In that case, you probably don't have tail lights or clearance lights either.
Check the fuses. If that's not it, you may have a faulty light switch.
on my 1996 Saturn it was a blown fuse under my hood my headlights worked, but the lcd light or my back lights on my car didnt work.
the dash and radio lights are supposed to dim when the headlights come on. Make sure you have the brightness of the dash lights turned up as much as possible.
my headlights and dash lights stopped working on my 2007 yamati strada RX150
The dash lights will dim when the head lights come on. Check for a dimmer switch on your dash. It allows you to adjust the dash lights so they are not too bright and affect your nighttime vision. It may be set too low.
DIMMER SWITCH FAILURE.
First, check the tail lights. Turn on the headlights and see if the tail lights come on at the same time. If the tail lights come on but the dash lights don't, it's probably either the switch or the bulbs. If NEITHER come on, it could be the switch, the fuse and of course, still the bulbs.
is there anyone who knows the answer?
This can be due to a bad headlight switch. If it goes bad, most of the time you have no dash lights or headlights
headlights and dash lights in 2001 sunfire wont turn on.
What year is the vehicle? Did you check the fuse?
Check your fuse for tail lights. I think the dash and tail lights are on the same fuse so you know when your tail lights don't work. Might have a short or an open in that circuit.
check fuses and connections at the headlights and the switch in the dash, make sure your headlights are good ;-) that's a start...
