Blower running continuously

[red griff roger]

My 360 HVAC fan (not the rad fans) has just started running non-stop, even with ignition off and keys out. I have tried taking out the fuses, and that has no effect. The electrics are isolated now (this works), but would like to find a fix. Ferrari Chat has a thread (for a 430) with a number of suggestions, and I have tried most of those. The last idea was replacing the blower regulator 64280200, which I am waiting for. Any other suggestions out there?

Thanks, roger

Thanks all. Replaced the above part and fixed the problem. PITA to get at though. Just in case anyone has the same issue.
