Does anyone know if it is possible to disable the ABS brake system on a 2002 trailblazer LTZ with 80,000 miles. The service brake light comes on about 80% of the time. I have also had some other minor problems with the electronics. The dealer wanted to start by replacing a $1,000 component. I have driven many miles without ABS so I think I can get by just fine without it. My experience with these type of systems is if they are not built right the first time, they are a money pit to fix. I will probably trade it for a new GMC Terrain, depending on how many more problems I have with the Trailblazer. Also I keep getting a service the OnStarr message, how do I disable this?
