1. Open the glove box.
2. Remove the two screws that hold the glove box in place.
3. Pull the glove box out of the dashboard.
4. The flasher unit will be located on the left side of the glove box opening, attached to the fuse box.
The flasher unit is a small, black box with three terminals. The terminals are labeled "L," "R," and "P." The "L" terminal is for the left turn signal, the "R" terminal is for the right turn signal, and the "P" terminal is for the hazard lights.
To replace the flasher unit, simply disconnect the three terminals and pull it out of the socket. Then, insert the new flasher unit into the socket and reconnect the terminals.
Once you have replaced the flasher unit, reinstall the glove box by inserting it into the dashboard and replacing the two screws.
