abs problems can most of the time befixed by cleaning the hub and sencer mating serfice. one dealer told me i was using the truck all wrong. that was in 2004 when my truck was new. i had the abs kicking on and off and the light coming on. it seems chevy did not build any 4x4 for off road useage or gravle roads. when durt, mud gets in the way fo the sencer it goes nuts. my truck is a work truck and the first week i had it i was out in the woods. you should of seen the looks i was given. but clean the abs sencers up and you will be good to go. unless one has went bad.

for the light. you can bet its got the chevy grounding problem. simple test is to ground a wire to the frame then put it on the bulb. if the bulb lights you will need to clean or replace the ground wire to the bulb. chevy is bad about that. on my 85 chevy i had to run new grounds from the frame to the lights.
