Turn signal and hazard light not working?

Okay, if none of them work there are a couple items to check. First check both fuses, they are in the junction box under the left end of the dash. One for turn signal, the other for hazards. If both are good, If the fuses are good, we need to check the flasher unit and the bulbs and circuits. The easy way to do that is to remove the flasher unit, Now use a short wire and connect it between terminals 1 and 2 in the flasher socket. Now turn on the key and select left and then right turn. The lights on the selected side should light up. If they do remove the jumper and use a simple test light to check the ground. To do that, connect the test light to battery positive. Now touch it to terminal 3 in the flasher socket. The light should come on. If it does and the lights worked in the earlier test, replace the flasher unit.
