    Astra H - Location of Climate Control ECU

    Astra H - Location of Climate Control ECU

    My interior blower fan is not working.
    It's not the actual fan, it moves freely, and work given 12v direct.

    I tried to diagnose problem with Opcom, and it mentioned Climate Control ECU failure.
    I thought maybe the ECU may be part of the three dials switch unit, but nope, after trying two of those.

    Where is it ?
    Any ideas ?

    Thanks

      You should focus more on the speed controller of the fan.

      What else then, there is nothing else between climate control panel and this controller. Maybe a blown fuse.

      Just an update to this - I believe its fixed.

      The heater blower resistor that I replaced in the first place was duff. Bought a new one and its all working again.

      I was going round in circles as you don't expect a new part to be broken, lessons learned though.

      Thanks all for reading and I hope this helps others.

      That resistor should be at least 128c some of them below that value, melting off often
