Turn signal comes on but wont blink

What is your question?

My turn signals come on but dont blink, my emergency flashers however blink perfectly. They are on the same relay (which we have tried replacing 4 times just in case we had a bad one) and much of the same wiring which we have checked with a multimeter. We have also replaced the turn signal switch in the steering column three times ( one was bad) each time it would make the signals blink for about 5 minutes then stop again. We have checked/replaced all the bulbs and fuses. I have seen many other cavalier owners post a similar problem on other sites but they never get any answers.
