4wd push button doesn't light up

    I have a 99 silverado with the auto trac and my 4wd doesn't work. The lights on the switch don't light up no matter what button I push. I've tried replacing the switch at my local dealers suggestion but that didn't fix it. If anyone has any suggestions I would greatly appreciate the help. Thanks

    The light won't come on? or it won't switch into 4wd AND the light won't come on?

    What I'm asking is will it shift to 4wd even though the indicator lights are malfunctioning?

    No it will not go into 4wd either. I checked the fuses and didn't find anything blown and I'm not sure what to do next.
