Default electric problems.

Okay guys I'm having two problems with the truck. I've searched online for about a month trying to fix this problem. Hopefully y'all can help me out a bit.
04 f150 lariat 5.4:
1- When I turn off the truck and take the key out and open the door, my stereo is on and still playing music. I've sat in the truck with the key out and door open for about 10 minutes, figuring if it turns off. the stereo will play for about 8 minutes and then shut off. The stereo is a pioneer double din that I've had for about 4 months now.

2- When I used to open the doors to my truck, the interior lights would turn on. Now when I open them, nothing comes on unless I turn them on manually. I can't remember since when it started happening until a friend asked me why they didn't turn on.
If anyone on here nows about these problems or has had these problem, please help me out. I would greatly appreciate it.

It sounds like you either have a bad door switch, or some wiring issues connected to it.

Does the door switch apply to all four doors or just one?

The switch itself, no, at least I don't think so. If you have a scab, then there's one switch for each side. If you have an screw, then there's one switch for each door.
From your description, it sounds like the truck just doesn't know you opened the door, and the accessories delay is what is keeping the radio on. If you open the passenger door, will the radio stay on?
I've heard of the wiring under the door sill corroding and causing this issue too.

Doesn't matter which doors o open the accessories still stay on. The stereo and window switches all still work for about 15 minutes

It definitely is related to the truck not knowing the doors have been opened. Seems odd two switches would go bad at the same time, so it sounds like some kind of short or other wiring issue.

I forgot to mention it's a super crew. Could it have something to do with the fuses in the fuse box?

It could. Have you checked the fuse or the relay?
