air conditioning stinks

[power4l]

Over the last week, when i first start my truck it blows out nasty mildew smelling air for the first 30 or so seconds. Had the truck since last fall and it never smelt like that till recently when i've really started using the ac. Any ideas?

I have no idea what is causing this either, however my wife's 2008 VW Jetta started doing it this summer bad enough we have to crank down the windows until the smell passes. My 2008 PSD just started this year as well, is there any maintenance we should be doing on these AC systems (filters?).

Check your Cabin filter.

Where is it? the ford dealer told me these trucks didn't have one. He said only the new f150 has them.

turn your AC off and run just the vents for a couple of minutes, with the fan on high, before you turn of your truck/car. it gives the system time to dry out. that should solve your problem.

Good lord I hope there is a filter or your just sucking in what ever is in the air outside into the cab. Can anyone else confirm or deny a filter in our trucks?

i got a spray can of "clean air" brand duct treatment from autogeek.net and sprayed it in the outside air intake(which is at the base of the windshield under the plastic cover there on the passengers side) with the ac and fan cranked and it took the stench away for a several days, but now its back. I know i got plenty of the stuff in the system so i guess it was just a waste of money. I tried an odor bomb too. Turned the ac on recirc. and locked the trigger on the can and left it, truck running and the ac on for about 25 min. Still only lasted a couple days.

I live in a small town so letting it run for a few without the ac on-before i shut the truck off-isn't really an option.

The place i park my truck overnight is a little higher on the pass. side. Could that cause it not to drain right?

Its from condensation building up in the vents on warm days after the A/C is turned off, and then mildewing.. I had a tech at the dealership say to use a can of Lysol and spray it into the fresh air intake area described previously. That is supposed to kill the mildew and the stinky smell. I haven't tried it, so if anyone does, let me know how it works out.
