The other day I am hauling some straw/hay from down the road and I am running with the hazards on. Sometime down the road the hazards stop, no turn signals either. I check all the fuses and replace a couple that were blown, don't even remember what they were for but they were unrelated to the flashers. I also replaced the flasher relay today, still nothing. Multi function switch. The cruise, wipers, brights, all the lights work fine. Just no turn signals/hazards. Luckily I have all back roads to work, but I do get the occasional county boy behind me. - - - Updated - - - Actually now I remember replacing a 10amp fuse with a 20 amp fuse, something to do with trailer lights. So maybe that fried the multi function switch.
