Default Strange electrical issues

Good evening ladies and gentlemen I have a problem with my 2006 H3. The battery died the other morning and I charged it cleaned all the terminals and put it all back together. The truck starts fine and runs fine. The HVAC lights do not light such as AC recirculation and rear defrost. The stereo also does not have power. I checked all the fuses I could think of according to the diagram, but had no success. I reset the computer by leaving the terminals off for an additional hour and put them on positive first then negative the problem still exist. I am open to any advice at this point as I said everything runs and drives fine. The fan control works. The dash position works as well. I don’t know how to check the recycle switch and my AC has never worked again. If I push the rear defrost, I get no light please help thank you.
