RE: all instrument lights come on, guages stop working
i talked to one of the guys at work today who used to have a cavalier and he said he had the same problem. he recomended running a wire from the ground prong (fender side closest to the firewall) to the negative battery terminal. i tried it since it is easier than removing the dash and it works. now as soon as i finnish the brakes, tune up and fluid changes, i will have a nice reliable car. maybe this will help someone.
