E72E Error after HVAC panel Swap

I recently swapped out my LCI HVAC panel for another LCI with seat heater buttons. Everything works fine except for the AC. The button lights up but I can tell the compressor isn't turning on and I receive no cold air. I have an error code E72E. Do I need to code this new panel? Anyone been through this before?

Ok so I found this shortly after I made this thread.

In here he claims his fix was to reset his IHKA module to factory settings. I will try this and see what happens.

Yep that fixed it, just reset the climate control module to factory settings and now my AC works.
