Electrical draw
I have a 98 Vette that is giving me headaches with an electricaal problem. It start awhile ago shortly after I had an aftermarkaet radio installed. I noticed that after driving the car and parking there was a buzzer sounding off on the passenger side of the car. I took the vette back to the company that put the radio in and they said "Everything was checked and the install was correct. The car continues to kill my battery and nobody has been of any help at all.. I have thoughts of tearing apart the dash and removing whatever they did at install. Any help would be greatly appreciated.

Did the installers hear the buzzing sound you described? Some thoughts. Make sure the Instrument Panel Brightness **** has not been turned all the way clockwise. The new radio was hot wired to be on all the time even with key off and the radio has a power draw.

Behind the toe board in the passenger footwell area is a fuse block with fuses and relays, you have to find out what is buzzing and killing your battery, look there before taking your dash apart.

Check the following thread especially post #15.
It could be the radio installation but the procedure in #15 will tell.
In my case, a battery drain suddenly appeared when the driver side seat switch failed. Pulling the seat circuit breakers stopped the drain, replacing the driver side switch fixed the problem.

Make sure that under the OBD2 port that the stereo installer did not PIGTAIL a lead onto the PURPLE wire This is an easy way to hook up an aftermarket system but not the correct way
It will cause communication issues with your ECM and a possible power draw
ALSO another common draw on a 97-99 C5 is the electric seat adjuster---When failing it will draw power all the time As a test unplug the pigtails under the seat and see if that helps
( this was the issue with my 98 power draw)
