Checked all fuses & bulbs & they're fine. Tail lights work. Front turn signals & hazards work. Brake lights don't work, window brake light doesn't work, rear turn signals don't work, rear hazards don't work.
It all points to a fault with a common ground. Find earthing points

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

has to be somwhere in the wiring for the tail lamp brk light. if the high mount works the switch is good. did you put the correct bulbs in? they may share a common ground independant of the other lights.

If your third brake light is working then the fuse, and brake switch are ok (it powers up all brake lights). The most likely cause is the column mounted multi-function switch, it consists of the turn signal, hazard and brake light controls, on the right side of steering wheel. You can check at the base of the column. There is a large black three-piece connector there that all the ignition, starter, lights, horn, cruise control and wipers all go thru. With the brake pedal depressed there should be power on the white wire (its on one of the end connectors terminal 1, very first wire, and should have pink wire directly beside it). If power is good, then check for power on the opposite side connector dark green wire terminal 6, and yellow wire terminal 7 (there are near the center directly beside each other). If no power on either (green or yellow) then the multi-function switch is at fault. If power is present on both, then the rear signals must also be out, and you'll have an open connector going to the rear lights.
