After a failed attempt by my son, to install an overhead map light, in which he did not disconnect the battery, I found I had no power to my windows, sun roof, cargo light. Also, the 4wd high and 4wd low dash lights are blinking 6x every minute or so. I've seemed to have lost my passing gear as well. All issues with the possible exception of the passing gear, were working prior to the map light install. I've checked all the fuses inside the cab and under the hood. I've replaced all related relays in cab and under hood, (I still can't locate the relay block under the battery)with no fix. I've been led to the Generic Electronic Module as a possible solution but I can't get a solid yea or nay, since this module apparently also controls windshield wipers as well as other operations that work fine.
I'm still searching the archives here for an answer but haven't yet found one that fits well enough to explore. Could the 4wd and power windows be separate issues that failed at the same time by coincidence?

 

What model year is your Explorer?

That would probably help.
2000 XLT V6 4.0 I believe SOHC.

 

There are two items that appear to be related to everything listed (with the exception of the "passing gear" as I'm not sure what is meant by that) - The Battery Saver Relay and Fuse 26 (10A) in the Central Junction Box. I would certainly confirm those two items are fine before considering the GEM. I don't see any way that the PCM could effect the issues you listed.

As for "passing gear" do you mean Overdrive? Normally when you aggressively accelerate the transmission would drop out of Overdrive and possibly drop to a lower gear, maybe two gears lower, depending on the load and demand for power, so there's really not a "passing gear."
