Both Sides

  1. Turn hazard warning system on. If all turn signals come on, replace turn signal fuse. If new turn signal fuse blows, repair short to ground in turn signal circuit(s).
  2. If turn signal fuse is okay and hazard warning system operates turn signals, replace turn signal flasher. If turn signals still fail to operate, check steering column connector. If connector is okay, replace turn signal switch.
