right front signal light works sometimes then when i turn the ignition off and try the right signal again it dont work again.

check the plug at the light for corrosion. when a car gets older it tends to get a lot of corrosion in the back of the plug and can cause a bad connection. also check your wire as far as you can trace it back from the light. check for britle parts in the casing and tape them if you find them. you may have to replace the wiring back a ways if its bad enough
