Turn signal flasher — check (Opel Omega B2)

The intermittent, flashing light of the front and rear lights when the vehicle turns and the intermittent light of the hazard warning lights are created by the electromagnetic turn signal relay-interrupter.

Examination

If the rhythm of the turn signal light interruption on one side of the car has a higher frequency than on the other, then the cause is a burnt-out bulb or a broken wire on that side.

If the bulb is in good condition, then in this case the first thing to check is the turn signal fuse.

If the hazard warning lights do not work, but the direction indicator functions properly, then, as a rule, there is no power supplied to terminal 30, to which the hazard warning light switch is closed.

If the situation is the opposite, i.e. the hazard warning lights are working but the turn signals are not turned on, then, as a rule, there is no voltage supplied to terminal 15 of the breaker, to which the turn signal switch is connected.

If the cause of the malfunction cannot be determined, then the hazard warning light switch, which has a built-in relay, should be replaced.
