Water in Passenger Footwell of 01 S280

[s280man]

The passenger footwell and even rear passenger footwell have become very wet.

A few sites have suggested that the reed valve that drains water from the fresh air intake can get clogged and could lead to water in the passenger compartment. The water seems to be coming from above the passenger footwell directly behind the glove compartment. Where exactly is this reed valve and how does one get at it?

The air conditioning also stopped working recently, probably due to overuse trying to clear a constantly fogged up windscreen due to the dampness in the passenger footwell. I read something about a blower motor fuse holder that there was a recall on and i took out this fuse and put it back in and it solved the air con problem but the ECN button on the air con unit remains on and will not turn off even if it's pressed.

Has anyone else experienced this type of problem or would there be other causes of this dampness and ECN light always on?

Hi & Welcome,

Quite common unfortunately, it will be the drains at the bottom of the windscreen which will have blocked. Water then gets through the heater into the footwell. If you open the bonnet into the service position you can then get a better view. Clear out all the leaves and crud you can see in the first instance. You may also have to remove the plastic covers to get it all cleaned out.
It has been covered previously on the forum so pls have a search around.

When my dash was replaced under recall couple of months back MB also fixed the water problem. Check with your local dealer.
