On Saturday morning I woke up and my MacBook wouldn’t turn on. I’ve tried smc and pram resets already but nothing seems to be working. The only cause I could think of is that I spilled a bit of water on the touch pad but it should have dried up by now. I’ll attach a picture under the cover of it. Please help.
Given where you spilled I suspect the Touchpad got wet and the corrosion maybe limited to it. Here’s the needed part MacBook Air 11" (Mid 2013-Early 2015) Trackpad and here’s the guide you’ll need to follow MacBook Air 11" Early 2015 Trackpad Replacement I would start there
