Trunk Won't Open SOS

2018 Mazda CX-9 GT
Hey guys I had a cooler full of melted ice and on the way home it flipped and spilled and a lot of water got into the trunk area yesterday. Fast forward to today, and well now my trunk won't open. It won't open with the keys, or the front trunk button, nor the button directly on the trunk.

Any help or suggestions would be appreciated.

At this point im hoping it will dry out and be fine but part of me thinks ill have to bring it to the dealer and they will charge me a lot to fix it :X

Look in the index in your owner's manual for Liftgate > When Liftgate cannot be opened. In my 2016 manual it's section 7-50.

When you get it open, dry everything and take a good look. If it's completely dry and still won't operate, check the fuse box near the driver's left leg. In my '16 it's manual page 6-60, fuse #5 PLG, 20 amp.
