Every time the weather changes from cold to warm or back
again, we usually wake up some dust that has settled in the heating or cooling
systems, and that's why you get that temporary aroma when the heat or the air
conditioning has been turned on for the first time each season. No big deal, and it usually works its way out
after the A/C has been on for a couple minutes.
But, if your air conditioning has a foul odor coming from
the vents that just won't give up, you might want to investigate further.

| AHHH, what is that smell? |
Your ventilation system brings in air from the outside, then
cools it or heats it. You've got some
filters in there that try to make sure it's just air going through, but it's
not perfect. If you get a smell that
seems to be more like gentle aroma of the space between the toes of a marathon
runner, you've probably got some bacteria in your system. Yuck.
Spraying some disinfectant in the evaporator will usually do
the trick. That is, if you can get to
the evaporator. It's usually right
behind your glove compartment, so you may need to take some stuff apart. If you don't feel like doing that (and who
could blame you), you can first try to blast the disinfectant right into the
vents, then blast the air conditioning for 10 or 15 minutes. Many times that can solve the problem.
If you are smelling oil or gas when you turn on your a/c,
you've got some bigger issues and it might be time to bring it to us here at US Automotive.
Enjoy the fresh air when you can...! But, if it's not so fresh in your car, we
hope we were able to help!
