Why are looking for it? Are the turn signals flashing rapidly,if so check the bulbs?If one burns out the flasher will flash rapidly.If it doesn't flash at all it could be a fuse burned out.I don't think there is a flasher like older vehicles had.I think its intergrated with a few other things but I not 100% sure.
With the engine off, key on, wait for the warning chimes to stop, then select turn signal one direction. Listen for the relay clicking and follow the noise. It should be behind the instrument panel to the right of the steering column somewhere.
remove panel covering fuse box, next remove the screw holding the heater duct work extension, with the duct work removed you can reach the flasher box cover by reaching up under the dash, remove cover from the box, then remove the flasher, the heavy duty replacement flasher is "taller" and the cover will not fit over it, reverse to close
