My drivers side blinker and brake light doesnt work. Also the hazard on the drivers side doesnt work. My park lights work on the drivers side. Everything works on the passenger side. I've replaced all the bulbs and still cant get them to work.

Possible issue with multifunction switch or wiring in the steering column. Give me a sec to find wiring diagram.

Your lower brake lites and turn signal use the same bulb filament, just not at the same time. Yellow wire is voltage.
