A/C smells bad
I've searched for posts about this issue, and haven't found anything, so if someone already answered it, please forgive my lack of search skill.
It's been warm enough in the Houston area to need the air conditioning for the last couple days (until this morning thankfully... got us a good norther through...brr). Anyway, the smell emanating from my vents can best be compared to the smell of cheap tennis shoes which have gotten wet and then put up in a closet or other poorly ventilated area. It STINKS!!!
Since use of the A/C is intermittent during the winter, I realize that there is an area in the ductwork that can sit blocked off for a while when we're on full heat (and not defrosting). What is odd is the smell - this makes me think the drain for condensation from the evaporator coil is plugged.... anyone on here ever experience that? I haven't had a chance to crawl under the truck and look for it, but looking under the hood didn't make it obvious where that drain is. Once the blower has run for a while, it clears up.
Thanks in advance for any help.

Its the start of mildew from condensation....make sure your ac compressor is on when the heat is, that will dry the air, meanwhile,
try running the heater on high to completely dry out the duct system, then let it cool slowly...with the system off, spray a little lysol air freshoner down the vents.
