Right blinker does not work

My right blinker started off not working, and then quit completely and then went back to working off and on. So I took it in and had a diagnostic test done and was told it was the multi-function switch that a wire on it was bent and no good. We replaced it and it is still doing the same thing. Could it be the relay switch? Checked the fuses and they were good but replaced them anyways. Need some help. Thanks!
