I've done quite a bit a reading and some experimenting on the flashers, especially in regards to LED signal conversions, but don't consider myself an expert. The OEM flasher has three wires, one for hot, one to the turn signal switch, and one to the auto-cancel mechanism. To replace the OEM flasher you will probably need to go to the dealer and even there might have problems getting one. Other than that almost any flasher will do if you are using standard signals but you will lose the auto-cancel capability. Most are less than $10 at any big box auto store. If you converted to LEDs and have not installed ballast resistors you will need a electronic, "low/no draw" flasher. If you cannot get an OEM replacement and want to maintain the auto-cancel feature (assuming that is not the function that died in your old flasher) you can hook up a new flasher in series after the old flasher.
