So 4wd high will not work when I push the button it does nothing no flash click or anything. I replaced buttons on dash and electric shifter on tcase and still same thing!!!! its a 98 k1500 4x4 low works fine and goes in 2nd from low fine. When changing tcase motor it goes in 4x4 high fine with crescent wrench help!!# lol

Did you try unplugging the battery for a few hours? Let everything reset?

Only need to pull the 4wd fuses for 30 minutes to reset everything.

Check the fuse.

Check the fuse.

They were fine. You pull them to reset the TCCM and give you guidance as to where the problem lies.

I missed the part where OP said he checked the fuse. I was having a blinking light on 4 hi, but a solid light and clunk from the tcase on 4 lo. Fuse kept blowing. Turned out to be my actuator.

So disconnected battery and it worked one time now exact same thing no 4wd high

But you have 4lo?

 

[mtstclair]

Yes low works fine!!! These little problems drive me nuts lol

That's weird. Is it truly 4lo or is it going 2lo maybe? I mean the light shouldn't come on then, but the rest of this doesn't make any sense either.
