My CPO '11 Lux has a strong odor coming from the air vents. First thought it might be some kind of air freshening canister that was injecting the fragrance, but now wondering if I have an antifreeze leak???
View 6 RepliesSo my vents stopped actuating to different positions in my 2011 6.7 F350. I read that it could be a vacuum pump or solenoid issue. In any event, I turned 4x4 on and went down the street and made a u-turn - 4x4 seems to be on as the truck wants to hop the outside wheel when turning. I want to check the vacuum pump anyway but for the life of me cannot find it anywhere. Moreover, google turns up nothing which is making me start to believe the new trucks have a completely different system.
View 9 RepliesEvery time I turn on the a/c I get a horrible smell coming through the vents like old sneakers or a gym bag that has not been cleaned out in some time. I thought it was just because I hadn't run the a/c all winter, but it has been doing it every time I turn the a/c on or off. Have any of you run into this?
View 2 RepliesMy wife was in the car today, and complained about a strange odor coming from the A/C vents. I would describe it as a slight vinegar/alcohol/sour odor. I think it is from the A/C vents.
View 40 RepliesSo I've been noticing this for a while, pretty much ever since ive had my car. I have a 2011 camry se v6 and when i go hard on the gas from a dead stop or accelerating on a on ramp on to the freeway i get this smell coming from the vents that smell like rotten eggs or something and my friend in the back said he can smell it too. This only happens when i accelerate really fast and shoot up to or over 4500-5000 rpm, why? i use cheveron 89 gas which is plus.
View 14 RepliesI have a 2011 BMW 328i and I get this sort of burnt chemical smell through the vents when the heat is on. It doesn't happen until I have been driving for 10-15 minutes. After that you get the smell on some low level all the time, but it seems to be briefly exacerbated by making a hard turn (i.e. a U-turn). You get a stronger whiff coming out of the turn and then it returns to baseline. I also smell it stronger when setting off in low gear (1st or 2nd) like from a stop sign. It happens whether the car has the air re-circulation on or not. It has been in for service twice and they can't find the problem. The car is a RWD manual transmission and only has 20k miles on it. I checked the fluid levels and as far as I can tell they don't seem low. I looked in the service history and a coolant leak was fixed at one point, near the thermostat - yet the car still exhibits the smell. In addition to the smell, it kind of irritates the back of my throat after a while.
View 12 RepliesI few weeks ago noticed musty smell out of my air vents but didn't mind it thinking it something temporary. Mind you that this only occurs when i have just the fan running without the AC or recycle feature. I opened up the filter and cleaned it out of debris. Looking at the filter it seem like it got wet because of color change that occurs on it, brownish(muddy). I bought the car pre-owned almost 10 months ago, had one service done but unfortunately Hyundai dealer scheduled the service hour before closing down and i think they didn't mind checking the filter, let alone checking tire/brake tread and no car wash.
View 9 RepliesMy fiance has a 2011 Corolla LE. A couple years ago this weird smell started coming through her AC vents. It is intermittent happening when the car is parked or in drive. Once the smell comes through the AC the only way to make it stop it to push the AC button so that normal air blows through, turn outside air on, or switch the AC air speed a couple times, or just wait a minute or two. I changed the engine and cabin filter, sprayed the vents and everything else with cleaner and check the drain tube. I don't know what else to do.
View 3 RepliesI got my first Toyota couple months ago, Camry xle i4 38k. Everything is fine except for the not-so-smooth tranny, but I get used to it. The thing annoys me is the moldy smell from the vents. I usually turn on fan (A/C off, inner circulation on), when notice the smell, I changed the cabin air filter (the old one has tons of dirt!!). the smell goes away, but whenever I put on defroster, it comes back.
View 11 RepliesI get a musty odor from my vents from time to time. It usually happens on days when it is damp out and often on startup but sometimes it happens later in the trip. Its quite strong, unpleasant, and terrible for allergies.
I read something about this a long time ago but cannot find the posts. Found a TSB summary on VW's site but Dealer pulled it and says its for Passat. Thinking its something in the A/C or ventilation system.
I have a 2000 Ford Excursion v10 that won't divert air through any vent. Blower motor works through all speeds from low to high. I hear air being pushed around but doesn't go to any specific vent (barely comes out defrost and front vents though). Temperature Blend door and actuator for door work fine. Vacuum tested and no leaks. Opened up the glove box to expose heater core, noticed the vacuum actuated rod that sits to the left of the heater core is sloppy and barely moves up and down when controls are changed. I believe there is another vacuum actuator in the dash somewhere closer to the driver's side that may pose as a fault as well.
View 6 RepliesMy 2003 Passat has a musty smell coming from the HVAC system that just won't go away. Have resealed pollen filter and had airsept treatment (this worked for a while, but now the smell is worse than ever). Two dealers have tried (and failed) to fix this. It's so bad I can't take passengers in the car.
View 5 RepliesOur 2002 Camry SE V6 incurs a burning odor through the HVAC system after braking from moderate or higher speeds (at low speeds, this does not happen). It can last for a few seconds or a few minutes and then goes away (it does not happen while in motion). I cannot smell anything outside the car.
The car was inspected & serviced two months ago with no issues found. The front valve cover was replaced about a year ago but the back valve cover was OK to leave as is.
I would want to say it is the brakes or the snow tires causing the odor but it is strange it only smells inside the car.
Two related problems:
1) Our 2008 dodge grand caravan's recycled cabin air/exterior air flipper is broken. You know, makes the clicking clunking sound until it gives up?
2) Unfortunately this has made the exhaust smell that much worse.
Usually when you drive above 35mph you don't catch engine fumes, but when its anything less you fear you're poisoning your family into early cancer. Obviously we have a leak in the HVAC system somewhere and anytime we take it somewhere for service on something else they just shrug their shoulders.
How to locate the leak so I can keep the engine compartment out of our a/c?
This noise has been posted several times recently and I have also experienced similar sounds. Whining in the drivers side dash area. Dealer states that it is fuel pump and that it is normal. Well, it has been a lot colder here in the last week and the noise has become louder, a couple of times to the point that it was hard to carry on a conversation with someone in the vehicle.
So I started investigating and found that if I turned the HVAC fan all the way OFF, which turns the system off, then the noise is gone. So my noise has to be associated with the HVAC. Complaining of this same noise coming from the drivers side dash? Also found same noise when I would use the REST.
I've got a 2004, V8 with about 65,000 miles. If its 75 or above and the ac is running the HVAC will start this whining or chirping noise. It seems fan speed related. Its coming from the passenger side, not the drivers side as some of the other posts mention with their situation.
View 1 RepliesIt seems my car likes leak gas smell, its not leaking gas but the smell is strong and comes through my vents when the air is on, and also is in the car after high speeds (like getting off highway and stop at stop sign) also will work its way into my car when not running..
I noticed when i bought the car that the previous owner had replaced things under the hood and took off ALL the covers under the hood (the plastic covers under the hood, for example the v6 30 valve piece and the one running horizontal for the air cleaner across over top the battery), so my air cleaner is exposed at the top, so could this have any effect on the smell?
I am getting a plastic or oil smell from the vents. I read about this on hear a while ago but I didnt record the problem. What that is. Oil leak from engine seal? I don't know...
View 4 RepliesI have a strange (musky) smell coming from my air vents when i turn on the air. I was told by the dealer that this could be mold growing inside the vents because I use the AC a lot. Is there any cure for this besides going to the dealer? they told me that they can partial get rid of this by spraying a chemical into the vent but they cannot guarantee that it will work.
View 19 RepliesI noticed a few months ago I wasn't getting much heat from my 99 Passat. I had the cooling system flushed and checked. Still no heat even after having all this done. Not long afterwords I started noticing that sweet smell through the vents, but couldn't find any leaks. I checked the expansion tank and it seemed to be slightly low so I added some coolant just to top it off and there it was. Steam started rolling up from the drivers side where the coolant had dripped on the exhaust and that's when I found the leak. I took the screws out that hold the tank to the bracket and discovered the leak coming from a short tube that appears to connect to nothing leaking coolant. Now here's my question, is the tank suppose to have a hole in it ? I thought it was suppose to be pressurized. What I don't figure is why didn't the shop notice it when they were refilling the system.
View 9 RepliesSo, at 14k it looks like I have that musty smell coming out of the AC vents. I've seen a TSB on here that addresses it. Hopefully my first trip to the dealership for anything other than an oil change doesn't present me with any other surprises.
