85 f150. My turn signals both front and rear stopped working along with brake light. All on the passenger side. Put new bulbs in last weekend so they should be good.

I checked the front with the bulb from the other side that is working. Still no turn signal. The bulb I took out was all white. No idea why it went out. Was a brand new bulb. Havnt taken the tail lights out yet to swap from one side to the other to check that but I'm thinking it will be the same thing.

Swapped the hazard relay from one truck to the other and no change. Bad turn signal switch maybe? They were all just working tho and its only on the passenger side.

 

I would suspect the turnsignal switch or the wiring in the column. That's the only thing that is common with the rear brake, rear turn and front turn lights. Since the other side works, then you know the brake switch on the pedal is ok, and the flasher is ok.
