Driver Side Brake Light Out

[ND76Bronco]

I have a 76 and the driver side brake light and rear turn signal do not work. I have tried replacing the bulb, however this did not work. I know that the next step is replacing the actual turn signal switch in the column. Does anyone know how to do this. Any pointers are greatly appreciated.

Check the wiring plug between under the column, I had a loose wire there that causes this to happen.

driverside turn signal work?

both front turn signals work and rear passenger turn signal works. Only the driver side rear turn signal/brake light don't work.

Have you checked the contacts & ground in the socket? It's not unusual to have a little corrosion show up in there over the years. I just got all of my my exterior lights working (Only the front parking lights worked at first), & all of the problems were either bad lamps or contact issues. It's worth checking.

Another piece of info is that the hazards stop flashing when I hit the break. i don't know if this is normal or a symptom of the problem.

you have a problem most likely from the turn signal switch back to the left rear bulb. step on the brakes and see if you have 3 wires total at the column connector area with 12 volts present. i is brake signal going up the column and the other 2 are going to the rear of your truck. that rules out a turn signal switch issue and means its simple wiring/bulb/ground issue.

That's normal.

Need to check for voltage on left side wire between column and rear lights with brake on. Early years was green-orange late years was yellow-black. No voltage means problem is closer to column.
