Where is the turn signal relay located in a Toyota Corolla?

[StFaith]

Corolla turn signal flasher relay is located in the fuse box in the front engine compartment. Turn signals are important indicator lights that activate when a motor vehicle is turning to alert surrounding vehicles and pedestrians. The turn signal bulbs use xenon tubes and are controlled by a microcontroller circuit, working continuously with alternating left-right flashing. Below are the reasons for turn signal failure: 1. If turn signals don't work but hazard lights do, the turn signal switch may be partially damaged; 2. If individual turn signals don't work, the bulb may be burnt out and needs replacement; 3. If all turn signals don't work, the turn signal fuse may be blown, causing complete failure.
