iSight cable for mid 2009 macbook pro 13" help If my iSight camera no longer works and neither does my bluetooth, should my wifi still technically be working? Aren't they all co-dependent(if that makes sense) or can the fact that my wifi is still functional mean that the iSight camera still works and it's a software problem.
As you can see in step 20 of the take apart guide from iFixit, the camera cable and wireless card are one and the same cable.

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.
