Whenever i leave my car parked with all the windows up, cold or warm the car always seems to become very stuffy and humid. I am not sure if it is becasue of my A/C or something else, or if its just me, because the other cars dont feel this way and the rest of the world doesnt feel that way so can anybody give me some input ?

 

stop farting......but on a serious note that is strange. you live in AZ so humidity should not be an issue as far as i know

 

Do you leave the AC controls on recirculating air mode all the time? Use the fresh (outside) air option whenever possible. Also, make sure your AC evaporator drain hose is not plugged. It drains the moisture from the cabin to outside, under the car. If you see a puddle of water under the car when you park, it's working properly.

 

I shut my a/c off about a mile before I get to where im going and let the fan blow the system out. If you dont blow your vents out sometimes moisture will collect in the ducts and smell musty.

 

did you have a bottle of water open inside the car? otherwise it's normal

Same. Still haven't identified the source.

 

I had same issue with another car. I found water in passenger floor. mine was due to heater core leaking which is not your issue but I would feel around make sure carpet isn't wet some where.
No mousture in cabin = I have no idea.

 

Throw this dehumidfier in the back seat...

 

get some window visor and crack the window open a little

 

I replyed but it never got though, no my AC controls arents on recirculate and where would the AC evaporator hose be exactly?

 

Changed the cabin filter lately?

 

I had a service a little while ago on the checklist it says fine, but where would this cabin filter be located?

 

check 3G garage for DIY cabin filter change.

 

Living in FL, we deal with a lot of humidity issues, and even though it doesn't seem like I have excessive humidity, I keep a hanging "Damp Rid" thingy in my car to avoid any strange smells from starting. It's meant to be used in your closet to reduce humidity, but obviously works in the car too. It has these crystals in a plastic pouch that dissolve and any excess water is "caught" in the lower part of the pouch. When there are no more crystals, you change it. You should be able to get them at your local supermarket and they are less than $10 for a pack of 3. I saw them at Costco a few days ago. http://www.bedbathandbeyond.com/prod...p?SKU=12105975
