Chrysler Repair: 2000 Concorde AC problem, concorde lxi, board diagnostics

Question
Hi Roland,
You've probably heard this one:
I've got a 2000 Concorde LXi with auto climate control. I had the compressor replaced last year when the clutch seized. This year, it was blowing hot air when I started it the first time. I've had the system purged, recharged, and checked for dye leaks (looks ok). What is the procedure to run the on-board diagnostics for this car? Any idea where to look for a fix?
Thanks,
Mike

Answer
Hi Mike,
With the engine running, the control set to 75>sno F, press and hold the three right push buttons at the same time.  The display will begin to blink, Release the buttons, the display will continue to blink, then after it runs its tests it will stop and display a two-digit fault code. If no codes, it will return to normal diaplay. After each code, press the panel push button for the next code if any. Write back with the trouble codes and we'll go from there.
