When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Some customers may comment that they are confused on how to operate the A/C system on vehicles equipped with dual zone automatic climate control (RPO CJ2). On 2003 models, a snowflake with a slash through it is shown on the display when the A/C has been turned OFF by pressing the A/C button. The A/C can be turned ON by pressing the AUTO button or pressing the A/C button again to remove the indicator from the display. For the 2004 models, the indicator will change to a snowflake without a slash and it will be illuminated whenever the A/C compressor is activated.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
