I have had my 2013 Edge in twice for this problem, and was about to do it again. My car only smells terrible when it's humid out, so in the Fall, it's hit or miss whether it's humid or sub freezing and dry. However, it blows out of the vent for the first few minutes. I have a mold allergy, so it makes me it hard to breath. The first time my car was into service, they replaced the cabin air filter. The second time, they replaced the AC condenser. Neither time did they smell it. I've asked that someone who doesn't smoke or breath in fumes from cars all day give it a try.
I'd rather clean it myself if I can, even if it has to be done often. Is there an online manual (not the standard one from Ford, it doesn't give any details) that I could get access to that would walk through how to, and where to, clean the lines?
thanks!
