Guys, please...
If there's a non-working button, it won't switch over.
If the button back light is dead, then it won't blink.
I have the feeling it could be a missing feedback signal from a change-over detector at a transfer case. But I don't have the right wiring diagram,

Here's the 3-button transfer case description, diagnostics, and wiring diagrams for a 2001. Should be the same for a 2000 3-button ZR2.
