Why does the turn signal not sound after replacing the battery in the Regal?
2 Answers
After replacing the battery in the Regal, the turn signal not sounding may be caused by poor line contact or a faulty buzzer. It is recommended to check the wiring at an auto repair shop. Introduction to turn signals: Turn signals are important indicator lights that are turned on when a motor vehicle is turning to alert vehicles and pedestrians in front, behind, left, and right. The importance of car turn signals: The signal indicates that the vehicle will make a turn or overtaking operation, reminding the following or oncoming vehicles to pay attention. The prototype of modern car turn signals can be traced back to a certain model of Buick cars in the 1940s, which had them installed at the rear.
I've seen many cases where the turn signal sound disappears after battery replacement, usually due to a blown fuse or loose wiring. During battery replacement, it's easy to accidentally loosen the fuse box under the dashboard - there's a specific small fuse for the turn signal sound that often causes issues. Check the turn signal section in the fuse box and try firmly inserting a 10A or 15A fuse. If that doesn't work, the turn signal buzzer might be stuck; it's located behind the dashboard - you might need to open it up and replace it. If the problem persists, it could be a circuit module reset issue - after battery replacement, the car needs time to relearn its settings, so try driving for a while to see if it recovers. Regular checks of these details can prevent many headaches. If you can't fix it yourself, it's safer to visit a repair shop to avoid compromising driving safety.
