I have a 2004 new model f-150. The radio stays on until the computer shuts it down after 15 min. I've check the door switch. And it's good. Anyone know why or how to fix this problem?

 

Try to restart first

 

Are you saying that it does NOT shut off after you open the drivers side door? If you just shut off the key and it doesn't shut off, it's normal. Will continue to be powered until the timer shuts it off...- OR you open the drivers door.

 

Interesting, my brother's 04 F-150 does the same thing, and it does NOT shut off after the doors are opened/closed, stays on for 15-20 minutes.
