[Mrich0908]

I bought a 6.5TD k2500 burban . I just got head gaskets fixed took it out for a drive and its stuck in 4x4 . I went to select 2hi no light . I listened to see if anything was switching in the tcase nothing.Checked fuses all fine. All grounds are present and hooked up.
Any suggestions. Any one know how to manually disengage 4wd for the time being.

Odd after all that gave it a smack and ut started working . Shifted from 4 to 2wd no problem.

Percussive maintenance wins again!

I'd guess the switch is probably just on it's way out.

EDIT - Unless it's the floor mounted selector, I'm only familiar with the push button.
