Dashlights and temperature dash lights not working

Hi, recently my dashlights just stopped working. I turn my headlights on but my dash and temperature control doesnt light up. I took the dash apart checked the bulbs, they all work fine. Checked the fuses and they dont seem to be burnt out. The only thing that works is my turn signals, p-brake, and check engine line has come on a couple of times. Any solutions???

    I didnt check the bulbs behind the temperature control though, would that brake the circuit if they where burnt out?

    It must be a fuse, there is no cover on the fuse panel w/ diagram, cant find one online. So im just gonna try a multi-meter

    i have a similar problem, in a 2004, the headlights are on but the lights on the dashboard are still brighter as if the headlights were off and the shifting lights (P,R,D.....) are off too. i´ve tried to find the burned fuse in the passengers fuses, also in the little one at the right under the hood and in the bigger one under the hood next to the washer fluid on the left and they all seem to be perfect. I can´t find the fuse resposible for such problem in the owners manual, the only thing that comes to my mind is that it might be a relain (small boxes) or a burned contact. if anybody has the answer please email me

    My Shift light (P,R,D...) arent on, the backlight for the speedometer and odometer dont light up. The rear running lights dont come on either.(but the blinkers work). Ive checked all the fuses and they are all fine. Can the relays go bad?

    have you checked the dash switch that controlls how bright the dash lights are?

  • mlusk May 11, 2010

    have you checked the dash dimmer switch that controls the brightness of dash lights?

Turn on your headlights and check to see if your taillights are working. They act as a fuse to your dashlights, its a safety thing

Replace dimmer switch. Your tail lights should also not be working when you turn on the headlights. OR replace daylight sensor on dashboard.

SOURCE: How to fix a brake light

all lights must be working in order for the lights to work in some's possible that you may have a bad ground wire to the light socket or the you may not be getting power to that socket, which means you have a bad wire. Check to see if you're getting power to that socket with an electrical tester first.

SOURCE: turn signals dont work bulbs/fuses are good.

check to see if the emergency flashers work if they do its its either a wiring problem, bulb, or socket the bulb fits in. if it does not work than the flasher is the problem. it is located underdash on driver side in the kick panel( to left of the brake pedal) it is a blue or grey sguare relay looking plug. if it is factory flasher it will say flasher with the part # on it. it should also say toyota on it. good luck

SOURCE: hi i have an 1986 toyota 4runner the dash lights

The tail and marker lights and Instrument lights are on the same circuit so both will go out if the fuse for this circuit blows. If fuse continues to fail, check the tail light or marker globes, including the globes for the number plate, for a globe that may have an internal short causing the fault and replace as necessary. As you have already checked the wiring near the light fittings for any chafed wires that could be shorting to the body causing the fault, then a closer inspection of the wires inside all the light assemblies for any shorts may be needed.

It could also be that the instrument dimmer control has failed and is causing the fault. The electronic bits inside the dimmer control for these lights sometimes go faulty. Try disconnecting the connecting plug on the rear of the dimmer control and checking if fuse still blows. If fuse continues to fail, then the fault in the tail and marker lights circuit.

Remove all the tail, number plate and running light globes from the light assemblies and leave the instrument dimmer control disconnected and check if fuse still blows.

Disconnect the plug near each of the light assemblies to see if any of the individual assemblies is causing the fault. With all light assemblies disconnected and fuse continues to fail, then the fault must be in the main wiring loom some where.

If you have a Multimeter, it could be used to determine which light assembly has a fault between the lamp supply and earth connection.

I have no dash lights or headlights

since the dashlights and the headlights are on separate fuses and i figure that you have checked your fuses i would look into replacing your headlight switch. headlight fuse works the switch the switch tells the dashlights to come on and sends a signal to a relay under the hood that tells the headlights to come on.

Headlights & dashlights turning on & off

Daytime running light module which is located under dash (around the area of the fuses) probably has a bad solder joint inside (if you take it apart). If not could be bad connection on one of the switches (like your dimmer switch)
