4wd problem

[dukebear7]

Hi, first time on the forum and I have a 4wd problem. It's a 1999 Tahoe and there is no lights lit up on the push buttons for the 4wd. I was told the transfer case was replaced and didn't work since. I was told it could be the acuator but that was replaced and also was told it could be the transfer case switch but can't find it. Can someone please help it's driving me crazy.

none of the buttons light up, even 2wd?

Correct is it electrical

It may just be the buttons/control panel itself

first step would be to pull the switch out and make sure that the wiring harness is firmly plugged in, then the next step would be to either test the connector using a voltmeter and see if you have power or see if you can find someone with the same button setup, plug theirs in, if it works then your problem is a bad button panel

Check the fuse for the 4wd, the harness may have been pinched when the Tcase was replaced and shorted/ blew the fuse....

I did that already and the fuse is fine. Is there another fuse that I might be missing, I looked in the inside fuse panel in between door and dash.

There are 4 fuses for the electronic transfer case.....
