From my Experience most of the time its a fuse that is blown. The dashboard and tail lights run off the same fuse
Check fuses? Could be a bad headlight switch/ Could be an open in dimmer rheostat?
change the headlight switch !
Typically this is a failure of the headlight switch assembly. See the question about how to replace the headlight switch in a 1991 Cherokee for the answer of how to accomplish.
To turn on the dash lights in a 1992 Mercedes 190E, locate the headlight switch on the left side of the dashboard. Rotate the switch to the right until you hear a click, which activates the parking lights and dashboard illumination. If the lights still do not turn on, check the dimmer switch (often integrated with the headlight switch) to adjust the brightness of the dash lights. Ensure that the vehicle's ignition is in the "on" position for the lights to function.
The rheostat on the headlight switch is bad.
The headlight switch on a 1993 Mercury Topaz is typically located on the dashboard to the left of the steering wheel. It allows you to turn the headlights on and off, as well as control other exterior lights such as the parking lights and fog lights. If you are experiencing issues with your headlights, it is recommended to check the fuse, bulbs, and wiring before replacing the headlight switch.
In a 2006 Ford Escape, the dimmer switch for the interior lights is located on the dashboard, to the left of the steering wheel. It is typically integrated with the headlight switch. You can adjust the brightness of the interior lights by turning the knob or sliding the switch up or down.
Replace headlight switch- dimming rheostat may be loose
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
To turn off the lights on a Honda dashboard, you typically need to locate the dashboard dimmer switch, which is often found near the headlight control or on the dashboard itself. Turn this switch counterclockwise to decrease the brightness or completely turn off the dashboard lights. If the lights remain on, ensure that the vehicle is in the proper gear and that all doors are closed, as some models may keep the lights illuminated when a door is ajar. Always refer to your owner's manual for specific instructions related to your model.
To turn on the fog lights on a 2008 Ford Edge, first ensure that the vehicle is in the "On" or "Run" position. Then, locate the headlight control switch on the left side of the dashboard. Turn the switch to the "On" position for the headlights, and then pull the switch outwards to activate the fog lights. If the fog lights are properly activated, you should see a green fog light indicator on the dashboard.
What year and model? Under what conditions? The dash lights are designed to stay on in certain models. Saab 900s from about 1987 on will have dash lights come on any time the ignition switch is in the ON position, whether or not the headlight switch is turned to ON.
