Default P1807-00 Four-wheel drive high ratio - short circuit to ground

Hopefully somebody can point me in the right direction. Literally down to 3 codes now. Driver seat heater, cruise control, and this.

I looked at the wiring diagram and tested pin 20 on the switch which reads 12 volts (14+ when running). Not sure what other leads I should be testing.

I have read some other posts where it ended up being the switch. Is there a process to test this outside of switching it with another?

I grabbed another switch piece as the shifter portion had a bunch of broken clips so will swap to see. never know.


Any help appreciated.
