Yeah, that seems funny to me too, but it happened. So you're saying
that the
hazards operating is essentially the hazard switch telling it to run
both
turn signals at once? And when this happens, the input from the turn
sigs.
is negated, or has no effect?
Exactly. Reading the schematic for your car should show you how
it has to work. (There are variations on how they did it, but
they're all substantially the same. The big difference is whether
the [single] flasher is integrated with the hazard switch or not.)
