strangest thing happened recently. monday morning I get into car and go to school with fan on. (no a/c) it smells normal. nothing new here.

then after school, I get in my car and turn the fan on. i began to smell this horrid stench. it smells like something got wet and sat there forever.and when i turned the A/C on to cold, it smells normal. only when i have the fan on it smells. and only when the car is in motion it smells. when i just get in my car it smells like my air freshener(squash!) but when i start driving, it smells like crap.

help?

 

That stinky sock smell? Yeah. Leaves and debris (sometimes small animals even) get into the vents below your windshield and work their way into your heater box behind your glovebox. It's a real pain to get out. In fact, if you have AC you can't really remove the box w/out disconnecting the AC lines. But what I did was open it up as much as I could and used the sharp vacuum extension to clean it out. Major pain in the ***.

 

yikes. do you have any other suggestion on how to get rid of the smell? will using those "smell-be-gone" sprays from auto stores work?
