Autoparts places have a spray now for that, to apparently remove mold & mildew build up in the system. It has instructions on the can I'm told. Personally, I use Lysol spray, or fabreeze & aim it in on passenger side of cowl where air is drawn into the system, (listen with heater on full, standing on passenger side, down near wiper arm pivot) with heater on medium or high, I spray it in there, and then change to vent, then defrost, then floor, to make sure I get all the duct work inside. I leave windows open so smell isn't too strong. Worst I have to do is clean inside of windshield if it leaves a film. May not be for everyone, but works for me.

Car smells musty needto know where drain plug is located


the drain plugs are located under the floor mats in the floor pan . If you look from underneath you will see the round plugs .If the carpets have been wet that bad then you will never get rid of the musty ( fungus) smell . consider new floor mats

Musty smell from A/C in 2001 Pontiac Grand Prix GT SE


Most common cause is water sitting in the bottom of the a/c heater box. Make sure the outside drain is open. There are spray products for using on the vents.

Musty Smell when A/C is turned on in Pontiac Grand Prix


If your vehicle is equipped with a cabin air filter replace it. And to prevent the smell from coming back shut the ac off but leave the blower motor on to dry up the evaporator. Not allowing to dry will result in mold growth

Nasty molding musty smell...started iout of the blue. It is now early spring have not used A/C yet. It is making me sick


Musty smell comes from three possible situations.
First is simply a spilled liquid on the carpet. A thorough carpet cleaning will get this.
Second, water entering the body of the car. (IE: leaking door seals , window seals, or the hardest to find... coming in under the carpet from the floor pan) Barring leaks from the seals and spills, The floor pan has drain holes and rubber plugs that may dry out and allow water from below the car to enter.
Third, Your A/C unit is developing this condensation in the Air flow Box (complicated air flow box under dash holding your heater core and A/C core) This is a common problem, but requires a de-mold solution best applied by a Pro. You can buy over the counter solutions (sprays) and then make sure you run the heater after each A/C run. That works for many as it dries out the condensation the A/C produces.

Hope this helps.

The heater has a musty smell,I suspect i need to


It sounds to me if you are having a "musty smell" then you might have a problem with your condensation drain line for you a/c system or a small leak on your heater core. If it is plugged then water will collect in the vent system causing a musty smell from the water not draining and if there is a small leak on the heater core then coolant can collect in the vent system. I would run the a/c on a warm day and look for water draining from the vehicle around where the dash is located to check the drain line. As far as your air cabin filter most are located behind the glove box. You usually need to remove the glove box to get to the filter.

Wet floor


If this has happened since you started using the A/C it is probably the drain tube for the A/C. They get plugged and usually someone has to go under the car with a coathanger and open the tube up.

Air condition


You may have a low charge of freon, most likely about 10 ounces, as far as the musty smell that is mold from the inside of the AC air box, they make various chemical tratments to cure this issue, but once the smell is there it can be diofficult to kill the mold that causes it.

Sounds like you have a freon leak..Take it somewhere to check and while they have it let them check to make sure the air box drain is not clogged..The auto parts stores sell a spray for the air box..
