At 18 years old this vehicle is in the Sunset of Life. GMs are notorious for transmission problems and at this point the repairs will probably exceed the value of the vehicle! Most likely the problem is with the ABS wiring going to one of the front wheels. The ABS, traction control, and Stabilitrac all work together and when the computer sees a problem with one system, all are disabled, and so all the lights come on. If this is not a wiring problem that can be fixed reasonably easily my advice is to get rid of the vehicle. Jim
