Remove dinger chime bell buzzer
I removed the dinger speaker altogether. The problem was that the speaker on my 2001 was attached to a computer type card. Maybe this speaker location is something new. I never found the speaker in the locations mentioned in other TDR post.
Again, this removes the entire speaker. So if you still want to hear the buzzer for not wearing the seatbelt, low fuel, etc. , don't do this. The other suggestions in this post are if you just want to kill the door dinger noise only.
Anyway, here's what I had to do if you want to try it. It's been a couple months but I think I can remember...
First take the knee panel off the dash underneath the steering wheel. I think the knee panel is held on by three or four screws. After I removed the knee panel I could see a black plastic box about 5x7x1 that had two wire harnesses going to it. The box was held in by just one screw.
Take the screw out and unbutton the two wire harnesses and slide the box out.
If I remember correctly the box was held shut by four screws. Once the screws are removed the box will open like a book, revealing the computer board I mentioned above. This computer card, or board, is about the same size and look as a modem card that would go in a Personal Computer.
BE CAREFUL! You should only touch the outer edges of the green card that's inside the black box. Keep your 15W-40 diesel fingers off the tiny wires and components that are all over the card. Once you open the black box you'll immediately see the round black speaker. It's about the size of eight quarters stacked up, and it has little holes in the top of it.
To remove the speaker you have to take the card out of the black box first. The card is mounted in the black box by three or four screws. Once the card is out flip it over and you'll see where the speaker is soldered to two points on the card. I took my soldering gun and touched each spot to melt the solder (whatever you call that stuff). The speaker will practically fall off when you melt the two solder points.
Now put everything back. Now everything works the same as before. Just no noise, ever.
I hope I didn't make this procedure sound difficult because it's very easy. I just wanted to cover my back-side for all you greasy dudes that have never handled computer cards.
So, just be gentle with that computer card.
DON'T rip the speaker off the board like a gorilla - you might break other components!
Don't let static electricity get to card. Handle it on the outer edges and you'll be fine.
You may not use a cigarette lighter to melt the solder points on the card.
Putting duck tape over the speaker won't lower the sound that much at all - I already tried.
If you ever want to put the speaker back just solder it back on.
