I have a question concerning a turn signal issue on my 24V - 1983 BJ40. The left rear turn signal does not work. The left side dash turn signal indicator works….although it flashes very fast, unlike the right side turn indicator which flashes normally. The 24V bulb is fine. I tried a new 24V bulb and the signal still does not work. The 4 hazards work all the way around except the left rear bulb. The right side turn signals work fine - front and back. The left front turn signal works. Is it possible that the switch is bad on one side only? Could there be a ground problem? I believe the ground is ok since the hazards work and flash fine - with the exception of the left rear signal? Any help / guidance would be greatly appreciated!
