The footwell blowers are behind the right and left footwell panels. If you get your head down near them you can clearly hear them running. Do the footwell blowers go off if you put the rotary switch on position 3? Make sure the fresh air fan is off (dash controls) so you don't confuse the sound.
If the footwell blowers go off on position 3 check the round relay on the front trunk relay panel (position 1, closest to the windshield). Switch the relay with another relay to check. Also check fuse #2 (counting from the rear of the front trunk fuse panel).
If the footwell blowers stay at the same speed on position 3 it might be the rotary switch, but it could be the above round relay with the contacts fused "on". The footwell blowers would be running at the high speed in this case. Switch the relay as described above to check.
