The digital dash board instrumental panel sometimes works and sometimes doesn't work. I purchased this car this year and have not been able to pinpoint the problem yet. I tightened up all the grounds that I could find and tried to determine which wire is giving me the problem but with no luck. I have been told that if the dash board lights while working appear strong and clear the instrumental panel does not need to be repaired but its a wire problem outside the instrumental panel, is that true? How do I properly fix my problem? Is there a professional in South Jersey that can help me resolve this problem?
