30 Amp Fuse in #17 postion on the instrument panel fuse box blows. Have replaced the wiper motor park, high low speed, and washer relays. Tried wiper motor replacement and fuse stills blows. Unhooked washer motor and fuse still blows. Unhooked multifunction switch and fuse stills blows. Disabled White and Black wire on the wiper motor connector but fuse still blows. Disabling dark green wire on the wiper motor connector causes fuse to stay good and the wipers to run on low and high but not on vairble speed. GEM appears to be good with no visible overload spots. Have searched for a dead short between fuse junction box and wiper motor. Also, have searched for dead short between large fuse box and wiper motor.

Ok, I'm gonna go out on a limb here & guess that you have a short!....
The bad thing here is that fuse feeds a lot of sources so it can be a PITA to track down... I'm not sure how you were checking the circuit but I'll make a suggestion that might help things out a bit.....
Get yourself a 12v test light and hook the clip to the pos term on the battery.....Touch the engine and a few other grounds to make sure it lights up. Now touch the load side of the #17 fuse holder and it should light up indicating a short to ground. Pull out each of the 3 relays one at time. If the light goes out then that is the circuit your short is on. Also disconnect that w/b wire going to the motor. If the light stays on with everything disconnected then the short is up stream of the relays & motor and is in the harness that feeds those circuits.
A quick test you could do would be to start wiggling & moving the harness as much as you can in the parts you can get to. If the light goes out or even flickers, you are in the right spot....
With harness problems, I usually just stand back and take a good look at the whole harness before I get too deep into it. Look for obvious signs of damage or fluid saturation.... If it's moved, twisted, pinched, rubbing or oil soak it would definitely be worth a quick look......
After that it really gets to be a PITA...................gawd I hate shorts............lmao
