F350- Fuse/Relay problem

I have a 2003 F350 Crew cab diesel, 21K miles.

Power windows and radio are not working. Fine on one day, not working the next day.
Checked radio fuse, it's good. No power in Fuse Panel where 30a circuit breaker for windows clips in.
Noticed two 'fuse' panels under the hood, removed the covers, looks like relays, not sure what I'm looking at, each one is about one inch square.
Can someone offer a suggestion, what do these control?
What I should do next?

Thank you--

Thanks, it's a 2003, don't think warranty still is in force. Appreciate the reply. Like your truck.

Yep your right! Darn it eh! You could try to trace the powerwire that is dead to the fuse panel and see if you can find the reason for no power.

It looks like the only thing in common with the radio and the windows is the Accessory Delay Relay (relay K126 under steering wheel).

I would try swapping it out and seeing if the relay is bad.

Start with all connections... start from the source to the unit(s).. look for chaffing, loose wires, shorts, pulled apart connections... etc..

Like mentioned above.. major PITA..

Mine did the same thing yesterday, it was fuse #41, the one for the instrument cluster. By the way, the original post is two years old, I wonder if he ever figured it out?

I examined the FSM electrical diagrams and I could find no link between the radio and the windows, even though fuse 41 fixed it. I did a search and found this happens a LOT. Most times it is NOT a fuse. I have yet to find a post where, when it wasn't a fuse, it was easily resolved.

One guy said the dealer put in a whole new central junction box. Others have said they could temporarily fix it by smacking the dash just above the radio.

Whatever the issue is, it seems to have to do with the accessory shutoff delay.

Let us know what you find. Did you already check all your fuses?
