Brake lights in tail lights are out but the upper one works. Changed bulbs and fuses.
turn signals working but have sometimes not worked then start working again on their own.

Hi, may be an issue with multifunction switch? The lower brake lites and turn signals use the same bulb filament, just not at the same time. The lower brake lites are wired through the turn signal/multifunction switch. If you want to use a testlite at rear brake lites, to check for voltage, one side is dark green, the side is yellow, for wiring color.
