Depends on which range you start in.
Well if the actuator isn't letting it go from 4wd to 2wd the I guess the same would happen from 4lo to 2hi since it still needs to disengage the front axle?

Replaced the actuator a little bit ago, and still not working. So far I'm down $93 with nothing to show for it.
So that leaves the encoder or dash switch. I get some various signal voltages from each range, but don't even know what they should be.

You need a scan to pull codes for the transfer case module and to check data. This would cost less than $93 even at a dealer. If you were closer I'd help.
Not a common code which to me leads to wiring damage in most cases.
