ECON stinks to high heaven. I used two cans of air con fresh made by carplan... and it got rid of the smell for about a month.. AIRCON mode is fine though.. Changed the cabin filter and it was full of all sorts of crud... the smell is still there... so I am guessing that there is mildew in the duct work... Q. Is there a cabin air intake on the underside of the windscreen or something? may be on the bulk head? im planning on spraying fabreze or something into it with the ECON on max. mode. Thanks.
