Just in time, after the provisorily repair of the rear brakes, the new blower motor arrived and I started with the task to get the old one out.

Our American collegues discussed and reported several methods to do this.
Their methods have two things in common, namely
....(1)...to take out the "False Firewall" (FFW), which separates the A/C & Heating system from the engine
....(2)...to remove the windscreen wiper assembly incl. motor
Both actions are intended to provide more working space.
"Alfisto Steve" wrote a procedure for the FFW-takeout, which consists of 23 steps

I do not know for which engine he wrote that. It could not be the 3Liter 231 horsepower beast of the Q's.
I expected a nightmare and was finished in about 20 minutes.
- On the bottom edge the Q4 FFW has several clamps, which sit on a rim ("Kante"), no screws.
- On the top edge there are 4 screws, one on each corner and two in the middle, holding a smal strut towards the wiper assembly (red arrow "
A").
- Next item is the big round connector (blue arrow "
B1"), which must be disconnected and the long end pulled out of the FFW through the hole (blue arrow "
B2").
The adjacent fuse is unscrewed from the FFW.
- The third item are two clamps which hold two hoses to the FFW (green arrow "
C"), better seen in the left picture below.
- Finally the 12V lead-through, which also acts as fixture for two 40A-fuses for the water cooling fan (yellow arrow "D1") and for the blower motor (yellow arrow "D2") has to be taken off.

Now, with the help of two additional hands the FWW can be wriggled out of the clamp seats.
Just don't claim anymore, that everything on a Q4 is more complex and cumbersome!!
- The removal of the windscreen wiper assembly is done exactly as Steve explains it in his write-up quoted above.
Also this task is fairly simple and straightforward and does not take more than 20 minutes.
And there it is, the housing which harbours the culprit.
How to get the motor out I will discuss in the next posting.
