Open driver side door and the buzzing noise begins and if you stand there long enough it changes sound and pitch, may stop momentarily, but continues. Close door, insert key, buzzing noise continues. Start and drive car; buzzing continues. Stop car, remove key buzzing continues. Exit car, close door, buzzing continues, eventually stops after an unknown period of time. Sound is coming from above instrument cluster area.

If this is what you're experiencing, there's no easy fix.

 

Thank you for the prompt reply..
Yessir, that’s the noise! And from what I’ve read, the only fix is pulling the instrument cluster and clipping a speaker wire? Is there a video somewhere that shows instrument cluster removal?

 

I experience a similar issue when my battery gets low enough to die soon. Modern cars' electrical parts get wonky with a low battery. Check your battery voltage, hopefully it's an easy fix....

 

About two weeks ago it experienced a “no crank” issue, second time since we bought the car in 2000. Removed and wire-brushed the battery terminals and she cranked right up. After reading your suggestion and checked battery voltage (12.6), removed and thoroughly cleaned terminals on battery and battery connection leads with wire brush; there was no corrosion on either. Reconnected all and connected back to battery charger/maintainer, which it stays on to keep fully charged. Noticed charge rate was 70% on charger, which I thought was unusual, so I stood there and watched it to make sure it was charging and kept opening and closing the driver side door to observe buzzing sound as battery rate climbed between 70 and 100% (full charge). At 75% I opened the door and there was no buzzing so I thought that maybe the battery had a problem and wasn’t fully charging. This happened twice and unfortunately, the next time I opened the door (battery charged to 80%) the buzzing continued, all the way to a full charge. It is an older battery but appears to be in good shape; starts the car with no problem.

I’m getting very close to attempting to pull the gauge cluster and clipping that speaker wire.

 

Does anyone know of a video, or a written procedure somewhere, that shows/describes the removal of the instrument cluster of a C5 with HUD?

 

Why don't you just type "c5 corvette gauge cluster removal" in one of the numerous search engines. Took me all of 30 seconds to do this in Google and several u-tube videos and other written instructions popped right up.

 

Update:
Speaker wire behind instrument wire cut, noise eliminated.

 

Only thing now you don't have the chime. No warning when you leave fog lights on and so forth...
My friend bought an instrument cluster off ebay when his started buzzing. Think he paid about $100. Odometer reading goes with the IC
so he wound up with fewer miles on his 2002.
