Lights inside the car. Dome light, courtesy light, etc.
None of the interior lights work so I think it might be a fuse?
Either by opening a door or turning on the interior switch...
how do you remove dome light lens on 2008 trailblazer
how to turn off dome lights to my 2005 navigator
check for a blown fuse in the fuse box.
you have a short to ground . have it check soon ! could be a door switch .
Perhaps you turned on the interior lights when you were adjusting the headlights?
It powers interior items such as dome lights and radio memory.
You probably turned them on by accident. They are controlled with the same pull switch that turns on the headlights. By twisting the switch to the far left it will click and the dome lights will turn on, by twisting it to the right it will turn off the interior lights and will then dim the dashboard lights.
Press dome override button 3 or 4 times till you here a beep to put headlights and interior lights back on auto
If the dimmer switch for the dash lights are turned all the way to bright and then clicked one more time the interior lights will come on and stay. Try turning down your dash lights. It might also be a broken or bent door pin.
