What needs to get fixed if your '97 Chevy S10 will go into 4x4 low but not 4x4 high?

First check the ground wire on top of the transfer case This depends weather your transfer case changes by electric motor or vacuum if it's vacuum most likely it's your check valve located on top of transfer case or if electric refer to first answer.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
