L322 cabin temp sensor?

[RR P38]

When you open your door (key out of ignition) can you hear your cabin temp sensor fan running, in your HECAV control centre.
Its not that I can hear it so much as........what is it doing on!
Normal-Abnormal???

Normal. No idea why though. Maybe it's just excited you're about to go for a drive. :-)

Yeah, normal. All sorts of stuff runs on these when you think they shouldn't be...:D. Probably one of the reasons they chew through batteries.
