You know that every time you pull into a gas station or get a crowd at the local car show your baby really turns heads. Well, the same is true when driving at night. You just don’t want to been seen but need to be and having a faulty headlight switch is not only inconvenient but down right dangerous. Over the years, these switches deteriorate leading to bad rheostats or simply out right failure. Symptoms may include a burning electrical smell from your dash when your headlights are on, inability to dim or adjust your instrument panel lights, poor or faulty movement of the mechanical parts or flickering of the lights. Even though your headlight switch is fairly simple to replace, we always recommend consulting your Corvettes service shop manual. First, you will need to access the back of the switch where you will find a small 1/4 inch button. Pull the knob while simultaneously pressing the little button. Your headlight knob should then come out. Next, unscrew the round nut that holds the switch to the dash. Pull the switch out from behind the dash and unplug it from the harness. Then, just reverse the actions to re-install. It’s that easy.
