Trying to find out what the "relay control center" controls on the vehicle listed above Ram Van 2500. I'm having issues suddenly with no turn signals (but hazards work), the radio won't turn on, and the windows won't move all at once. I'm thinking it's a relay as those are mostly different fuses. (Other thoughts are appreciated).

An interior electrical schematic of the radio and windows would help to see where there are cross overs between the elements.

I found the exterior electrical diagram someone kindly posted dealing with turn signals.

I attached 4 pics of the power distribution from the interior fuse box. Nothing that I see crosses. So I started looking through grounds. Again, nothing crosses. However, I did want to note that the grounds for these components are all located on the left side of the dash. Check to see if you can locate anything that looks damaged, loose, or corroded as far as a ground.

Let me know what you find.

Thank you for the information. I'll go hunting for loose or damaged wires and see what I can find. I'll let you know what it turns out to be.

Haven't hunted the issue down yet. However, it was pointed out that the items are all on the same circuit in the first wiring diagram (with the three red circled areas). However, I can't see what the lead is above the fuse block on the top is to check that. By any chance does the image go just a little further up or have a continuation? If it does, would you be so kind to share?

Thank you for your help.

Not a problem. I attached four pics below. It is the entire page the previous pic came from. I had to break it into 4 parts for you to be able to read it. I did overlap and indicate with letters which one comes next. Additionally, I placed them in order below.

Let me know if this is what you needed or if it is something other.

Take care,
Joe

Turns out it was the ignition switch in the steering column. There was one prong on it that was discolored and not healthy. Turns out that one nodule controls all the accessories that went kaput. (Found a cheap, used service manual for that helped us pinpoint the electrical issue). Thankfully, replacing the ignition switch solved the issue and everything is now fully working.
