Also available is an A/C sanatizing spray available at most auto parts stores - like this http://gngsales.com.au/products/deta...rosol-auracsa/

I used a similar product in my Dodge - and it worked great.

Like sleeper, I try and remember to turn off the a/c a mile or two before I will be turning off the car.

Ok this makes no sense the smell has gone away completely. I did not do anything. The only thing that has changed is the weather it has gone from dry and cold to wet and some what cold. I have run the defrost, no defrost just straight vent air. Any ideas or just enjoy the sweat smell

Mine will get a "musty" swell on those warm, damp days. Usually at start up and goes away after 3-4 minutes. No smell on the colder and/or dry days.

I found out what was stinking up my ventilation system or I should say my boss figured it out for me. The windshield washer fluid bottle was contaminated and smelled like puke so every time i sprayed it on the windshield it would run down in to the intake and the ventilation system would start to stink.

Mystery sovled.

Well that's one I wouldn't have thought of.

Go to your local auto parts store. There are several aerosol products made to spray into the vents to clean out the nasties. The problem arises from a clogged drain vent; that small hose sticking out of the firewall passenger side.

Dumb question- Do you remove the cabin air filter before using the spray?

Read the directions on the product. I would think you would so you can access the pan from the cowl.
