  Q: What are the functions and locations of turn signal lights, and how can they be diagnosed and replaced on Mazda 323?

  A:

  Flashing of turn signals and hazard flashers is done by the turn signal/hazard flasher which is a small canister type in shape found on the driver side of the fuse box under the dashboard. It is fitted on a bracket with the Horn relay, TNS relay, Headlight relay and Wiper relay in older models, but in the more recent models, it is located behind the lower dashboard panel under the steering wheel and has to be removed by removing the left side panel, the lower panel screws, and a push fastener. The flasher unit makes a clicking sound when it is operating correctly; when the turn signals do not work on one side and the clicking sound is not heard, it is probable that the turn signal bulb is defective. To test the flasher relay, make the ignition on and use the turn signal switch to make sure that the front and rear signals flash and operate the Hazard warning switch to make sure the front and rear signals flash too. In case neither of the two turn signals flash, possible causes are a faulty flasher unit, a broken bulb, a faulty switch, or a loose/open electrical connection; a blown fuse indicates that there may be wiring shorts that need to be checked before replacing the fuse. To change the flasher, loosen it by removing it out of its mounting bracket and loosen it by pulling it out of the electrical connector. In case, there is a suspicion on a faulty flasher, the same can be tested by a dealer or qualified shop and in case of defective units, the same has to be replaced as a single unit and the replacement unit should be identical to the original. When only one of the sides is not blinking, proceed to examine the possibility of burnt out bulbs, and installation is in the opposite order of the removal.
