On my way home from work I went to make a right turn and found that my signals are coming on but not flashing. After some quick diagnostics, I see that the hazards are also doing the same thing. None of my bulbs have failed and my brake lights (which are shared with the signals and hazards) work fine too. I am wondering if this truck has two different flasher relays (one for turn signals and one for hazards) or just one piece.

One unit for both functions, but it's an electronic flasher; not the more reliable thermal flasher.
