Disconnect the negative cable from the battery. The flasher relay on 1993 and 1994 models is located on the interior fuse panel, while on 1995 and later models, it is found under the instrument panel to the right of the steering column. Remove the flasher by pulling it straight out. Install the new flasher unit, ensuring that the metal contacts align with the slots in the fuse panel, and press the flasher firmly into place.
