Getting the clutch cover off the display assembly is a bit tricky even for trained technicians and the cable routing is something you will want to be nimble and intentional when removing the connectors from the logic board and especially when repairing parts in the display.

I would say you could rule out software quite easily without taking your Mac apart by just installing a clean OS onto an external drive or USB storage device (be patient if your USB is slow). You could also reseat the cables on the logic board and inspect for damage there without too much harm of breaking things further if you are properly grounded when you open the Mac.

I believe bluetooth is controlled by the airport card and shares the airport antenna, but don't have access to definitive hardware manuals to know for sure. It's hard to guess if your issue is hardware or software just from the symptom.
