Check socket for corrosion-and make sure it is grounded
change the fuse if not replace flasher
If the center one works then it will almost certainly be 2 Blown globes.
blown fuse or turn switch bad
The only thing common to all those lights (but not to the center brake light) is the hazard switch. I'd check that next. On my 96 Century the hazards override the signals and brake lights meaning that the signals and brake lights must be wired into the hazard switch somehow.
There are several stores where they sell window lights, some of them include Gaebler, you can also purchase some window lights on the internet. Another store that sells window lights is Everest, they can also be found on the internet.
get a new window switch
Yes. I have found the schematic in the back of most "Haynes" manuals.
lights
The '67 has Front Turn Signals under the headlights, under the grill. The '67 has little front triangle windows for a two-part driver and passenger side window. The '67 has no rear side marker lights. The '67 has a light colored grill shroud, a bit grey. The '68 has Front Corner Turn Signals that run around front to side. The '68 has a one piece side window (no triangle openers). The '68 has rear side marker lights fashioned in the likeness of a Pontiac symbol. The '68 has a dark colored grill shroud, black. I know of no other significant body style differences. The wing window is the most obvious and is the easiest giveaway to indicate a 1967 Firebird.
File on the top left corner, and open new window.
