Musty/Mildew smelling interior?

[MGM1979]

In the SC2 - it's MOSTLY obvious when the air is on, so I tried changing the air filter (is there no cabin air filter?)...didn't help. Nothing, that I can reach, seems/feels even a little moist inside the car. Put your nose in front of the air vent, and there's NO doubt about it - SOMETHING is stinking up the car, just can't nail it down.

The car sat for a while, I guess, before I bought it...I've had an "ant" issue (crawling around on top/inside), but I haven't ruled out the source being the tree in the front yard yet (g-f parks under it for shade) - could have something to do with the smell???

Any ideas of what to do, where to look...ANYTHING???

a/c drain line clear?

a/c drain line clear?

bingo.

If the line is clear and dripping do this.

turn the blower fan on (NO A/C) and let it run like that for a good while, you may have some shit inside the case and that should dry it out and should help quite a bit.

right there with you. hehehe

if it still smells like mildew... build up in the ac vents... a little bleech pored down the air in side and left to evaporate will kill the mold that causes the stink... its at your own risk but i've done it with a few of the vehicles i purchased in the past and its done the trick
