This is a common problem for all air conditioners (in a car or not), and is caused by mildew growth. In cars it often happens when people run their A/C on the recirculation all of the time, or the drain gets clogged. The system doesn't dry out completely and mildew starts to grow. You should be concerned about your health, especially if you have allergies. ...

My first concern is that you have an exhaust leak. The exhaust is designed to exit at the rear and or side of the car, far away from your fresh air intake of the ventilation system in the cowl area. I would check for an exhaust leak starting at the front as you stated that it's coming in from through the ventilation system. This can be dangerous and should ...

It is actually really difficult to top this up yourself - the easiest route is in through the transmission dipstick, so you'll need a long funnel. First, find the dipstick - it will be inwards and down below the fuel filter (your manual should show you where) - it will have a yellow circle at the end, for your finger to pull it out. Then see how full the ...

I successfully used some Griot's "Odor Exterminator" to remove a smell from my new-to-me car just this weekend. It was some sort of sweet-ish chemical smell, either from something the previous owners spilled or from something the dealer used to clean it.

I have observed this - kind of like an acrid or "vinegar" smell. You can help prevent this by turning OFF the air conditioner a couple/few minutes prior to turning off the auto. As others said, it is caused by growth of biological bacteria/fungal and turning off early helps dry the system and assists in prevention as it reduces the moisture retained in the ...

There are quite a few different rubber hoses in the average engine bay - have you check to make sure none are in contact with anything hot? Especially any that run near to the exhaust manifold. For that matter, if you can get under it, check the entire exhaust to make sure nothing is in contact with it that shouldn't be. You've mentioned the belt which ...

You may have a heater core leak. A few drops blown into the vents will be aromatic and give a sweet-is smell. Telltale signs is moisture or staining on the passenger carpet, although a slight leak may not be visible. Sometimes a very difficult repair and other times not. Depends on the car. Google will know.

If you can figure out how to check your transmission fluid level and top it off if it needs it, do so. It may already be too late to be able to drive it to a mechanic, that's a risk you'll need to assess.

What you have is the very same issue many Ford Escape owner's have: A leaking timing chain cover. My 2003 V6 is in the same boat. This is a small and somewhat annoying leak due to the fact it drips onto the exhaust and causes that oil burning smell and sometimes visible smoke coming from the right front side of the car. What I hate the most is shutting of ...

Update: The problem was indeed a leaky exhaust system! Alarmingly, the service shop I had tasked with the repair did not find this leak, but another authorized dealer found and fixed it. I'm horrified that a repair shop can manage to not find a fault like this, but glad to note that I'm not stupid: there really was a problem. Since then, I've sold the car ...

A Diesel Engine will not emit carbon monoxide no matter what. The Diesel engine, even at idle, has a ratio of fuel / air much-much lower than a typical gasoline engine. Therefore there's more than enough Os for the Cs (oxygen for the carbon) so no monoxide will ever be produced. There could be other harmful gases in the exhaust or at least it's annoying to ...

If it's a sweet smell it might be antifreeze, although you'd usually get white smoke as well.

a mixture of isopropyl alcohol and water (1 to 5 ratio/mixture) means 1 measure of alcohol to 5 of water. You wouldn't want to go the other way, in my opinion as you'll end up with a lot of alcohol, which will not only be a fire risk, but also could do bad things to duct work etc.


2

In my humble opinion, the mold could have gotten into the ducts, and you have 2 options: New Car New Ducts They can clean the evaporator and other parts, but if its in the ducts it might keep coming back if they don't get rid of it all.

Sounds like a failing A/C compressor. Assuming the car has A/C... A/C compressor is used with the defroster to dry the air.


2

Somewhere there will be a Ford spec for how much oil the engine is allowed to consume between oil changes. I wouldn't be surprised if it's shockingly high. Check your owner's manual for starters. If the oil level as measured by the dipstick never gets lower than the low end of the 'acceptable' range between oil changes, it's probably OK to leave it alone. ...

In addition to what Nick said, burnt oil also creates the burnt rubber smell. Check if there's an oil leak that could be hitting hot exhaust parts.


2

It sounds as if you have driven over a plastic bag and it got stuck to your vehicles hot exhaust. And now its slowly melting it away. You could visually inspect the exhaust to confirm. It should look like a black blob or the ruminants of a plastic bag. Make sure you don't touch it after the vehicle has been driven. The exhaust is know to get rather hot ...

Yes, driving with the handbrake on will cause brake overheating and a burning smell. If done for a long enough period of time it can cause damage to the seals in the caliper, which may require a caliper overhaul or replacement. In most cases though, simply letting it cool off will restore it to normal operation. You'll want to check it for over heating on ...

Engine oil leaks (or any other oil for that matter) can cause a smell if drips onto the exhaust. It wouldn't have to be a large oil leak to cause a noticeable smell, just even the occasional drip. I have also seen an engine that would have a small leak overnight and would smell first thing in the morning when it was started until the oil burnt off. ...

Found a bird once stuck on a radiator and also a rodent of some sort stuck around the heater core. Both owners complained of a burning smell that went away after removal of burnt corpses.

I suspect your air vents are full of mildew that moistens and thus reactivates when it rains. The other possibility would be a leak where rain is getting into the cabin, but you would probably notice that. If it is the air vents, I don't know a good way to fix it. When I had this problem, I sprayed Lysol into the vents from both inside and outside, but that ...

I have been really sucessful with Auto Shocker (It used to be called Auto Vaccine). It's a odor eliminator and it really penetrates the upholstry to get rid of odors. I used it all the time, between dogs and athletic children my car stink a lot. You should give it a try, it's my favorite. You can find it at http://www.biocidesystems.com/auto3hslanding.html

Some tips: Probably obvious, but a thorough cleaning of the car is always in order! Wipe down all surfaces and vacuum the carpets. Be comprehensive, and check for any sources of odor while doing so (spills, stains, etc). If the odor is coming from the carpets or upholstery, an even more thorough steam cleaning of the interior surfaces might be in order. ...

Since your car has a burnt electrical smell and acts like losing its power, you can check its wiring system and the fuse for possible short circuits. It will be much better if a professional mechanic assists you in repairing your car. After all, the wiring systems of cars can be very intricate, and a single mistake can cause a myriad of problems right away.

i ended up using, after extensive testing, a 50-50 mixture. Turn fan on full-blast, and use spray-bottle to spray mist into the intake. Odor eliminated; i was surprised it worked.


1

That sounds like the bearings in the fan have failed, or something is caught in the fan, stopping it from turning. I've got no idea where the heater fan would be on a Sedona, but chances are it'll be behind the dash somewhere - If you're lucky it might be on the engine bay side of the bulkhead, but if it is inside it'll be a pain to get to, and will ...

Try changing cabin Filter and see if that makes difference if you have not changed lately. Generally Cabin Filter is under Gloves Compartment on Passenger Side

You might want to consider the following answers. They might be relevant to your situation: toyota corolla 2001 air duct smell Heater smells like sulfur Why does my A/C blow foul smelling air when it first turns on? Here's a subset of what I suggested for the "heater" question: Leaking gear lubrication (which can smell like sulfur) combined with a ...

Most of the perfumes I know have a lot of carbon content (Alcohol based). So if I am to take a quick guess, this might be unburnt fuel being pumped out in gaseous form, a precursor to blackening of your tail pipes. Or your vehicle might just be wooing the beetle behind - who knows? :)
