Headlights work but dash lights and parking lights are dead

tell good and bad, not just bad things.!
car starts and runs and drives ok? day time?
dash dimmer turned down, kids played with dads car?
well tail lamps dead (really are up to 10 or more parking lamps dead, is blow fuse or BCM failures.
why not scan the PCM see DTC errors first. save tons of work , if DTCs are there.
cars have 2 or more fuse boxes. cab and bay(engine)
did you check them all?
if car drives, I will say why parks fails. front and rear and sides of cars. are park lamps as are license plate lamps.
the BCM body brain on this car is SJB smart junction box.
SJB Fuse F2 and F3 good
and the HL switch not bad, and park switch there good
the SJB has CPU brain and a park relay
if the CPU sees park turned on it closes the park relay in SJB
there 8 park lamps.all 8 lamps run off fuse F3
so if one lamp works, then F3 is good if all 8 are dead F3 is blown
or the relay is bad.

these words assumes car runs. (engine runs)
and the battery is not dead
nor battery at 10vdc or less.
I check all that and all is covered in the service manual I just read.
for you.

THE CAR HAS LIKE 50+ ELECTRICS DEVICES,
ONE IS HEAD LAMPS THAT WORK KEY OFF DO THEY
IF NOT FIX DEAD HEAD LAMPS FIRST. FUSES.
IS STATER MOTOR DEAD
IS ENGINE DEAD
IS TRANSMISSION DEAD (ENGINE RUNS)
DOES DASH HEATER BLOWER WORK
DOME LIGHTS DEAD?
BRAKE LAMPS DEAD
TURNS DEAD
PARK LAMPS FRONT AND REAR AND SIDES DEAD/.
SEE, HOW COMPLEX 12DC POWER IS? AND MORE LOTS MORE. EVEN A DEAD RADIO

My 2006 kia Sorento ex .Instrument panel lights up when the headlights not on .I notice it when applied the brake mostly at night when park it in my driveway with engine off .

These are all different circuits. The brake lights are on a 10amp fuse - the headlights are on a 50amp fuse - and the parking and dash lights are on a 20amp fuse.
Do you have power going into the headlight switch and the brake light switch ?

No. Dash lights being out could be a bad headlight switch, since the dash lights are routed through the headlight switch, not the dimmer switch. Park and tail lights also controlled by the headlight switch.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????18

is your battery dead? turn your headlights on. do they work? if not,then the battery is dead. your car will not come out of park unless the brake lights come on. if the batterys dead,the brake lights will not come on. try a boost from another car. another solution,brake light fuse is blown.look under the dash or on driverside dash panel for fuse panel. look for a brake kight fuse that's blown. have you tryed applying the brake pedal with car off to see if the brake lights come on?hope this helps and thank you for choosing fixya.com

try replacing the dimmer switch

Look up under dash where brake pedal pivots, you should see a switch that is activated by pedal arm.

Sounds to me like you may have a instrument cluster problem.
