Going nuts electrically...
My 2001 F250 with the 7.3 is having some issues with the windows, wipers, etc not functioning when I twist the key to ACC. If I start the truck, these items still will not operate for the first minute or two. Is this a faulty GEM? I have checked the Delay Relays and swapping them out does not help.
Thanks in advance.

Either you or a helper hold a finger on the delay relay while the key is turned to the ACC position. If the relay is energized with a delay it's probably the GEM. If the relay clicks right away then it's probably an issue with the circuit that passes through the relay contacts.

There is a relay on the gauge assembly that wears out. I am having the problem too. See here: https://circuitboardmedics.com/ford-...luster-repair/

My bad, I thought they were the same.
I did do some research. I am an electrical engineer and I wanted to find a way to do it myself. I could not find a direct fit relay or socket from the pictures I found, but I think you could easily solder on some leads and connect a generic SPST relay. Here is the note I made when I was researching it: https://www.ford-trucks.com/forums/1...l#post18231110

Nah, they did a semi-major change in the Super Duty electrical systems from the 99-01 vs. 02-04 models. The GEM went away in 02 and the functions it handled were moved elsewhere.
Just as a note, the relay in the cluster is not the "Accessory Delay" relay, it's the "Battery Saver" relay which controls the accessory delay relay which is still located in the CJB.
