It might just be the fuse is blown.
are you sure the lower brake lights your talking about aren't tail lights. That's my guess. Check in the fuse box for a fuse labeled dash, illumination, parking or something to that effect.
There is a switch that controls the brightness of the dash illumination. You can adjust them from bright to dim and off all together. Be sure the switch is not in the off position. The dash illumination has its own fuse, check that also.
lights are very dim
Fuse should be marked and also control parking and tail lights
Yes, the radio illumination lights in a 2011 Buick Lucerne are typically protected by a fuse. You can find the fuse for the radio and its associated components in the fuse box, which is usually located under the dashboard or in the engine compartment. To identify the specific fuse, consult the owner's manual for the exact location and amperage. If the illumination lights are not working, checking this fuse is a good first step in troubleshooting the issue.
The fuse probably blew that controls the dashboard lights.
Your brake lights are out too! Replace the fuse.
On my zx2 there is a button on the lower part of the dash by the drivers door that you can brighten or dim the lights... Not sure this is your problem but it is worth a try ... I use it to dim them when driving at night..
The car going down hill symbol on the speedometer. What does it indicate?
Have you checked the fuse block, for a blown fuse.
Brake lights and turn signals are on a separate circuit from the tail lights. Tail lights are on the same circuit with the dashboard lights. If the dashboard lights aren't working either, check the fuse. If they ARE working, check the headlight switch.
Check with your driver's manual, it will show you where the dash illumination control is.
