I have a 94 cadillac deville and neither my brake lights or signals work. What can I do?

I have checked the bulbs and fuse box and they are all good. what else can I check for? I have all other lights but those.

check the wiring. Pop open your trunk and pull back the interior fabric to access the lights. Take a volt meter across the lines while someone tests the signal and brake lights and see if you get anything.
