Just measured current through a friend's fan on full speed and same as mine (approx 15/16 amps).
Trying to understand how the diverter/blend doors work. If I have my fan on full and test all vent positions and the recirc. button, they all work OK and divert air to the correct vents, The temp controls work OK, can adjust cold to hot on both sides of cabin. If there was a blockage in the system somewhere that is restricting the air, I would expect the fan speed ti increase if the blockage was removed. I removed the pollen filter and left the pollent filter chamber open, fan speed (and current draw) does not change, so wouldn't that indicate no blockage upstream in the system? The reduced airflow occurs from all vents (screen, face, floor).
Looking at the system diagram and the vent controller, I assume each vent (face, screen and footwell) has its own door/flap ? If yes, these are all working the same i.e. cant see a fault that would affect all flaps ? The reciirc. flap fully opens and closes. I've put an endoscope camera upstream from the pollen fiilter and no sign of any debris blocking the evaporator core,unfortunately can't get access to look at the heater core which is next upstream. After the heatwer core, the airflow is directed to the various vent flaps.
