Problem with my left turn signal not flashing. Both bulbs would light but not flash. Changed flasher, then they would flash, but one side flashed fast and other side slow. Pulled all the bulbs and found one with a different wattage than the others. Bought all new bulbs, (1156 I think), and now they work fine. Never thought the bulbs would be the problem since they were good, just the wrong wattage. Owners manual calls for 32 watt bulbs, which I couldn't find. Went with highest wattage I could find, 1156s, and they work ok.
