Went to unlock doors of truck and when I did it tripped command center fold down motor. Motor constantly runs when driving. Eject button won't close it back up. Still semi works can turn on or off but won't close up. Putting in DVDs/CDs doesn't close it either. Tried holding many of the buttons down to no avail. Don't understand it. Really annoying while driving. Included image of what it looks like and you can imagine the lowering motor just constantly buzzing. Any help would be much appreciated.

 

Is that a standard MB head unit? Mine is different to that and doesn't fold down.
