That's normal. I'm short on time right now, i'll reply later in more depth. I'm also researching a permanent, no shortcut A/C fix. I think it might work, I'll let you guys know if it does, but it'll probably be at least a few days or a week before I get it figured out.

 

just as a update. I think and hope that poss has figured out the long awaited fix for the a/c. Here is the thread https://www.rx7club.com/power-fc-forum-47/power-fc-c-fix-435420/
