D5 AC suddenly stopped working after unflagging battery and dash control

First, sorry for typos in title, I can edit it for some reason....

Last night I disconnected my battery’s in trunk.

I then took apart the from dash and radio reference a squeak. I fixed that.

Put everything back together, now my AC doesn’t work ( blows hot air only)

Doesn’t sound like the ac is kicking on at all.

Tried already the following:
Passenger footwell fuses. Didn’t see one blown but I could have been looking at the wrong ones. I don’t know if there are any other places with fuses that control AC system.

Now since i disconnected batter, do I need to do a reset? I made sure everything thing is re connected back to control panels three times.

What are 'dash controls'?
Did you replace any modules?
Double check your connections?

I took dash apart to fix an annoying squeak. The control panel that has all the controls for heat, AC radio controls volume. I check and triple checked.

Possibly I’ll look at it, I don’t know if I’ll be able to tell visually if it’s super sensitive. Thanks for all the reapnses so far. I just swore it was gonna be a fuse that was blown because I connected my battery to run the fans ( I was sweating my ARSE off doing this), while I was finishing plugging the controls back in (two wiring harnesses one the back.) since the batter was connected thought maybe the connection of the wiring harnesses shocked the fuses and blew. But I guess not. Maybe burnt the relay or something?

You connected the battery while you had connectors disconnected? That is not good. You may need a scanner to read and clear hidden codes. You try disconnecting the battery for a bit and reconnect?
