Water Sensors Near/Under Trackpad?

[HappyDude20]

My trackpad has been messing up lately, as in its not responsive all of the time as it once was. (13in mbp)

I have the applecare shipping box ready but am curious as to where the water sensors are located nearest to the trackpad to determine if any water damage has occurred.

I have no clue as to whether any liquid may have accidentally gotten in there, but nevertheless would love to check or something.

The water sensors are within the case and are placed around the trackpad and keyboard area. Getting to them is a complete pain and nearly impossible to get too without significant expertise (Its basically a total disassembly to get to them). ifixit may be able to help, check for a diassembly guide.
