First time posting. Car had the lights left on last night, went out to it this morning, and was buzzing from the left front. Opened the door with the key, light swx was on, so opened the trunk and put a charger on the battery. Buzzing from left front now got very loud, and did not stop. Cycled the locks, started and drove the car, buzzing did not stop. Pulled some sort of speaker buzzer from under left headlamps, even with the electrical connector pulled, some sort of capacitor kept this thing buzzing. Sent my girl to work in the car, only other symptom is radio is dead. Did NOT hook charger up incorrectly. What is this buzzer and its role in the car? What should I expect if I reconnect this device? Any insight is appreciated.
Thank you,
Garth
