Dual Zone Climate Control
On my Grand Prix GTP, dual zone climate control, there is a way to enter "diagnostic mode" by pressing the driver and passenger control ***** at the same time and holding until the display reads 00.
After the display reads 00, I turn the drivers **** to display a number corresponding to a code (I have a chart showing the codes and discriptions) and then turn the passenger **** one click to activate the code number selected.
For example: most of the modes available check various functions of the heat/ac system but a few are kind of cool to check.
The default 00 display, when activated, shows stored trouble codes for the system.
Choose 12 in the display and it reads out coolant temp.
Choose 13 in the display and it reads out digital speed in mph. (this is fun for passengers to watch)
I was curious if the C5 dual zone had this feature and if anyone had the list of modes and trouble codes?

Re: Dual Zone Climate Control (2k2C5)
The DIC ( drivers information center ) should do most of these functions. Never tried this with the dual zone but I wouldn't think it would work as it did on the GP.
