corsica signal problems

We bought a corsica and the signals wont work. We were told to check to fuse then replace the relay switch, well that hasnt fixed the problem. I was hoping someone would have some other ideas so we could get this registered for our 16 year old.

Please describe in more detail what is happening. When you turn on signal switch does the lights get bright, or do nothing? Have you checked ALL bulbs in turn signals, marker (side) lights, tail lights? you replaced the relay and checked the right fuse? Turn on lights and see if any do not light up, also do the tail lights get brighter when the turn switch is turned on. Are the signal light indicator lights stuck on in dash? If so, should be bad bulb(s) somewhere. May even have a burned socket or two. Check the lights/bulbs.
