SOURCE: SMELL IN SIDE THE CAR FROM AC

There's no cabin air filter on your vehicle. What happens is dust, lint or so-on gets trapped in the evaporator core for the a/c and starts to stink over time. Ask your local parts store for a de-oderizor spray for your a/c.

SOURCE: 07 Honda Civic air conditioner has a musty smell.

You need to make sure that the evaporator housing drain is clear. There will be a small tube or opening that usually drains out under the engine compartment near the passenger side. Run the A/C with the car raised safely, and look underneath, you should see it dripping, if not, you'll have to find where it is supposed to be dripping and clean it out with something like a pipe cleaner. Even if you see it dripping, clean it out. Then you have to buy a can of aerosol A/C disinfectant, this should be available at any good auto parts store. Turn the A/C on high and spray the disinfectant into the intake vent of the system. The location of the intake may depend how you have the A/C set. "Fresh" pulls from the outside, usually the valence right in front of the window, "recirculation" pulls from inside the car under the center of the dash. I would do both.

My car gets super humid inside and water drips over the dashboard. why is that?


Check your carpets, I bet you have a leak. If the passenger floor is wet and smells like antifreeze you probably have a leak in your heater core. If it is wet other places and just smells like musty water I would look for a leak in that vicinity (windshield, back window, door seal)

Why do I have radiator steam come thru my heating vents in my car?


Be careful with that Barsleak. Don't be surprised if you see seals and or your radiator blown out. Not only will it plug the leak but it can also plug things that you do not want plugged, such as hoses and seals

Have a vibe and am the only car in the parking lot where I will either have fogged windows or frost on the inside first thing in the morning the vibe is an 09.


Sounds like either your heater core has a small leak (usually you will smell coolant when you first turn the heat on and will be slowly loosing engine coolant) or, if the condensation is on the inside of all the windows, check the rugs for signs of dampness If you have a body leak the additional humidity inside the car from the damp rugs will cause that. If you find neither, just leave the side windows open about 1/8" and the temp should balance inside and outside and you wont see any condensation.

The windows seem steamed up defrost does not help could this be the heater core if so where is it located


first. do you smell a sweet smell in the car? (coolent or antifreeze smell?)

If you have that smell, you have a leak.

If not.... you need to make sure the A/C is wirking. I know that sounds weird, but the A/C helps the defroster work by taking the moisture out.

Heater immediately fogs all windows and there is a sweet odor in the cab of 2003 Buick Rendezvous, defroster works fine, but will not clear the windows after heat is put on


Sounds like a possible heater core failure(hole in it) the smell indicates to me the coolant(anti-freeze) is leaking into the passenger compartment.
Check the carpet in front of the front passenger seat for moisture, this would confirm heater core leak.
Good luck !

Back to problems with my 2000 Buick La Sabre. I noticed this last year and now it's happening again. Sometimes when the heat is on there is an odor that smells like melted candle wax, the smell can be so...


I don't really know what could be causing a wax smell specifically, but if crayons made their way into the duct-work then that could be your problem. Other wise you may want to inspect the heater-core, could be clogged (for debris or mold) and cabin air-filter (IF APPLICABLE).
