On many cars one bulb on one side will cause both front and rear turn signals not to work so 1st check bulbs. Hope it fixes.
A dead battery
A blown fuse or a damaged computer would cause the turn signals, interior lights, and door locks not to work in the Mazda 3. The fuses are located under the dash on the driver's side of the car.
Usually, a fast blinking turn signal means one of the outside turn signals (front, back and side) lights is burned out.
cause they are sick nasty
Flasher is faulty.
Most common cause of the turn signals not flashing is a defective flasher relay. Replace it.
if only the turn signals are not working,you should replace the flasher can
If it is only one of the passenger side turn signals, it has either a shorted power lead or an open ground; check the ground first. If both front and rear turn signals are not working, check/replace blinker module.
Yes. The relay that controls the turn signals is built in the switch.
Yhese are fed from different sorces so I would check the groiunds on the lights.
