2011 V6 MCA Mustang Premium w/Shaker and SYNC -> AM/FM/Sirius, A/C, heater, fan controls, and the CD are all dead. The only thing I see on the display is AM 590, current clock time, SW for compass direction and 51 degrees outside temperature. There is loud static coming from the radio at all times. I’m unable to turn off or adjust the volume of the static it’s just loud all the time. There is no response from any of the controls on the front console. The engine starts and I can drive it just fine. All gauges in the dash are functioning correctly. Electric seats, locks, mirrors and trunk release all work fine. When I got in the car this morning the battery was fully drained and I had to jumpstart it from another car. Any clue as to why nearly everything in the front console is non-functional? Thanks

Yes, I’ve checked 8 fuses in the passenger fuse box and 8 fuses in the engine fuse box that I thought might have the slightest impact on the dead components. All were good. Still searching for the cause. The vehicle had been sitting in my garage unused for about a month before I found the battery completely drained. No modifications were made on the vehicle between the times they all functioned and then were discovered dead. I did notice one evening about a week before I had to jumpstart it as I was walking through the garage in the dark that the lights (only in that console) were on with no key in the ignition. I opened the driver’s door, closed it and those lights did go out as the rest of the interior lights went out. I never thought to go get the key and start it up right then. I suspect something in that console went south and drained the battery as it lost its life.

How old is the battery? The cars system is always putting a drain on the battery even when it is off to keep power to all the electronic devices.

I’m not sure about the age of the battery. It came with the car when I bought it a year ago. I don’t see any date codes on it anywhere. After I jumpstarted the car and let it run for 30 minutes it did recharge the battery. I was able to leave the car sit overnight and it cranked right up this morning so I assume the battery is OK.

Being you don't know it's age, probably best go and have it load tested.

There are a couple threads on this site regarding similar issues. There does appear to be some commonality with dead batteries. Some owners have experienced the CD changer motor constantly trying to eject / shuffle a CD, didn't notice the clicking sound, and this drew their battery down. Others have experienced Shaker unit problems after their battery died.

+1 for a battery load test.

You might also try just disconnecting the battery overnight to induce a computer reset (reboot). There are sporadic reports this has worked for some owners.

You might also visit your local MobileOne Audio or BestBuy. Any one of those store locations will have swapped out dozens of Mustang head units for better aftermarket ones. Go around the back and see if you can talk to a technician. He or she may have experience troubleshooting and/or cause(s) of failure. Worst case scenario is a unit replacement.

Good luck!

with the car running, weak battery should not be the issue

I'm thinking it has to be a fuse somewhere; because what else could all those things have in common? maybe an in-line fuse inside the dashboard somewhere?

EDIT/PS -- just noticed this was a dormant thread, wonder if the OP mayerm200 already figured it out, but hasn't been back

I did figure it out, apologies for not posting the solution here. Here it is.
After a lot of online searches I found a similar posting (can’t find it again though) by a Ford tech that authoritatively said disconnect the negative terminal of the battery for 15 minutes then reconnect it. Check to see if the problem has been resolved. If so, great. If not, and the lights on the buttons and dials are still illuminated, then you most definitely have a defective FCIM (Front Controls Interface Module). The FCIM is mounted directly onto the rear of the panel that holds all of the control buttons and dials for the Radio/CD Player, Heater and A/C. I found a used one on Ebay for $125. It came with the FCIM mounted on another whole panel with all the same control buttons and dials. It took about 45 minutes to remove the dead Panel/FCIM and install its replacement. It works great!

With the car running, a weak battery is still an issue, the car is running the alternator harder to try to keep a weak battery charging, this will shorten the life of the alternator.
