No tail lights or dash lights???

I have a 99 Tahoe and the tail lights and dash lights have quit working. I still have break lights and head lights though.

I have checked the fuses and all of the bulbs, they are ALL good to go. Any ideas what I have going on??

Thanks!

If ALL of the fuses are good...

Check the headlight switch.

They go bad all the time...

How do I check the switch? Do I have to disassemble the dash to get to it?

I would like to thank the people that replied to this problem. I found the problem and I now have lights again. It was the plug on the back of the light switch that jarred loose. Popped her back together and she works fine now!

Thanks!!!
