1991 Corsica Right Turn Signal Problem

Hello all, Glad I found a forum for Corsicas, I could use some help. For the last year or two, my Corsica's right turn signal would not work. You could switch it on and off to simulate the flickering of the turn signal, but it would never click on and off like it's supposed to. I can work it by flipping the signal on and off to simulate the turn signal, but I want it like it's supposed to be, automatic. Is there a part I need, or something Inside I need to service?

Check the bulbs on that side very carefully. Usually that is the problem, must check front and back ones and check both filaments in the ones (rear) ones that have two, such as brake/signal bulbs. If they are OK be sure that both filaments are burning by having someone turn these on and off with you watching the lamps. I have seen old sockets go bad, can be easily replaced at any parts store. There is a flasher in the fuse area (it is round) but doubtful this is bad...
