Hi Friends, I'm sure you are still looking for a solution to this! It's hard sometimes isn't it! As for the issue to the rear vents not blowing strongly (or a small amount of air on high) there is a flap imbedded in the centre console. see image attached. The open/close dial stops working and thus the open setting fails and remains closed. In order to rectify, get a flat blade and manually open the flap; have the air going so you can be aided by the airflow, and so you will know that it is open. It is VERY hard to see in there. Use the screwdriver to wedge from top to bottom. the flap will open downwards and then sit flat, parralell to the bottom of the vent. message me if you need any more details. hope this helps you all!
