    I didn't know this, so thought I would share it Air Con diagnostic Modelove car

    For R32 and R33...

    Climate Control Diagnostics R32 and R33

    The climate control has a diagnostic mode.

    Enter the diagnostic mode by pressing the OFF button for five seconds within ten seconds of turning the ignition on.


    Sensor check
    Sensor check is selected by pressing HOT switch (the red triangle) while in diagnostic mode. The microcomputer detects whether each sensor input signal is within correct parameters. The results are displayed on the screen.

    If normal, a "20" is displayed.

    If abnormal the failed sensor number is displayed. The sensor numbers are as follows:

    20 - all is normal


    21 - outside air sensor
    22 - Inside air sensor
    23 - Water temperature sensor
    24 - Intake temperature sensor
    25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)
    26 - PBR
    27 - Refrigerant temperature sensor

    Although on Gordons one it has this extra bit

    (This is probably not the cause of your problems but it is a nifty self check to play with).


    While in Sensor check, depress the HOT button again. This will operate the the mode door actuator, and checks the whether the position detection switch is operating. Again the results are displayed on the display.
    If normal, a "30" is displayed.
    If abnormal the number of the faulty mode is displayed as follows:
    30: Normal
    31: VENT
    32: B/L (Bi level)
    34: FOOT
    35: DEFROST/FOOT
    36: DEFROST

    If I press the hot again, I get a number starting with 4, is that to check the fans ?
