New Gen 3!... (but stuck in 2wd) what gives?? #1104035

Seeking guidance from the Montero-wise.

I'm stumped. Picked up a 2003 Montero with only 75k miles, had it shipped over to the NW from Hawaii.

Not sure it's ever been in 4wd in it's entire life. Here's the symptoms.

-Flashing center differential light, all green wheel lights go out. Checked codes by grounding pins 1&4. Codes 33 & 35.
-Changed Front diff vacuum solenoid under airbox (did not fix). Cleaned out old solenoid, cleaned connectors (did not fix).
-When switching into 4 wheel drive the transfer case is silent, stays in 2wd no matter what selection.
-I checked the front diff actuator shaft for corrosion, was clean but I regreased anyways and manually cycled by sliding the shaft by hand.
-All vacuum lines are in place and seem to be intact.
-I've cycled the transfer case lever 100+ times back and forth in the last 2 weeks to no avail
-I've drained & replaced the transfer case fluid with GL4 (no changel)

Next steps:
Clean all electrical connections around the vacuum solenoid and use dielectric grease to seal
Switch the vacuum lines on the solenoid and check to see if the front diff engages
If all else fails, try drop the transfer case and clean the switch connections with electrical connector cleaner

Does anyone have insight or direction for me? Thank you in advance!

Take off the t-case selector and look inside the mount? Perhaps it's just gummed up. My second LUV had that problem, just trying your troubleshoot.
