Electrical Gremlins??? Help

OK, in my dads 99 dually, we have come across a few problems with what seems to be electrical issues. We lost the power 4x4 switch function, as well as wipers and washer fluid. We put up the following codes
C1728
P1820
P1828
P1866
P1867
B1456
B1438
B1350
B1352

Now here is the funny thing. When we hold the lock button down, all these electrical functions work. We couldn't get a scan of the truck either without holding down the lock button. Is there a gem module or some kind of relay or fuse we need to know about here? Any help is appreciated.

yep sounds like the GEM module is trash now. It is under the drivers side dass attached to the back of the Fuse block. Not to bad of an install but that module is expensive

Is there any way to diagnose this, as the part is like $500 up here? Just need to be sure as electrical parts are not returnable. Thanks

Find one in a junk yard up there, or one of us down here can help you find one. I paid $150 for my last one that I needed.

Hey Clay. Thanks for the offer. I would love to have you guys throw out the feelers for this part. Much appreciated. The part number for this gem module that is in his truck right now is:
F81B-14B205-EP

Thanks again fellas. The old man is retired and on a fixed income.
