The manual states that to troubleshoot the A/C pressure switch and thermal protector, I need to perform the following:

1. Turn the ignition switch ON
2. Press the AUTO button, then press the A/C button and check the display.
Does the display indicate A/C ON?
YES: Go to step 3.
NO: Check for loose or poor connection on the climate control unit...

On my car, pressing the A/C button after pressing AUTO, display shows A/C OFF.

Can anyone confirm if they are getting the same results on their car and the manual eff'd up? Or your display shows A/C ON after pressing AUTO?

 

Try holding the auto button down while pressing the AC button.

Alternatively, try the attached procedure.

good luck
