Default Air Conditioner Smell

I - 2002RS - get this awful smell (mouldy/musty), for the first minute or so, when the air conditioner is turned on. Does this mean that there is a leak somewhere. I think I saw a thread on this, but can't find it.

Thanks

it's mold. clean out your in-cabin air filters that filter the incoming
air into the cabin area of the car.

I believe the filters are right below the grill next to the firewall,
but I can't be sure.

I've recently had the same happen to me. I read
a tip to leave the fan on for a couple of minutes
to help evaporate the moisture.

Another thing to do is to pop the hood and spray a little Lysol while running the fan.

It is mold for sure. There are products that you can spray onto the evaporator that will kill the mold. Lysol will work for a short time, but you will need the proper industrial stuff to really kill it. Frigi-fresh is one product that works like a champ. Leaving the fan on for a little while will also help, but it needs to run until the evaporator dries which can be up to ten minutes.

The opening in the evaporator case for the fan resistor block can be used to spray the core directly and also to clean the core and the case.

Where do you spray Lysol? Do you spray it onto the pollen filter behind the glovebox? Or the other filter Scuzzy mentioned? And where exactly is that filter?

PS: Hey Rich, thanks for the springs install again.

Spend a few dollars and get the industrial strength stuff. Most local auto parts stores should have it as well as the dealer. It must be sprayed onto the evaporator core itself or darn close to it.

Thanks guys. Solved the problem by running the A/C on "Fresh" - apparently running the A/C on "Recirc" for extended periods was the root of the smell.

I guess, if repositioning the "Recirc" to "Fresh" doesn't work for others, the next step would be the sprays.

I'll do springs all day long. Thanks for choosing us to do it.

The best thing to do is spray it directly on the evaporator. GM actually sells a kit for their pickups and suvs that comes with a long tube with several holes in it, and a can of aerosol containing mold killer. That is a very easy way to get the whole evaporator, but the cost is quite high for the kit. If anyone wants info on it, ill call the dealer and get you the part number.

The GM part number is 12378554 in the US, or 88901678 in Canada. Theses are from service bulletin number 00-00-89-027a. These should still be valid numbers, but if they no longer are, just ask your counter guy for the odor eliminator kit for a 2000 s-10.

I thought I read a while back that you could also stop the smell by simply turning the heat all the way up, fan full blast and ac on.

Never tried it so I don't know if this would work or not. Just something I read.

The GM spray is also sold outside the dealers under AC Delco name, but still costs about $50.

Pardon the newbi-ish question, but where exactly is the evaporator on the WRX? I would like to know exactly where I can spray this Frigi-fresh stuff. So I can get the Frigi-fresh at an automotive store or should I go to a Lowe's/Home Depot? Thanks!!!
