We have had the 2004 S for about a month (my wife drives it - I don't). Anyway she said she got in the car to drive home from work and nothing on the dash related to heating and AC lit up when she started the car. She checked the manual which said it was supposed to be in "auto" mode. Anyway after pushing buttons i.e. AC with no result she drove home.
She parked the car and just for the heck of it started it again. Voila!!! Everything back on and operating. Aside from a short somewhere, anyone have a clue as to what might have happened?
