After diggin through the many resources here, I replaced my turn signal flasher unit because of erratic blinker flashing. It appears it worked to an extent. What I'd like to know is if the tail lights on the 1992 Seville are supposed to wigwag on each side. To clarify: There are 3 lamps on each side- one on the trunk lid and 2 in the fender pod. I switch it to the right blinker position. The trunk lid lamp flashes, the 2 in the pod do not, then trunk goes off and the 2 in the pod flash. Flip it to the left and it does the same thing but on the left side. They do not wigwag from side to side like a cop car. They stay on thier proper sides. They are orderly, at a normal flash rate, bright, etc so I don't think they are broken per se but is this how they are supposed to flash? I haven't seen a car do that before without mods and my lights had been screwed up since I got it so I don't know what "normal" is supposed to look like. I would assume (you know how that is) that all 3 lamps are supposed to flash together.
