Answer
OK.

1. Turn the ignition switch to the ON position, Do NOT start the engine.

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

3. You will see A LETTER and NUMBERS appear on the screen and the screen will stop at .7.0

4. If you see "E" codes, Simultaneously push and hold the OFF and HI
buttons on the display and you will see E.0.0 and then release the buttons.

5. If you see "F" codes, Simultaneously push and hold the OFF and LO
buttons on the display and you will see F.0.0 and then release the buttons.

6. Turn ignition OFF.


7. Repeat steps 1 thru 3 and see if any codes appear exactly as if you were video taping the display and let me know what they are.
