Can someone help with a 93 Buick Regal Tail light problem?
Tail lights are on a different circuit than brake and turn signals.
Do your front and side markers work?
Either blown fuse, bad switch, or bad relay.
It's tough to say which one........Sorry.
Check the easy things first.

try fixing the lights and the fuse
check the switch on the brake pedal
i check see if you have a bad fuse. then if not. then its a short in the wires.
There is a short or a ground issue. Get a Chilton's Manuel from your local auto parts and pull the schematic. There you will find where the lights are grounded. Sometimes moisture will corrode the connection and effect the tail lights. Also there is a brake light switch that is between the brake pedal and the colum. There may be a short there also.
