Funky Oder from vents
I get a funky odor from my ventilation system when switching from vent to ac and vise versa or if I start my truck with the ac on! Any thoughts on how to take care of this? With out just an air freshner which I tried already just smells funky plus the smell of the freshner!

Outside dismantling the dash and going after all the vent tubing and the evaporator core, air freshener is probably your only option.
You can tell it's getting oppressively hot out, this the second or third smelly vent thread in the last week!

at the local parts store about 2 yrs ago I bought a Deodorizing spray specifically made for A/C vents
you spray it in there and let it sit for a few minutes
then turn on the a/c and run it full blast with the windows down for 10 minutes or so...worked pretty good on my 1994 F-150 in the Seattle area

i have used a product that is a foam cleaner. there is a nozzle and tube that attaches to
your ac drip line.... push the tapered nozzle that and spray the foam for about 15-20 seconds long enough to get the foam to the evap core pull the nozzle from the drain hose
let it drip out and repeat... i usually do it three or four times. this has a anti bacterial cleaner as well a a light scent.
if anyone is interested pm me i can get them for $15.00 plus shipping.

If you use the recirc often you may start smelling a moldy ordor due to the ac system not drying out. Several products are avalible to spray into the cowl intake while ac is on, they kill the bacteria. After installing the spray in the future it is best to shut off ac before you park and run fresh air thru vents to dry out system. Infiniti's are nortious for this because they start up on recirc mode and most owners never switch to fresh air. I know I have one.

Turn off the AC & recirculate for the last couple minutes that you are in your truck. It will pull most of the moisture out of the core & ducts and drastically reduce the mildewy smell when you turn the system back on.

You can buy a huge spray can of 'OZIUM' at beauty supply stores and maybe other places. With the engine running, start the AC and turn it to MAX (recycle, recirc). Go to the passenger's side, open the door and find the fan intake grille under the dash. Spray the OZIUM directly into the fan for about 10 seconds. Turn everything off and shut up the vehicle for as long as you can. The musty odor will be gone for awhile, and if you do these other little precautions, you might get rid of it.
