Blower

I've noticed today the blower seems to send air to the footwell all the time ie if I select face vent it moves to the face vent and blows out the face vent leaving the footwell but footwell seems to still get some blow same with the screen setting too which shuts off face and moves to screen but blow at footwell!! No book symbol and air con and heater works ok left and right hot cold etc. Had new servos done 6 mtg ago . Could it be a calibration of flaps is required using autologic or say leakage of air from seals on distribution flap or just me being fussy should I live with it lol! Btw p38 4.0 se 1997

Had the flaps calibrated today using autologic and there is slight improvement however it does still blow from footwell when face or screen vents are selected. It must be an anomily of that particular heater box so as it works ok ish I will leave it as is unless someone has any suggestions.
