4x4 light out

I have a 02 F350 and the 4x4 light on the switch doesn't come in High or Low and the transfer case doesn't engage.
The 4x4 light on the dash flash for a second at start up.
Any clues for what I should look for?

Your xfer shift motor is probably dead. It needs to shift to 4wd to apply power to the light.

Disconnect the two-wire connector at the servo motor on the transfer case, and hookup a test light to the two wires.

With the engine running, turn the 4x4 switch from 4x2 to 4x4, wait a few seconds, and switch back, and watch the light. If the light comes on, the servo motor is bad.

If the light does NOT come on, you have a bad fuse or shift relays, or something else is going on.

After doing the test light thing, report back and let us know what's going on.
