The 4x4 indicators have no direct link to the 4x4 system, the cluster receives the command to light them up via the CAN bus from the PCM, and if there was a problem with your CAN bus you’d have a lot more problems and flashing indicators. Which leaves you with 3 possible causes, a bad contact plate, which should produce a DTC, however you’d need an enhanced scanner to retrieve it, a bum cluster or a bum PCM.
I THINK this is the correct state for the shift plate.
In 4Hi:
White - open
Violet/orange - grounded
Light blue - grounded
Orange - open

hey there, I have the EXACT same problem with my truck. key on, 4x4hi is on steady for the bulb check. Put it into 4x4hi, the light will come on intermitently, sometimes it will go off for a while, then flash on and of for a while (like a loose connection flash, very inconsistent) then it will be on.
What did you fix to take care of this problem?

I think it may be on the passenger side fenderwell.
