I hope your not heading down the same track I was with my old bighorn.
Eventually got that down to the power feed to the relay which would come right every time I looked at it and work till the next time it was critical for it to work like when it started pouring with rain or a river crossing and the windows down or the engine is overheating on a big hill and the window is up.
Took 10 years to eventually track down

Re: all power windows not working (96 wizard)
on my 97 ucs69 wizard the windows relay is 2nd from bottom in a row of 4 behind drivers kick panel, a different layout from the previous document. I have removed my relay and put a link across the battery and output terminals marked 30 & 87. My windows now all work irrespective of key position.
I also noted the 87 terminal in the window relay block is loose and could well be the cause of window failure. It appears the relay hasn't been removed since manufacture.
