Hello there. 300SDL. I unplugged the key/seatbelt buzzer since it was driving me mad. Now I seem to have killed the door operated dome light. It there a way to get door operated dome light and not have that anoyying buzzer? I have yet to hook it back up to see it killed the dome light but other than unplug the alarm (I don't need it and it goes off at the most wrong times) I have made no changes to the car.

Thanks,

-Alex

If I recall correctly:
That buzzer is also for your light left on warning.

I do not recommend this, however at least one owner has done it.

There was one 300SDL roughly four year ago, the buzzer drove the owner nuts, he removed it, cracked the case open, broke the buzzer, and reinstalled it.
