Just an update here. I found some suggestions to pull the touchscreen fuse from the fuse box and then re-insert it. I did that as it is way easier to gain access to than the 12v. That actually seemed to reset the system and turn the AC off. When I turned the car on the AC started back up but when I locked it the AC shut off as it would normally do. Still no touch screen functionality but at least the AC won’t be running non stop. Hopefully can get it to the SC tomorrow if they are open (doubtful) but at least by Tuesday to get this MCU upgraded. Thanks
