Answer
OK, We need to look for fault codes in the computer and clear them.

Follow these directives:

1. Ignition ON, Engine OFF.

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

3. Write down any LETTER/NUMBER combinations that appear on the display until it stops and reads PCM?

4. Let me know what the codes are.
