Forgive me if this is the wrong area to post in, it's a question about ventilation.
I have a 2002 E270 CDI which in the lightest of rainfall steams up inside. Obviously I can switch on the AC and clear within a couple of mins, but I don't like to just run AC all the time for reasons of economy and also the dryness which gives me sore throats etc.
There are no water leaks into the interior(doesn't steam up when left parked) and in dry weather the steaming up just doesn't happen. But drizzle for a few minutes and hey presto it looks like something illicit is going on in my car - for which I am too old before anyone asks .
Is there a drain or similar in the air intake which could be harbouring water?
