QUESTION: How do I enter diagnostic mode for my A/C and how to get digital readout of various engines parameters and settings?
To enter diagnostic mode, push and hold the fan up arrow and down arrow at the same time until the LCD shows -00. You are now in diagnostic mode and may select any parameter using the up and down arrows. To see the value for that parameter, press the fan "auto" button.
