Well that was a fun couple of hours
I bought the new MB part from the UK dealer and 7 cross head screws and 4 bolts later, was able to get to the old one. This was sitting horizontal rather than at the angle shown in 91lux's picture. So it was sitting on the two fresh air flaps...
While in there, I de-gunked everything, vacuumed everything and gave it a good clean. Passenger side drain was blocked, which may explain some of the water ingress on that side on wet journies. I also have a little surface rust in there as well
. A de-gunk and a quick clean (and removal of air filter...)has done wonders for the heater levers - they move a little more freely!!
It's all still in bits as my flap and rubber seal (above the filter) had both been (over)sprayed car colour and the seal in particular was the worse the wear for it. So.... new seal has been ordered...screws/bolts cleaned off etc.
While it was all in bits I also took a few minutes to clean/grease around the wiper spindles.
