I drive a 2013 Ford Taurus SEL 3.5L V6.
I recently ran into an issue where I got into my Taurus and started it....and my radio was not working.
It showed that I was connected to a channel (103.5 here in pittsburgh) but I could not get any sound.
I also tried using my Bluetooth Device but I still had no sound.
After reading a plethora of forums here online, many pointed to a new ACM
Though through troubleshooting a few things on my own - I seem to have fixed the issue.
1) I made sure my SYNC system was updated to the latest release (didn't fix)
2) I tried adjusting Sound settings (didn't fix)
3) I tried turning the car off an on multiple times. This did not fix the issue either.
I was able to fix the issue however by using a longshot tactic that I learned in electronics and my Network Communication classes.
While sitting in my car, I locked it fully (using my key-fob) until I heard the 'beep'. Then, I unlocked the car with my fob and started my car normally (push to start in this case) and my sound magically started working.
I have also found (because this happened more than once) that using my Remote Start also fixed the issue. Though this could point to needing a new ACM
in the future, it seems to work successfully for me right now.
There are many other tactics to remedying this issue. You can remove the battery for multiple hours to make sure it is completely drained and then try to reapply, you can attempt to reset a fuse (remove and reinsert) but it is recommended that these only be done if you are aware and familiar with what you are doing. If you are untrained, or are unsure of exactly what you are doing, it is always best to contact a Ford Support Team member before delving into deeper issues than you may already have.
I hope this post may be able to help somebody out there.
