Ok, I got a 2000 with the 4 button switch. Mine will not shift into 4hi at all and will shift into auto 4wd most of the time (sometimes it wont go in that either). Then once it's in auto 4wd and I hit the 2hi to take it out, nothing happens. But if I hit the 4hi button, the 2hi button will light up and it will go into 2hi. Sometimes it takes several attempts of pushing either the 2hi or the 4hi button for it to go into 2hi. Usually it's the 4hi button being pressed that makes it shift back into 2hi. Any ideas???
Why couldn't they have just stuck with the good old manual shift lever on the floor? Sometimes I really miss my old 85 Blazer.
