Answer
Codes:

1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons on your climate control panel for 3 seconds and release them.

2. Diagnostic codes will appear in the form of LETTER/NUMBER combinations such as E23 or E64 and then you might see EE23 or EE64.

3. The display will stop at .7.0

4. Write down EXACTLY what displays in the EXACT order in which they display and let me know what they are.

5. turn ignition OFF.
