    In digital positioning terms, 255 is fully opposite to 0 so that particular flap is either fully open or fully closed (or should be). If it bypasses the heater matrix you would have to force the AC into heat mode to get anything other than 255 out of it. Oo it's lovely and warm outside, too!

    Roger, that would explain the fault code. I'm glad I didn't dismantle the entire dash just to find the motor wasn't there.
    Paul, the 255 reading is probably because the feedback circuit is disconnected.

    Ah right I didn't realise that was the missing one. Dash out would've been a heartbreaker!
