WHY DOSE MY DASH NOT LIGHT UP WHEN HEAD LIGHTS ON

double posted, why do that.
its answered already,
the "meter fuse"blew.

all warning lights out,
or do you mean the parking lamps out in cluster.
there are scads of waring lights, name some.
the CEL lamp tops list, if out the engine my not run.
does it run? do head lights work and all other lights.?
is the battery in car charged," top 12.6v rested. and you can drive say 10 mile with head lamps glowing full bright?
that be good to know.

turn signal switch or flasher unit

Could be a blown fuse or the switch. start with checking all the fuses... or at least the lighting fuses. more info is needed... year make model but start with fuses

Not totally positive but I believe on your Toyota there are two places that fuses are located. You stated that all fuses under the bonnet are fine and I assume that means under the hood. The other place to check for a blown fuse would be under the dash instrument panel usually located directly above where your left knee would be while sitting in the drivers seat. Hope this is of some help. Good. Luck.

some main fuse boxes are under the hood in a square black box, some autos hide them under the steering colume under the dash.

Check the head light switch and the ground of the fuses.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

WHAT YOU MIGHT CHECK IS THE FUSE FOR TAILLIGHTS, OR DASH LIGHTS. THEY WORK OFF THE SAME FUSE. IF THE FUSE IS BLOWN THE HEADLIGHTS WORK BUT NO TAIL OR DASH LIGHTS

check your fuse penel under the left side of the hood there are 2 fuses for head lights there good luck

The dash lights and tailights are on the same fuse link. everything else will work like brake lights and turn signals but this one fuse causues alot of problems. Sometimes this fuses isnt marked on your cover so you might have to look in the maual to find the right fuse . some will be under the hood some will be under the dash .

Good luck to you all on finding this little fuse hope you find it before the cops pulls out behind you when its dark :)
