AC smells from mildew
 This being my 3rd Avalon (probably my last one as well) has a terrible smell coming from the AC vents.  Dealer says this is normal, well it is not nor is it acceptable.  They recommend changing the cabin air filter.  It was changed to no avail, smell still there.  Dealer checked the drain and all appears OK.  There appears to be a design flaw in the drain for the AC evaporator for which they will do nothing.
