Guys, need help!
How should I remove air ducts? From top or bottom ? I already popped it off and have some movement but it seems there's not enough space

Other members in this forum claimed that they could remove this air duct without taking center arm console off. I tried but not as clever as them. I could not take this air duct out in order to get to the fan motor. I ended up following the instruction from a British member who took out center arm console and remove this air duct.
When you look at the bottom of this air duct, it joins to another long flat duct which runs under the center arm console to provide hot/cold air to the rear vents of the center arm console and to the small compartment within the arm console.
Once you remove this air duct, you will face 2 more side air ducts on each side of center console. Members here could remove those 2 side air ducts without taking the driver side steering cover and passenger side glove box off. I tried but no luck especially when you try to put these 2 side air ducts back, both panels off. You need room to push these 2 air ducts back in place.
Good luck.

Am wondering if you - anyone? - has got any specific diagnostic tips on testing the fan/resistor combination independently of the rest of the system? EG, what is the minimum componentry required to operate/test the system? Should the fan run with only the Climate Control Dashboard Unit installed? Does anybody have the input schematic of the Speed Control/Resistor Unit "hedgehog"? Though Speed Control/Resistor Unit on my E60 doesn't have this resistor radiator 'hedgehog' appearance...
I'm relying on your authority that the 'hedgehog' doesn't often go bad. I've recently replaced only my blower fan, but left the original speed control in place. IN my case, system was working perfectly, including fan speed control. But fan had developed the dreaded bearings-worn-out-squeal.

about to do our first tests with INPA - only recently installed. So was hoping for something a bit more... fundamental. IE, pre-INPA (!)

Now get in an E39 and you can test all day without INPA or ISTA

I may get to playing with INPA in about a week; meanwhile... ???
As long as we're on the topic of (re-)programming the car: Would it seem reasonable that the blower motor would be completely non-functional after the battery has been disconnected for an extended time - as it was during this project...?
Other aspects of the HVAC system seem to be working - IE, various actuators, etc. seem to be 'clicking' behind the dashboard as I cycle though various controls.
Ah; edit: Found this, which may go some way toward answering some questions:

Yeah the pic posted is a good start.
No the battery being disconnected for long periods has no bearing. I've had my battery out for a whole month and had no issue when putting it back in.

That guide is excellent! Just replaced the blower motor on mine this weekend. Took about 4 hours.
I didn't remove the center console completely, but just undid the bolts and nuts so I could pull it towards the rear a few inches which allowed me to get enough clearance to remove the center air duct.
The left and right ducts could be removed without removing the driver's and passenger's foot panels, but to get them back in, I did remove them so I could get my hand in and clip them in place. No need to remove the glovebox though.
