Non-Nav A/C controls not working PLEASE HELP!!!! (4 Viewers)

[Germ]

I went to go pick up a pop-up camper last night. Stopped and eat supper on the way home turned it off and everything. It was good until I got home turn the GX off. Went back outside to back the camper into the carport. Noticed then I have no a/c and there is nothing on the control screen and the buttons do nothing. I have a 05 non nav GX470. I've checked all the fuses and changed a couple relays just to see if it would fix anything and I still have the problem.
