1999 Honda Accord Question: replace cabin air filter
Answer #1dandd December 09, 2010, 13:53Master
The cabin filter is behind the glove box and is not that difficult to replace. It is also possible that your heating system may have some mold or mildew inside. I have seen that cause very offensive odors as well. There are some sprays that will kill the mold/mildew and can be purchased at a good Auto Parts Store. I would not just spray in bleach, because that can get on to your seats and leave big white spots!
