    Alfa Romeo 147 2.0 2002 - Climate control not working, display not illuminated # Archived Message

    Posted by Glyn Morgan on May 5, 2009, 10:31 am

    Good morning

    ZAR93700005079294

    I had the above in with the climate control not working, the digital displays above the controls were not illuminated.

    Pleasantly suprised that AD had a wiring diagram for this system I checked all the fuses, all ok.

    Checked the climate system serially, no fault codes present/stored, live data correct and could actuate the switch leds and digital display. After that the display worked and nice cool air was being blown into my face . But when you turn ignition off then on it reverts to no display or operation.

    In the multi function unit there was one code that would reoccur, I am struggling to understand it.
    9029 lighter and A/C light signal above maxiumum threshold.

    Any ideas

    Regards Glyn
