under the hood near the firewall?
I can send you the repair procedure if you like.
If you accept the offer I will be able to send, thanks.
