1. The blinkers work sporadically. One day they work perfect, the next maybe not at all. It seems like if I play with the wheel and the switch they will come back on. Maybe a ground issue inside the steering column?
I used contact cleaner spray on my emergency flasher switch. On my 720 the switch is on top of the steering column. Good place for dirt to collect.
It took some spraying and turning the switch off and on before the problem cleared up.
