My low range will engage and work fine but when I try to put it in high range the indicator lights go out and nothing happens. Every once in a great while the high range light will stay on, but it doesn't engage and about a mile later it goes out again.

Check for power to the 4wd actuator on the transfer case. Check wiring and for power. If there is power, remove the actuator and check for operation. The actuator itself may be bad.
