That's odd. Every time my car goes in to my dealer, they run a query on the computer based on the VIN. It prints out any outstanding service actions and they add them on to the list of things to do automatically.

Maybe try contacting Kia's corporate headquarters and tell them that the dealer is refusing to apply a service action to your vehicle. I think Kia corporate wants everything kept up to date.

I'm trying that again before going back to the dealer but they are slow to respond and generally dismissive.

There is a diagnostic system for reading HVAC trouble codes from the console unit. Press the MODE switch more then 4 times within 2 seconds while pressing the OFF switch. The Kia Soul EV error codes are here - Kia Soul: Heater & A/C Control Unit (FATC) Repair procedures
The codes for using Torque Pro can be found by clicking the link in the website icon under my user name on the left.

Ok thanks for tip,
Checked and the same like with odb2 it is 00 so no alerts. But checked one more time heating and it's working in night when it is less than 30deg ;)
But about cooling could be no refrigerant in system and no alerts ?

If you are low on refrigerant then cooling hisses and gurgles a lot and it still uses power.

If it is too low on coolant it won't start the compressor (which does save power), but it doesn't throw any error codes then either, for some reason. I had this happen on my car last year. Once they refilled the coolant it was fine, but is running low again. Wish they could have found the leak but I get the sense they didn't look very hard.

My leak was the expansion valve on the back of the engine compartment, square thing with a round cap that the lines connect to. It was noticeably dirtier than the rest of the engine compartment.
