I mean it realy stinks. 2004 Explorer, start up vehicle A/C starts up and it has a mildew smell for a few minutes. It is either a mildew or musty smell, but it goes away. But stop in the store for a few minutes, start it back up, and there it is again. Any ideas? Thanks

all i can suggest is make sure you drain for your A/C is free of debris, then ask around at some auto parts stores for products that are used to eliminate A/C odours. Ford has a special chemical used in a spray bottle in which you need to remove part of the plenum to spray this chemical on the evaporator. Some other products ive used is an aresol can you set in the vehicle and open the can setting your A/C on max and letting it circulate for 15 minutes with all windows shut and all that it seemed to do the trick

I've heard of that problem but I think it only happens in high humidity places.

One of the mech at ford garage told me that the hose connection for the drain is to small, and at a incorrect angle to drain competely . mildew and dirt can clog the drain.I just poor a little bleach and water to keep it clean .

My 98 did that, and my 01 does that. What I try to do is run the vent (no AC) for a few minutes prior to shutting the truck off. That way it gets rid of some of that moisture.

Well I called the dealership to set it up for a appt. He told me on the phone, before I brought it in to try a few things first. First turn the heat on and let it run, then let the air run. He told me not to always leave it on MAX a/c, and make sure when you shut the vehicle off, to turn the knob from MAx a/c cause that shuts all the vents off, and it gets no fresh air. I tried it and it worked, no smell no what so ever. So it came out good in the end. Thanks for the help.
