* Turn signal switch: The turn signal switch is responsible for sending the signal to the blinker bulbs to turn on and off. If the switch is faulty or damaged, it can cause the blinkers to not work properly.
* Wiring: The wiring for the blinkers may be damaged or corroded, preventing the power from reaching the bulbs. Check the wiring for any breaks or shorts, and repair or replace as necessary.
* Relay: The blinker relay is responsible for controlling the flashing of the blinker bulbs. If the relay is faulty, it can cause the blinkers to not work properly. Check the relay and replace it if necessary.
* Hazard switch: The hazard switch is used to turn on the blinkers simultaneously. If the hazard switch is faulty or damaged, it can affect the operation of the blinkers. Check the hazard switch and replace it if necessary.
If you have checked all of these things and the blinkers are still not working properly, you may need to take your vehicle to a qualified mechanic for further diagnosis and repair.
