What are the lights on the switch doing?

the lights just stay on. we can hear it shifting, but nothing happens, and still does not engage. we tried to pull he fuse out, didnt work, we tried to put it in N, then switch to 4, then park, still nothing. we tried going in reverse and drive a few times, still nothing.

Does the light change from 2wd to 4hi? Or will it blink then just go back?

There's a vacuum operated actuator under the battery tray. Hook up a hand vacuum pump and check that it operates and holds a vacuum. If it does follow the vacuum line back up to the solenoid that operates it on the firewall and inspect for any cracks that may cause a leak. Verify that the solenoid is receiving power when trying to engage the 4wd on the vehicle, and verify functionality of the solenoid by applying 12v to it. If everything checks out there, you are most likely looking at a failed transfer case motor as the problem.

No, these problems are 90% of the time electrical or the vacuum actuator problem. If the transfer case is bad it will usually make some horrible noises.
