No WiFi or Bluetooth

I am working on a MacBook Pro 15" Retina early 2013. There is no Wifi or Bluetooth.

  • The Wifi icon says "No Hardware Installed"
  • The Bluetooth Icon says "Not Available"

Troubleshooting already tried:

  • Tried new screen with new antenna cables
  • Tried a new airport card
  • Tried battery pull
  • I also have tried PRAM and SMC resets

I'm trying not to have to reinstall software and back up old software.

Does anyone have any ideas as to what else I can try?

Thank you for your time

Before you alter the systems drive how about creating a clean bootable USB thumb drive with the same or newer OS. Follow this guide: How to create a bootable macOS Sierra installer drive.

Once you boot up exit the installer and then see if WiFi works going into the preferences setting. Is that working? If not you have a problem within the logic board power services powering the Airport board. If the external drive works then you have a messed up OS install.
