So here's what I know (and it's not very much):
When switching to 4WD Hi, the light comes on steady, doesn't flash but does for 4WD Low.
When switching to 4WD, there is a pump on the driver's side by the degas bottle that runs continuously for a minute or 2 then shuts off. Does the same every time you cycle the ESOF switch.
There is a distinct sliding/clunk sound from the front wheels when cycling the ESOF switch.
None of the vacuum lines look obviously damaged.
I have not checked any fuses yet.
I can still manually engage the hubs.
