I really like the new (to me) C6 but the turn signal sound (tic tic tic)
is so low it is just about useless. Its there something like an old
fashion flasher relay that can be changed to increase the sound level of
the tic tic tic. It is swamped out by the engine and dual mode exhaust.
Are the all low or is low tic tic tic sound mean something is wrong with

As you were told before, there is no flasher relay. The turn signals
as well as almost everything else on the car is computer controlled.
The BCM (Body Control Module) decides when and how fast to flash the
lights and sends a signal across the data bus to the radio to make the
sounds. (The ECM (Engine Control Module) has nothing to do with this.)
Instead of worrying about the sound, just learn how the car was
designed to be used. The sound in your father's Oldsmobile was there
to remind him that the turn signal had been on for the past 10 miles.
The C6 will remind you with a chime and message on the DIC if you
forget for 30 seconds.
There are literally thousands of things done by the computers in this
car that used to be done mechanically. Computer control is better but
that also means that you shouldn't just go cutting and sparking wires
like you could in a mechanical car. Instead of just blowing a 10 cent
fuse you are likely to blow a several hundred dollar computer. If you
insist on modifying this car the first thing that is mandatory is a
set of shop manuals so that you can figure out which data bus has the
digital signal you need. See helminc.com
My manual states that the turn signal flasher is integrated into the
hazard warning switch on center dash. On page 8-453 it says to see
page 8-451 for replacement instructions of that switch. Then on page
8-278 the instrument panel schematics it shows an ICP named "Turn
Signal Audible Indicator" as part of the Instrument Cluster ICP. A bit
confusing but my money goes with Steve's information since my manual
is an early ('05) manual with information cut off date 04/11/2005 that
still has C5 illustrations.
