In street traffic, drivers have long used a common, understandable "language": when turning or changing lanes, they press the turn signal switch; if they want to slow down or stop the car, red lights at the back signal this; and if the driver wants to warn someone, a sound signal will sound or the headlights will flash briefly.
Direction indicators
The direction indicators must be in good working order at all times, so the corresponding switch is supplied with power directly from the positive terminal of the battery via a fuse.
With the ignition off, press the red switch.
All four flashing indicator lights and the red window in the switch light up in the same rhythm.
If you now turn on the ignition, the green indicator light also blinks out of phase. See section "Direction indicator control".
Turn off the hazard warning system; leave the ignition on.
When the turn signal lever is pressed, the flashing signal and the green indicator light should flash regularly.
Malfunctions of direction indicators
[The original information is posted on the website: vwmanual]
If only the green indicator light flashes briefly once when the turn signals are on, then one of the lamps has failed. When the hazard warning lights are flashing, the failure of any lamp cannot be noticed. For information on replacing lamps, see the section "Replacing lamps", chapter "Lighting".
If the bulbs glow for a long time when the turn signals are on, the relay is defective. See section "Relays and control devices", chapter "Devices".
If only the indicator light is on, but the turn signals are not on, then the fault is also in the relay.
If the flashing indicators light up in turns: first at a slow pace, then at a fast pace (for example, when switching on or off high-power current consumers such as the heated rear window or windscreen wiper), first, move the wires located near the relay away from it. If this does not help and all the plug connections, including the rear light ground, are OK, the relay should be replaced.
If only the hazard warning lights work without the turn signal, there is no power supply to the corresponding fuse or there may be a defect in the switch (for dismantling, see chapter "Devices").
Short-circuit the faulty flashing light relay
Further driving with a faulty flashing signal relay is not entirely safe, since in heavy traffic and, above all, in the dark, other drivers will not notice when you want to turn.
The flasher relay must be pulled out of the neutral part of the electrical equipment. The relay is located in different places in models manufactured before July 1982 and after 1983. (see pictures).
Make a shunt bridge between terminals 49 and 49a. To do this, insert a paper clip or a short piece of wire into the plug connections of the central part of the electrical equipment.
Reinsert the relay.
When the turn signal lever is pressed, the lamps will light but will not flash.
When the lever is turned on and off, a flashing alarm rhythm is produced.
