Pontiac Repair: 2002 Aztek, aztek, awd

Question
The "AWD Disable" light continuously stays on and the AWD does not work. How can I repair this myself? Also, the Brake light comes on and stays on (just put new brakes on and knuckle bushings) it "ding ding dings" constantly. The anti-lock brakes do not work. Help?

Answer
you need to find out what the codes are, once you get that info you can start diagnosis, without that info you are really just running blind, it could be many things.  You say you put new knuckles on, did you damage any ABS wires or forget to plug the sensors back in?
