Does anyone remeber how to put the Heater/AC head into the diagnostic mode. I did a search every way I know how, but can't find it. I remember seeing it here at one time.

Thanks

Turn Key on, Turn on Heater.. Then Press OFF and FLOOR at the same time, release then press AUTO.

Hmmm. My blower just blows cold air continuously after AUTO has been on for 15-20 minutes. I tried the key on, OFF/FLOOR followed by AUTOMATIC, but nothing happens. The temperature setting shows, and the fan comes on at low speed, but no cycling of dashes, no codes.
My warranty is running out soon; I've had it in to the dealer several times and they can't find a problem (probably because it takes 15-20 minutes to surface), so it would be nice if some problem codes showed up (I would hope that they would have checked for those, but you never know).
Any suggestions? Am I missing a step here?
Thanks.

Yeap, turn key to on position AND press OFF until you have NO display, touch off & floor and let go RIGHT away, press AUTOMATIC and release right away.
