What do you mean by it is stuck in auto mode? Does the display not respond to your inputs? Or do you really mean that there is no control of the airflow? direction? speed? temperature?
There are actuators that control where the air comes out and what temperature the air is. These can stick and fail. Have you made any attempt to test and diagnose the system? (Dealer level scan tools required.)
You can keep throwing parts at it, but it is often cheaper to diagnose instead.

Even in AUTO mode it should change with temperature settings. I keep mine the same all the time and have in temperatures from below 0 to over 100. So, are you saying it never adjust temperature or fan speed? At startup, fan should be high, but as it cools, will slow down. Does yours?

Given the parts already replaced, you may need a dealer diagnosis.

Well, there you have it. It’s dead, not stuck in the AUTO mode. The vehicle was built in 2008. It’s dealer service time.

I really think that you are at the point where paying to get it properly diagnosed is your best course of action now.

Well I have an appt on the 15th couldnt get anything sooner im just trying to brain storm whatever I can until that day comes, ? Would a failed climate control unit cause this or the in car temp sensor I read somewhere that there is a sensor to the left of the center speaker not sure. Thanks for all the help guys truly appreciate it immensely I need to get this done

Okay fellas sorry for the delay I have great news and information regarding this issue ive had for the last month so here we go
Took the genesis to the dealer on monday 349.00 for diagnosis and 4 mechanics scratching their heads lol bottom line I asked them and the service guy if this had a climate control module and the answer I got from all 5 people 4 techs and service guy was No its combined with the climate control unit now on here I found that it actually does have a seperate module so I get a call this morning and the service guys say hey guess what theres a module and its bad and I told him yea I knew that because my guys on Genesis Forum are awesome like that and thats what I learned from them. So bad climate control module just fof information purposes here the years and part number that will work for this issue.
Climate Control Module part#972553M500
2007-2014 all genesis use the same part certified guarantee. I want to thank all of you for your feedback and also for telling me to take it to get diangnosed got 3 recalls done a list of things that need to get done and also heating element inside the seat are shot found replacement seat for 191.00 dollars each in grade A condtion on partslocator.com all this for 5 days of diagnostics for $349.00 you definitely cant beat that I ordered the module for $65.00 dollars versus 1300.00 dealer lol.
