Chevy Cheyenne 1991
 

Hi,

I am the owner of a 1991 Chevy Cheyenne, 3/4 Ton, Longbed, 4x4, K2500, with 350 Engine.
I have not shifted into 4x4, because something is somewhere defect. The 4x4 does not engage. In wintertime I can use my 4x4.
Can anybody give me some advise about the problem. I want to repair it in my garage at home.
Thanks for any help and advise.
Walt
