1995 Blazer 4x4 Problems

I have a 1995 Blazer. I was running in 4wd High for a while a few weeks ago and when I got out of the snow I tried to switch it back to 2wd. When pushing the 2wd nothing would happen. Eventually the light when off as I kept trying it but later the 4wd light would come back on without me knowing it was still in 4x4. I had to put it in Neutral to get it to go back to 2wd. Now when I push the 4wd High button nothing happens. I put it in Neutral again and push the 4wd High button and the 4wd Low button blinks a few times. Does anyone know what is going on???

What transfer case?
3 button shift buttons or with auto4W shift button?

Have you checked for transfer case codes?

Was you running on dry payment in 4W?

Have you check fuse and wiring?
