'94 Cavalier turn signal problem. Help!!

I am having a problem with my turn signals. They dont work!! When they quit they were flickering very fast. Heres the thing though, I changed all my blubs, checked all my fuses, replaced the flasher, replaced the signal arm assembly in my steering column, and they still dont work. My 4way flashers still work and my parking lights and cruise ctrl. still work

Besides taking it to a shop and paying out the ass, is there anything else I should try to find where the problem is?

Please help. thx.
