the switches are known to go bad, when you replaced it did you use oem or aftermarket? I see a lot of reports that the aftermarket switches are garbage.
can you post a picture of the switch?, if it's the same as the 00 you can try holding down the 4wd or 2hi button and then start it up, then release the button and see if it switches, the lights may stay lit up but you will be able to tell by driving or listening it engaged or disengaged if it does then it's the switch for sure.
any other ideas @07Burb @bigfootchiro
I also try the holding down of the switches but nothing
ok well it was worth a shot, one of these guys I tagged will answer back at some point with some other ideas or more info.
have you checked the wiring harness's under the truck? did you drive thru any water recently? if the harness got wet it could be causing a issue.
check the fuse box also
How long after you swapped switches did this current phenomenon begin? Have you pulled the positive cable off your battery as a sort of re-boot? Are you able to put a scanner on it to see if it has any codes?

Seems like it could be as simple as a faulty ground wire or maybe the switch has gone bad within a short period of time. I know you said it's OEM so you wouldn't expect that but even OEM parts can be faulty and go bad after not much use. Maybe try another switch and see what happens?

Before buying another switch (which is prone to failure on these trucks), recheck the grounds, fuses, front actuator harness, and even check the harness at the transfer case itself. It is definitely electrical, so need to trace every aspect in the circuit. Usually if the front actuator were bad, all of the lights wouldn’t light up, if I remember correctly.
Thanks guys.
I had the new switch in for about 3 months, don't drive it much.
Did not go thru any water or tall brush.
I have checked the fuses and disconnected both leads on the battery for 2 hours. No help.
Anyway I will get back to it this weekend.

Have you used 4Lo since replacing the switch?
Yes, went thru all the selections, it worked fine until this issue popped up.

Not to say this is the cause, but after extensive research of reading through many forums, websites, etc about this issue, and my own experience, 4Lo seems to be a common denominator with causing this issue. Do I know what it is? No... but that’s what I’ve found
It would be helpful to get the codes, might point us in the right direction. In what part of the country are you located?
Got it figured out. For some reason when I checked fuse #2 last week it tested ok. However the truck was off. Today I started the truck and pulled the fuses again. Tested it with a meter which it was good. When I inserted it I heard a couple clicks and this resolved the issue. The lights on the switch went out except the 2wd light which is expected. I went back thru all selectors and it all works.
Not sure why this happens but know for next time.
THANKS GUYS!!
Y'all have a Merry Christmas!
