I have a 2000 Z-71 Silverado. I am having issues with my ABS and Brake panel light illuminating just above my speedometer. It used to not come on very often and now it will come on religiously. Not sure what is causing it. Could it be a bad sensor or module? If so, How in the heck do I correct it? Brakes are still working, just very annoying at this point.
