Hi all,
Just recently purchased a 2003 Tahoe LS & put a new transmission in it. It’s running great now, but the cluster lights in the dash are sometimes not lit up, sometimes it says it’s in 4 low & if the lights are on if at all, when I press 2 high it just sits there & blinks & wont engage. When it says it’s in 4 low, it’s really in 2 high. 2 high is all I have right now. I checked the ground wires at the frame & it looks ok. Could it be the fuse & if so, what’s the name of that fuse? Any help would be appreciated.

07 + ?

You do know you asked this on the 07 and up forum?
BTW: I have the same/similar problem with my 07 Tahoe. Maybe someone will help us both!
I suspect either the switch or encoder motor.
