I have a 00 Chevy Blazer and I started it and the 4 wheel service light came on and the 4 wheel button lights came on too. When I drove it I couldn't go over 20 without it shakin and the lights never went off. I hope someone has an idea about this problem. thanks J

What do you mean shaking? Is it in 4hi, or 4low? This may work, but probably not -try pulling the fuse, let it sit, and reinstall the fuse. This may reset the system and be alright. If ths doesn't work, you'll have to get this system scanned with a capable scanner and see what codes are stored. With the service light on, it has a stored code.
