97 ZR2 4x4 button problems

[guff]

When i turn the key the 4x4 buttons do light up. After it is started the 2 wheel button is not on(think it is blown bulb) I go to push the 4HI button and it doesnt do anything, no light no click. I can get it to go into 4Lo by putting it into N and then hitting the 4Lo button. When i do this sometimes no light come on, sometimes both 4HI and 4Lo are on and sometimes only 4Lo is on. And the 4x4 4Lo does work. I hit the 2wheels drive button and it goes back into 2 wheel drive. Any ideas. i havent tried unhooking the battery yet.

unhooked battery for 5-10 mins...........fixed the problem. 4 HI works like a champ

just a quick note, If you light bulb does blow, you will NOT have 4wd, this bulb actually completes the circuit, kind of a pain. I had mind go out while 4 wheeling and got stuck many times. I think it is a safety for stupid people, that way you can not keep it in 4x4

It could also be your transfer case that controls your buttons and controls the transmission to go into 4x4. My family had a 2001 ZR2 Chevy Truck and it went out and had some of your similiar problems. Check this if the battery thing doesnt work.
