Check fuse 13 in the fuse block behind the glove box.
One flasher for both. Looks like a standard relay but has different internals.
From the FSM:
The combination flasher is located in a bracket
secured with a screw to the underside of the upper
steering column support bracket, to the right of the
steering column under the instrument panel. The
combination flasher cannot be repaired or adjusted
and, if faulty or damaged, it must be replaced.
