I did the cut wire 7 years ago and have not had any negative results since. I have learned to live without the chime and rather enjoy not having it there.

Another GM engineering brain fart... why the hell would you bury some, obnoxious buzzer deep in the dash behind the IPC... at least put it somewhere that you can get to it to KILL it! On second thought maybe they did that on purpose so you couldn't access it easily and disable it...
it's just a loose loose scenario.

I will tell u EXACTLY what that noise is, mine did the same thing. Inside the instrument cluster there is a speaker for the key in ignition chime. The speaker is soldered to the board. I opened up the cluster and cut the wire to the speaker. It was the most annoying sound you would want to hear coming from your car.

Great info for the problem. Did you have to remove the instrument cluster to get to the area where you could opened it up? Was the wire you cut funneled through the instrument panal so it could be cut without opening up the cluster? Sorry for the questions but I am preparing for the eventual workaround.

Yeah, I agree with Bandit 00C5. As I remember from last summer, I pulled the IPC out and was able to crack open that speaker housing on the rear of the IPC enough to slip in and snip the wire. Problem solved. I don't miss the key chime either.

[QUOTE=LoneStarFRC;1589543735]After removal and some of the dis-assembly steps of the IPC. Personally, if I were going to enough time and effort to access the speaker, I would definitely remove it (2 screws and desolder two leads) and replace it. At that point it's not hard to do at all.

Nah, Sam deserves all the credit he gets for helping folks. 
I've putzed around with several diferent IPCs over the last few years, so I knew right where this particular speaker is located.
I'm just curious as whether or not it's actually a speaker problem, or the driver circuit/amp that sends it it's signal.

Well , the problem is that it's buzzing when It's not supposed to ! Like when the car is just setting there with no one in it. Cutting the speaker wire shut's it up and removes the annoyance, but .... I'd like to know the reason.

The sound is not from the speaker but a result of something being driven from the board. From what we summized replacing the speaker would not solve the problem.

Let me rephrase.....the sound is not a result of a bad speaker but it is transmitting something that is being induced by the board. The speaker is only delivering whatever is wrong with the board.

Noise from dash
I had the exact same problem. I took my car to my dealer and asked them to remove the instrument cluster and open it up to cut the wire to the speaker. They would not cut the wire. They did chase it to a bad cluster sending a bad signal to the speaker. I ended up paying $850 to get the cluster replaced. New cluster works like it should with no unwanted noise. The dealer won't cut the wire because of being liable for whatever is really wrong with the cluster. They were worried that something might burn up and I would hold them responsible for it. I understand their position. I didn't like it, since it ended up costing me so much, but life sucks sometimes.

I have dealt with this several times here on the Forum. Each time it required the IPC be fixed or replaced. Cutting the speaker wire will stop it also.
Here is where the speaker is. If you want to assess the IPC I am providing that also.

I am in the process of removing the speaker and I have the IPC loose from the dash, but I can't get the instrument wire cluster or the HUD cluster to release from the IPC. I can get my fingers to them, but I can't pull them free. Any advice for me? Thanks!

I didn't have HUD on my C5, so I didn't have to deal with that. But I don't remember having a problem removing the wire cluster from the IPC so I can't help you with that.
Interesting point about the speaker. I just assumed that the speaker itself was the problem, so I just clipped the power wire to it. Problem solved, but of course no key-in-ignition audio alert after that. :-(
