After I shut off the air conditioner when the fan runs, I get bad smell?

Question

After I run AC for some time, when I shut off, I get bad smell from fan. I get this even after I change the air filter. This is not a old car and I have only 25,000 miles on it. How do I circulate the new air inside the car? Any suggesstions?

Answer 1

The above response was close.
There is a product on the market developed just for this. You can buy it at nearly all auto parts houses, and the instructions are on the side of the can. It comes with a little jet tube to direct the spray, and it really works.
The problem with the A/C is that the moisture in the air condenses on the A/C evaporator just like a cold glass sweats in the room. In the A/C system, the moisture collects, and this along with some biologicals in the air will begin to-- grow---- things....
This will begin to smell bad, and can contribute to breathing problems for some people whose breathing is already compromised, or are particularly sensitive to mold and mildew.
If you cannot find the product, you can get pretty good results by spraying something like LYSOL* into the cabin intake for the A/C system.
In order to use it, it must be on MAX -A/C, with the blend door in RECIRC mode.

Good Luck

Answer 2

If you have a max a/c setting, turn it off and let outside air come in. If you have not been turning off the a/c and letting the fan run for the last few minutes on the drive before turning off the car, you have not been getting the moisture out of the system. You need to get it out every time or risk getting mold in there. You are smelling stale moisture.

Answer 3

the smell you get is the condensation that has the humidity smell (is an urine like smell) at thei point youll should try to run the ac on fresh air before you turned it off for a whie like a few block before you get home , this will increase the flow of fresh air to the condenser minimizing the amounts of humidity that accumulates , also spray some ozium to get rid of tyhe smell for now, spray it under the glove box with the ac full blast and in circulate mode.
