Sorry for reviving an old thread, but I’m having the same problem with my 2014 13.3” 2014 i5. I did spill liquids in the trackpad, but I don’t think any got into the keyboard (all keys seems to work fine), but I can’t say for sure. Fan is running at full speed and the performance is quite poor. I disconnected the keyboard, keyboard backlight and trackpad ribbon cables, without any change to neither the fan speed nor the performance. I would believe if the trackpad and/or keyboard was faulty, disconnecting it would temporary correct the issues? I also disconnected everything to eliminate other hardware (IO board, speakers, webcam, etc, all connectors). I ran it on only the charger (with mag-safe board connected and battery disconnected), then disconnected the mag-safe board and ran it from battery only. No change. I tried both SMC and PRAM reset, fresh installed Catalina. Nothing helps.

Any tips? I’ve also inspected the logic board under the microscope and can’t see anyt damage. Could the liquid damage to the trackpad fry something on the logic board? And where do I start to trace the error?
