Checking the sound and light signal (VW Golf 1)

Contents: Light signal ↓ Malfunctions in the horn device ↓

When the ignition is on and the horn contact is pressed, a horn should sound in the steering wheel. In a better equipped car, two-tone signals sound. In order to save contacts, a relay is connected in models with two-tone signals.

Remove the connector.

Insert sufficiently long wires into each connector and use them to connect the "+" and battery terminals of the battery.

If it is quiet, then the sound signal is defective.

If the signal is making a crackling sound or is completely silent, it can sometimes be repaired by turning the adjustment screw on the back of the signal.

Clean the screw from the sealing compound.

After adjustment, seal the screw again with sealant to protect it from moisture.

The horn has an adjustment screw (2) on the back under a plastic cover. Wire "1" goes from the horn contact to the relay; through cable "2" voltage is supplied to the sound signal.

Light signal

If the light signal does not function, although the headlights are on when the lighting is on:

Check if the red or red/yellow cable (terminal 30) leading to the toggle switch is live.

If yes, check if the light switch in the toggle switch works.
