The dash lights and tail lights ar on the same circuit. After brining mine to a so called auto electrician, and stripping all of the light connections and checking fuses, connections etc it was determined that dash lights and tail lights were not working as there was break in the wiring somewhere. This would have invoilved weeks of tracing the complete lighting loom, or wiring a separate line to the tail lights and dash lights and a fusable link for both at considerable cost, and devalue to car. I was unwilling to trust the findings of these guys so when I got home i took off the steering colum cowling and disconnected the light switch block connection. I used a simple circuit tester to see if there was power coming to and from both sides when lights on and there was. I then pressed the block back together but really hard so they were all definitely connecting and hey presto... dash lights and tail lights now working perfectly. Sometimes the simplist explanation is the best. Give it a try.
Check your dimmer switch under the dash first.
lights are very dim
The fuse probably blew that controls the dashboard lights.
If all of them stopped working at once, it could be a fuse. Find the Fuse box and test the one that connects to your dash. if the fuse is bad, replace it.
Your brake lights are out too! Replace the fuse.
SOUNDS LIKE A BLOWN FUSE DOES YOUR TAIL LIGHTS STILL WORK? 99.9 % THE TAIL LIGHTS ARE ON THE SAME CIRCUT AS THE matker LIGHTS -TAIL LIGHTS
Tail-lights and dashboard lights are on the same switch on the dashboard and on the same fuse. Check the fuse and if that's not it check the switch. Check the fuse underneath the hood. There are some main fuses underneath the hood. I had the same problem on my Chevy P-U when I lowered my boat into the lake, it blew the fuse underneath the hood and I had no tail or dash lights.
Probably the flasher unit needs to be replaced. This is an electronic switch which usually mounts underneath the dashboard.
The hazard and blinker lights are located behind the dashboard tray. To fix the fuse, you unfortunately had to take the dashboard out.
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.
Your dashboard lights suddenly not working is almost always your indication that your taillights are out. If the fuse for your taillights is blown and you replace it, your dash lights should be fine.
Check the fuse or the wiring
