Hi,

I have a friend of mine with a 2003 Tahoe that is experiencing intermittent power to the 4x4 push button panel. Just yesterday I checked it out and we swapped to another switch. To our surprise the light stayed on and the switch performed perfectly.

We then switched back to the original push button control to confrim that it was indeed the culprit and lo and behold that also worked ! We left the original one in thinking that it may have been a bad connection and that the problem was solved.

Unfortunately, on the next startup the same problem reoccurred. All the lights cycle on when starting but no power to the panel when you release the key to run. I would appreciate any feed back.

Thanks, John

Welcome to the forum.

Someone here can probably lend a hand.

I might toss in the new switch and wait for it to fail. That would be a better test to me.

Is the SERVICE 4WD message ever on?

Thanks for the welcome. Seems like a great forum!
We wound up changing the encoder on the transfer case and all seems to be working well. Thanks for the input.
