If the blinking rhythm on one side is faster than on the other, then one of the lamps on the "fast" side is out of order or the wire is broken.
In all other cases, the cause is in the flasher relay. To check, remove the relay and connect relay contacts 1 and 2 (pins located next to each other) to the battery using auxiliary wires. Then connect two incandescent turn signal lamps (21 W) connected in parallel to contacts 1 and 3; the lamps should flash at a frequency of 60 to 120 times per minute. If you connect only one lamp, the frequency will increase to more than 140 times per minute. Otherwise, replace the flasher.
If you do not have a new relay, insert a thin wire between contacts 2 and 3 in the relay connector.
Caution: Do not damage the sensitive relay contacts. Before inserting, bend the ends of the wire so that there are no sharp edges. Insert the defective relay again. The relay legs are so long that the relay can be inserted with a jumper.

Turn on the ignition. When you switch the turn signal switch, the turn signal lamps of the corresponding side are now constantly lit. By quickly switching the switch on and off, you can simulate the operation of the breaker. But at the first opportunity, you should replace the relay.
If the turn signals do not light up even with the jumper, the cause of the defect lies in the switch or in the wiring.
