Hey all, New User here. Ive used this site plenty of times but I figured Id join anyway. I have a 95 S-10 blazer. When i push the 4 HI button it lights up, but does not engage the front wheels. a Vacuum hose possibly? Any suggestions would be nice.

Thanks guys

 

Run through the '4wd no worky' thread in the Tech Article (DIY) section. It goes through the possibilities fairly well. A link to it can be found in the Tech Article (DIY) Index which is linked to in my signature below.
