Mold and mildew builds up in the system from moisture in the air, dealers have chemicals they spray inside the ducting to kill these molds and mildews, the service runs about $100, there is no permanent fix, this will need to be done from time to time as req'ed, a short term fix is to spray Lysol into the heating/AC air inlet at the base of the windshield, run the blower on high and set to outside air, spray in about 1/2 can and then turn of the system and let it set.

2008 impala, terrible nauseating odor from heater


sounds like a mouse nest in hvac system, no smell because when using ac it doesn't use outside air, probably a nest on the screen at the hvac air intake or if you have a a cabin air filter check in there. many times rodents make nests have babies and then the car moves and they cannot feed the babies and so they die and rot smell comes into car. usually it is not hard to access because there should be a screen between the outside and inside under the cowl cover, if no screen and the little buggers vot into your hvac duct system this could be a much bigger problem entailing removal of dash completely. most likely this isn't the case, good luck

Bad smell from heating system


I would guess so because there should not be an odor coming from your vents and if it is worse when the heat is on there's a chance something literally crawled up there and died! I always wanted to say that not referring to peoples butts. lol But all kidding aside. You would be surprised at the little critters that can find there way into your venting system. Or just organic material that has gotten in there somehow and decayed. Best of luck tracking down those oderiferous emanations.

Ac not workng


The musty odor is moisture in the HVAC box. Someone needs to check and see if the system is full of freon, then check the circuit going to the ac clutch for power.

Hi,

Its your thermostat control which keeps switching between hot and cold.

It maybe the climate control unit.

Check these and get them tested.

Hope this helps

Musty odor coming from AC vents the last 2 days. Is there a filter some where that needs to be changed?


there may be a cabine filter. but if you leave the a/c in max when you leave it overnight, condensation builds and mold can form in the vents. try leave the control in a/c normal or vent. this opens the outside air door and allows fresh air to enter and dry condensation

There is a musty odor when I turn on the A/C on my 2008 Toyota Highlander. How do I eliminate it?


Best would be to clean the evaporator housing, it could dusty thus the water from condesation doesn't all pour out of it some remain and never dries up thus the odor.
Hope this helps!

Gas odor coming through the vent when heat is on


Did you check for any gas leaks ? Check for gas leaks all over the engine. This is not supposed to happen. There is no way that the gas could get into the cooling system. The odor has to be coming from a leak or maybe the carburator (if equipped) flooded. If the odor goes away. , it may have just been too much gas to the fuel system.

Dirt blowing out vents and has a bad (musty) odor


If you live in a dusty area it is a good idea to use the recirc button on your a/c control head. This will keep the dust to a minimum.
To get rid of the smell you can take a bottle of air freshener and spray it in the heater box air intake that is located just below the windshield on the right hand side of the van. Do this with the a/c on and blowers on high.
If you use recirc as much as possible the dust should slowly work it way out of the system.
If these fixes don't help the dash will have to be removed and a/c evaporator will have to be cleaned or replaced.
