No brake lights,turn signal

I replaced the steering column and the turn signals worked then quit and the right back brake light has stopped working the driver side still works.I think its in the column somewhere,but I’m not sure where to start looking,the hazard lights all work,the headlights work,just no turn signal or rear passenger tail light,the reverse lights work too,any help appreciated,I have been restoring this for 7 years I can drive it but want the lights to work.Thanks
