Symptoms:
>4-way flashers work as they should
>with power on, and with both the old flasher relay or a new one, both left and right turn signals flash fast when either side is activated by column switch, as when a bulb is out, but bulbs are fine (they work when 4-way is activated)
>Here's the kicker: with power OFF, when right turn signal is activated by switch on column, it comes on steady both front and rear (not flashing). This does not happen on left side.
>Could there also be a connection between this problem and why my left fog stopped working (i tried a new bulb).
I'm inclined to think the problem may be in the column switch, but looking at wiring diagram I'm not convinced. However, a couple forum threads suggest a relation, even to the fog light problem.
