Re: 2001 Intrepid SE Windows Fogging

Glenn,

I did exactly as you described and just as you said, the chime sounded,
the 
AC button started fla****ng and the odometer area on the dash display went
to 
"AC00".   The system then went through some motions and I could hear the 
exhaust switching through the different vents.  Within a minute or two the

"show" was all over, the "AC00" disappeared and the odometer mileage 
reappeared.  (There were no trouble codes displayed.)

I was not sure if I happened to miss a trouble code, so then re-ran the 
diagnostic a second time, this time watching the display, but again, no 
codes were displayed and it went directly back to the vehicle mileage.

Afterward, I re-checked to see if the blower speed and airflow changed
when 
I toggled between dash only and the recirculate function, but again, there

was no noticeable difference to my ears.

Does this procedure I just performed supercede the one you described 
previously?  Did this diagnostic perform the calibration that I should
have 
done after removing/replacing the battery in November or do I need to do 
that when the weather warms?

I will see tomorrow morning if there is any change on my drive to work. 
Thanks again for all you have done to assist me with this.  I really do 
appreciate the effort.

  Bob

PS Please say a prayer for the Northern Illinois University families (my 
middle son who will be getting the Intrepid is  currently in his 3rd year 
there) that have been affected by the horrific tragedy that took place on 
campus this afternoon.
