Using the self dianostic for the A/C

How to Retrieve a DTC
The audio-HVAC display panel has a self-diagnostic function for heating, ventilation, and air conditioning system. To run the self-diagnostic function, do the following:

Turn the ignition switch OFF.

Turn the fan switch OFF.

Set the temperature control dial on Max Cool, then push the mode control button to select Vent.

Turn the ignition switch ON (II).

Press and hold the recirculation control button.

While holding the button down, press the rear window defogger button five times within 10 seconds. The recirculation indicator blinks two times, then the self-diagnostic will begin.

If there is any problem in the system after self-diagnostic is finished, the recirculation indicator will blink Diagnostic Trouble Code (DTC) 1 through 6. If there are any problems in the evaporator temperature sensor circuit, the A/C indicator will blink DTC 7 or 8.

If no DTC's are found, the indicator will not blink.


Cancelling the Self-diagnostic Function
Turn the ignition switch OFF to cancel the self-diagnostic function. After completing repair work, run the self-diagnostic function again to make sure that there are no other malfunctions.

Max Cool Position Function
When the mode control button is in the MAX COOL position, the audio-HVAC display panel will automatically select the recirculation mode and turn the A/C on. The recirculation switch and A/C switch are disabled and cannot be turned off in this mode. If the audio-HVAC display panel fails to function as described, replace it.

Hey Princess, I did that exact procedure and what happened to Epsomax happened to me, check engine light blinked 5 times, but sometimes all of the lights of the A/C, as if everything was ON, started to blink except for the bottom line of the second '8' of the first pair of temperatures. My actual problem is that the fan blower is not working. Everything was working fine and then air stopped flowing though vents.

Anyone know what the Diagnostic Trouble Code (DTC) 1 through 6 for the recirculation indicator are?
