The Hazard and the brake lights are a different circuit than your turn signals. The key mustt be on for turn signals and both lights frt. and rear should light and blink. If oney on lights up the other bulb mustt be replaced. If both bulbs light but don't blink it is your flasher. There are two different flashers in your car. One for turn signals and one for 4-way flasher. The four way flasher is normally close to the fuse box and the turn signal is up by the steering column. The # of the bulbs are #1034 & #1157.
