Ok so this is the weirdest thing i have dealt with on this truck or any truck. 2008 f150 xlt for reference.

When the truck is on and driver door is open or closed the radio does not come on. If i turn truck off (keys out of ignition) and open door, radio comes on. Now it gets weirder:

If i open and shut the rear driver side door, radio comes on but only if the truck is on. If truck is off, the radio will shut off with both doors open.

I've searched for this issue and it seems as if the purple spliced wire on driver rear sill is to blame, but that seemed to be all ok, no corrosion, cuts, etc. Next is to check the radio fuse but alas work lunch is only an hour.....
Any others have this issue or thoughts to fix it?

That's most likely the delayed accessory power fuse, or one of the switches at the door. But it's most likely delayed accessory power.

Delayed accessory fuse looked ok. darn, was hoping that was it. That would have been an easy fix lol. hunt continues, thanks though.

Figured I'd update this in case someone experiences my same problem and searches for some answers. I checked all radio associated fuses, sprayed wd-40 into door jam, and the wiring underneath the driver side rear sill plate and all looked good. Still was having issues.

Started messing with it again one evening and just sort of fidgeted/squeezed with the black rubber piece that funnels the wires through the door (see picture) and it all started working fine from then on. Been 2 weeks and zero issues. Stupid weird i know... So i suspect its a corroded or nicked wire somewhere in there. Not gonna open that can o worms until it starts messing up again.
