Hey gang - I've looked around, but I have not seen specific instruction for getting into the DIC information (stored codes, etc) on a 2002 Deville. The usual instructions for "OFF & Warmer button" don't seem to apply, as the "OFF button" is also the "warmer" button - at least on my dash...I tried holding down the round "OFF/Warmer" button and the PASS TEMP button, but to no avail. All that did was turn the system on or off.

Appreciate any thoughts....

Hold Down the On/Off Button and the up arrow button on the information center. That should get it to come into the DIC mode. then just play around with it and you will get the hang of it. That is what I did and it works pretty good.

Got it. I was using the heater on/off button, instead of the three other ones... duh...
