Default 06 Forester, "motorboat" noise in cabin

I posted a version of this initially in the Forester section, but had no response, so, here goes:

Yesterday morning, coldest day of the year, so far, started up and was presented with a "flapping" or "motor boat" sound. Or "stick in the bicycle spokes" sound.

06, manual trans, auto HVAC system.

I can add this noise is present with the key in "run" position and engine not running, but not in the "accessory" position.

The noise is "faster" once the engine is running (higher voltage) but does not vary noticeably with engine speed. The fan speed and vent controls all seem to work properly and do not change the frequency of the "beats".

I can feel thumps "in time" with the noise when touching the blower motor assembly behind the glove box area, but as I said, it does not change with fan speed, or when changing air distribution settings.

Clearly it is something "electrical" but no clue.
