I need to add some info and a possible conclusion that even I think is out there.
While scanning deeper into the codes on my vehicle I picked up a generic code U1000 that I saw somewhere means a bad or corroded connection somewhere, and knowing my luck, it is somewhere in the harness.
Also while checking for trouble codes associated with the transmission it shows an issue with the back up lights and even stranger that the transmission is staying in 3rd. no matter the position of the shifter or the dash indicator, which is working correctly.
The other electrical issues I have are getting power to the fuel pump, scanner shows the fuel pump relay is on while cranking and off in the run position ( currently to get the thing to run I have to use a jumper ), rear hatch lock, air bag codes # B0026 driver front deployment open and B0044 driver front deployment loop 2 open.
I'm starting to wonder if these, instead of being completely separate problems may be connected as with broken or abraded wiring at a hidden pinch point?
Where I'm going with this is, does anyone know of a fairly common but hidden spot where pinched wiring or corrosion may exist and or is it even possible that one of the modules not correctly reading the transmission shift position may be blocking the transfer case from shifting?
