Need help with electrical issue. Hopefully fuse blown?

Hi thanks for any help in advance.
I was working on center console, removing some debris and cleaning.
I removed headunit, unplugged the wire and plug that connects to the control block (the one with heated and cooling seat buttons), and then noticed the fabric that covers the wires were somewhat torn. So I decided to heat shrink tube the wires which I did, but during the process, I had to remove the 3 wires from the plug, because it was too big for heat shrink tube to fit through.
The 3 wires were female pins and when I removed them from the plug, I accidentally touched 2 of the wires with each other, creating spark.
Now the entire control block (heated cooling seats, rear blinds etc. Doesn't light up, nor works.
The AC control block that is below also stopped lighting up and doesn't work.
Did I blow simple fuse? If so, which fuse do I need to replace? I saw a list of fuse location information online but nothing shows any description of AC control block or switch block fuse.

Oh and by the way, how do I become a sponsor here?

By the way, the AC fan is blowing VERY loud under the hood.
sounds like I have AC on, but I'm not getting any air blowing inside.
The control for ac, as mentioned above, is dead, so I can't do anything about it.
Should I unplug the AC fan from under the hood? Will this cause issue?

The headunit works, as I can control navi, radio and audio..

Check fuse #12 in the engine compartment fuse panel "N10-1" which is near the driver's side firewall.
