Bluetooth not available, even after replacing Airport card

I had this issue where my bluetooth would sometimes just disconnect, so I figured the solution might be to replace the airport card. I did this and it worked fine for a little bit, but now the problem is back. There’s some software fixes I tried, like deleting the Bluetooth.plist files and resetting the NVRAM, basically anything I could find on Apple’s forums and on here. Is there anything else I should look into fixing?

Answer this question I have this problem too

Is this a good question?

Messing with the software won’t fix this! Hopefully you can undo the alterations.

To fix this properly you’ll need to replace the MacBook Pro 13" Retina (Late 2012-Early 2013) I/O Board Data Cable you may still need a new I/O board if it is corroded from a liquid spill.

Alright, thanks for the suggestion. I'll try it out and accept the answer if it solved the issue! And don't worry, I didn't make any drastic changes software-wise, just reset a few things that can easily be reverted.

Quick question, I found this guide MacBook Pro 13" Retina Display Late 2012 I/O Board Replacement. From the pictures, it seems like the data cable is accessible without removing the heatsink assembly. Is this correct? That would make the operation a bit easier. EDIT: Never mind, found the repair guide for the data cable only MacBook Pro 13" Retina Display Late 2012 I/O Board Data Cable Replacement
