    it actually wasn't for the heater core, the hvac housing was holding water from the evaporator drain tube being shoved up during assembly, but it would be the same for a heater core replacement.

    According to flycaster there is a newer solution where they go in through the bottom of the car and do not have to touch the interior.

    There is a third solution, which I use. A few minutes before my destination, I turn off the AC compressor, but leave the fans blowing. This does a good job blowing out out hoses and vents. Then there is no condensate to cause a stink the next time you start.

    Check around this site. There are already several threads on this topic.

    I always just leave my A/C in Auto and have never smelled anything on startup. I have in previous cars done what JavaGirl suggests and turn off A/C compressor a few blocks before I get home, but I don't on my ATS. I have noticed that majority of complaints with A/C mold smell live in the South where the humidity is higher.

    Experienced mild smell on startup in summer here in Southern Ontario, but haven't noticed it since it got cold.

    ----------

    Dealer did an HVAC update last time I was in for service. I wasn't clear what it was for. Was it to address this issue?

    I live in Hawaii and I have the same issue. I have been using the technique that Javagirl mentioned and it works. I will keep doing this until a standard, safe, procedure comes out to fix the problem without tearing up the entire dash!

    I told my SA to let me know when they are proficient at performing this mod. I figure I'll get it looked at next summer. Never had the musty smell too bad just a little on start up in the summer. My driveway is on an incline and the pan really drains heavy when I pull in the driveway but not when I park on flat surface.
