Check the grounds at the rear. Do the high-mount brake lites work ok? Your lower brake lites and turn signals use the same bulb filament, just not at the same time. Your lower brake lites are wired through the turn signal switch. At the right rear, dark green wire is voltage for that brake lite, black wire is ground. At left rear, yellow wire is voltage for brake lamp, black is ground.
