I own a 2017 Ford Fiesta s and the other day my Bluetooth shut off completely. I did the usual sync reboot which didn't fix it so I ended up pulling the fuse and putting it back in which fixed my Bluetooth but it caused the battery light to come on. The next day I turned on my car and it didn't connect to my phone at all. I did the sync reboot and pulled the fuse again which didn't work and my battery light was still on. I went to AutoZone to test my battery and alternator but they were completely fine then the guy checked to see if it had any maintenance codes and there was nothing. Now when I try to press the media button it keeps sending me back to my radio and when I try to turn the Bluetooth on keeps saying that it's off. I tried rebooting, factory reset, Are there any solutions to fix my sync or any way I can make my battery light go away?

When you say "Pulled the Fuse" - you have several based around the Audio and Console. You have fuses in two spots - one inside, behind the Glove-box, with the other at the Engine bay Fuse Block.

You now show a "Battery" - you may have two types of symbols, one that looks like a cartoon battery...another is a schematical representation, and you will see both on startup.

If you had to have any type of Handicapped assist equipment installed or bought it used and have no idea what the History is - the below can help you.

The above is pretty much what you'd find in the PODS on the car.

If you have the UNIVERSAL symbol then that light represents a problem with communication from the SYNC unit needing a power feed from the Battery to keep itself alive and functioning. Since you did have Bluetooth at one time, now you don't - this may mean you need service or you just have to find the Fuse that controls the SYNC side of the Audio Interface Module.

The Body Control Module may also kick on the Battery light because a feeder or the Fuse to it's interface that lets SYNC display messages using the Main Console has blown - you seem to have Radio - just no Bluetooth so the APIM (Accessory Protocol Interface Module which looks for all the stuff still connected - just isn't seeing it.

You may need to find the fuses and check the Glove-box ones to see if they blew, or you'll have to take apart the Dash to locate the Bluetooth Module in the main Console Display - for it may have a two-piece bolted-together unit that may have shifted or blown a fuse - which may require replacement - it has a ribbon cable that can shear off if the console was struck of you've been in an accident.

When you replaced that Fuse, did you do the one in the Engine Bay or Behind the Glove-box?

SYNC and the Audio Interface needs power from a 20A fuse in the Engine Fuse Block to feed branches to the SYNC and Body Control Module - if it's what I think it is, you just need to replace a fuse from those feeders that you haven't found yet.
