Failed trackpad and keyboard
Hi there!
Working with a MacBook Air 13" Mid 2012. Trackpad and keyboard failure arose after minor water damage (water likely entered from ventilation holes as keyboard was covered with silicon protector): everything except the power button malfunctioned.
Replaced the upper case cable and the problem was resolved until a week later, when the same failure recurred.
Any diagnosis and recommended repairs welcomed. Thanks!

Update: I've replaced the upper case cable a second time to verify that I've not received a faulty cable. This time, the repair did not resolve the problem, even temporarily.

Update: For no apparent reason, the trackpad and keyboard became functional again. I was in the middle of browsing a website on my bluetooth keyboard and trackpad when they suddenly became unresponsive and the built-in hardware kicked back into life. Very confused. Would appreciate additional diagnosis based on this development as I anticipate the hardware to fail again in the near future.
