Any car w/ red turn/brake lights often have same problem in my Cave,
Sneak PathPull all rear sockets out. Look at bulbs when On, in this case w/ park/tail lights On. Only 1 filament should be On.
Pedal or turn switches may have problems too keeping brake lights off.
If not controlled by BCM... likes has same taillight wiring setup as Fiero notchies.
