THESE, are all trouble codes with the Climate control system. To get into troubleshoot mode, you have to :
1)Turn ignition switch ON
2) Hold the OFF button on the Climate Control Panel
3) *WHILE HOLDING THE OFF BUTTON*: Press the "Recirculation" button 5 times within 10 seconds.
4)This should begin the diagnostic,and the temperature settings will light up determining if there is something wrong: (see attached pictures).
5)Depending on the section lit up, there's a letter assigned to each section, so using the list below,you can determine what is wrong.
