Annoying Convenience Center Chime
The convenience center chime comes on with the ignition on and the car running all of a sudden and wont stop until you turn the key to off.
I found this info from this thread:

I am not really that great with wiring, so I dont know what I should be doing with my multimeter. I pulled out the little module from the convenience center stop it but I want to fix it so I dont leave my headlights on and kill the battery one day.
The only thing I messed with recently was the instrument cluster. I pulled it to replace the turn signal bulbs and the SES light bulb. The only bulb that i could see thats not illuminating is the Brake light, and I should have checked it before putting everything back together.

My 85 Camaro shop manual has a section on the Audio Alarm System (Sport Coupe), located in the convenience center.
Buzzer alarm: Constant pitch buzz, all conditions
Chime alarm: Fast pulsed chime, lights-on
Fast chime, key warning
Slow chime, seatbelt warning
Circuit Operation
Lights-on Warning
This circuit needs voltage through the INST FUSE, STOP HAZ FUSE, and the GAGES FUSE to operate properly. When the LIGHT SWITCH is in "Head" or "Park," voltage is applied through the INST FUSE to the solid state AUDIO ALARM ASSEMBLY. When the ignition switch is in "Run," "Bulb Test," or "Start," voltage is applied through the GAGES FUSE to the solid state AUDIO ALARM ASSEMBLY. These two voltages are sensed by the solid state unit and the Lights-On Warning is not sounded.
When the IGNITION SWITCH is turned to "Off," the GAGES FUSE loses voltage, and the solid state unit senses the change. If voltage is still available from the INST FUSE, current flows to sound the alarm. This current grounds at G200. The alarm can be turned off by turning the Light Switch to "Off." The AUDIO ALARM ASSEMBLY no longer senses the voltage from the LIGHT SWITCH, so the alarm does not sound.
TEST LIGHTS-ON WARNING
1. Turn LIGHT SWITCH to "Park" and I/P LIGHTS to "Bright."
2. GRY wire at FUSE BLOCK: 12 volts.
3. Turn LIGHT SWITCH TO "Off."
4. GRY wire at FUSE BLOCK: 0 volts.
5. Turn IGNITION SWITCH to "Off."
6. Chime does not sound.
7. Turn LIGHT SWITCH to "Park" and I/P LIGHTS to "Bright."
8. Chime sounds fast-pulse tone.
9. Turn LIGHT SWITCH TO "Off."
10. Chime does not sound.

The beeper (aka door chime module) is plugged into the convenience center above the pedals, toward the center of the vehicle. You can unplug it and check the signals on all the inputs for the module to see which one is causing the chime to come on.

Hope this helps.

Re: Annoying Convenience Center Chime
Why not just unplug it - it's about the size of a pack of smokes, under driver dash, has what looks like speaker holes/slots in it. It simply unplugs from a socket like a flasher or something.
