1974 Ford Bronco turn signals

I tore the bronco apart for paint, put it back together now my front turn signals do not work, the back is fine and the left side marker lights come on and the left front marker light signals as it should the right marker lights do not come on at all and the front turn signals do not work but the parking lights do work. I changed the flasher just to be sure but no luck. any ideas?

thanks, john

front,just no turn signals,and like I said the left side lights come on and
work. any other ideas? thanks, John
