Troubleshooting audio signals (VAZ-21011)

The reasons for malfunctions of sound signals may be the following: the switch does not work or is stuck, the sound signal or signal switching relay is damaged.

To detect a malfunction, check the reliability of the wire connection, the condition of the switch and relay contacts. Clean the contacts if necessary. Replace the faulty horn, switch or relay with new ones.

If the signal volume decreases or wheezing appears, check whether the battery voltage is low. If it is normal, adjust the signal by turning the screw on its body in one direction or another until you get a loud and clear sound.

If the adjustment does not eliminate the wheezing or the signal works intermittently, then disassemble the signal and clean the contacts of its interrupter.

When assembling the signal, it is necessary to install the previous gasket between the membrane and the signal body so as not to disturb the gap between the core and the anchor.
