Battery dead after watching DVD on rear system

[ninjafied]

After watching a movie in the rear of my truck my battery is dead in the morning. If I pull the #3 fuse from the interior fuse box it kills the system and saves my battery. I obviously don't want to do this every time. So I'm wondering where the problem might be. Is the interior fuse box supposed to have power all the time or just when the key is on? Also the DVD player will try to continuously eject and load. I'm getting ready for a long trip and would like the system working for my kids. Any advice will be appreciated.

Thanks

Always nice to know what year we are talking about

I don't believe there should be power to the DVD without the key. Also if it's loading and unloading continually, there is a problem with the player.

Ya sorry the trucks a 2007 limited max

Pulling Fuse #3 is useless as Fuse #3 should only have power when the key is in the START or RUN position

And if Fuse #3 is powered with the key out then you have a problem elsewhere

yes fuse 3 does have power so now where does that come from some relay perhaps?

Will look at the prints and see what they show
