Lexus GX 2004-09 :: 2008 AC Vents Spitting Out Charcoal Like Flakes / White Dust And Fibers
Jul 17, 2013
My AC vents have charcoal like flakes (disintegrate if you rub your fingers together) in addition to white powdery dust and fibers coming out of them. I have had the car to the dealership 3 times. The first time they replaced the drivers side left vent (claimed deterioration of the vent) - the second time they sent it back with nothing and the third time they replaced the evaporator coil. I'm still having issues with this material coming out - I've had the car for about a year and half and really don't want to get rid of it!

So my AC has been making a smell that smells like dust. I searched the forum and found threads about mold, but this isn't a mold smell (or at least what I think mold smells like). I thought it was because I was using charcoal cabin filters but I just bought a new plain filter and I get the same smell. The smell usually happens when I first turn on the car and then goes away after 10 minutes or so and the smell almost always happens when I go through the carwash.

I just picked up a 05' F450 Super-Duty it had the rear seat removed and the rear wall, under the window is bare metal. I have all kinds of road noise and dust coming in through the two vents on the back wall. How to fix this?

I have a 2004 Camry that has had ongoing issues with the Charcoal Canister over the past 3 years. The first time we came across this issue the car threw codes that indicated the Charcoal Canister had to be replaced. Our mechanic said it had to be done and there were no after market parts for this canister. We paid the $800 for parts and labour and had it replaced. Then 13 months later the car began throwing codes again. I had the car looked at again I was told the Canister would need to be replaced... They felt it was likely caused from the intake filter housing cracking. Each time our car does this the codes can be cleared for a bit but the car takes forever to fill and slowly over time you can no longer fill the car as there is so much pressure. This time I bought a used part and replaced the canister. This has happened again..
So we have now replaced this filter 3 times in three years. Can I ask how this canister continues to get gummed up? We live on dusty roads in the country but none of my other Toyota's have had any issues with this. How these canisters are getting gummed up? Is there any way for me to change this Canister myself if I buy them used? I saw in a video on this forum where the user shows putting the car up on a hoist and lowering the exhaust to get to the canister. Do you have to have a hoist? I am wondering if I can achieve this with the car on a blocks? My original mechanic said the rear suspension needs to be taken apart to access the canister? Can I ask where the dust is being drawn from to clock this filter to begin with? I have also been told you can try blowing out the lines? How to attempt this?

I was filling up at Costco and for some reason it was taking forever for the pump to stop. There was an attendant right next to me so I asked her if the pump has auto stop and she said yeah of course. I began telling her that it usually doesn't take this long to fill up and the next thing I know the pump started spitting out gas. So after I put the nozzle back on the pump I took out my camera and recorded the spill... after about 20 seconds I'm just holding the camera so it is pointed towards the ground, but you can hear a conversation I had with the attendant.
I know what you are not supposed to top off the car so to me the spill is much worse than topping off with the prius's bladder system. I was afraid to turn on my car and afraid of any damage that may happen.

I just took the car to the dealer, for a recurring Check Engine light, and after changing the gas cover 2 months ago, now they tell me that it needs to replace the Charcoal Canister pump . I have a 2008 Prius, bought used 18 months ago, with approx. 70k miles

About 3 months ago I noticed at times my Heat would blow out cool air. This would happen mostly when I was sitting idle or in traffic in a "stop n go" situation. I did some research and found out that my Coolant was on the low end. I bought the Pink Coolant from the Lexus dealer and filled up.
I checked the levels again a few days later and it was low again. So I topped off again and looked for any puddles underneath the car when sitting, I paid attention to any smells, and looked to see if I was blowing white smoke out of my exhaust. NOTHING! My indicator stays on the middle range and never runs cold or hot.
I topped off after seeing that it was low again and didn't have to put as much in there, but it definitely was low again. It's now been about 2 weeks and it's still at the same spot (near the low indicator) but it doesn't seem like it's getting any lower. I have done more research and I cannot find any issues with the 2008 LS460's having issues with head gaskets or coolant issues.
I recently had my bumper replaced at the Lexus dealer Auto Shop because of a pothole I ran over that dinged it (also bent my rim)....I know this might not have anything to do with it but I thought I would add this tid bit since I didn't notice the issue until I got it back from them! I'm just really at a loss

I was driving into work this morning. I initially had my windows down, vent on, blower on 1, fresh air. It started getting warm as I sat in traffic, so I hit the A/C button, then hit the recycled air button. White fog started coming out of the vents for about a minute. After that, it went away. I didn't smell any freon, but it's got me concerned. Do you think there could be an A/C issue? I just got the car last Saturday?

I have a 2004 f150 with 2 of the 4 A/C vents are broken, I just want to replace them. I figured the dealership would be a rip off and I didnt see any on ebay. And how to take them out?

I recently went on a road trip and at one point white steam started coming out of my AC vents. i pulled over on the side of the road to take a look under the hood and everything was fine. no burnt smell or anything. i was driving through some high temps (around 100) and it was a bit humid. i figured it might have been because of humidity, but I've never seen that before. now a few days later I'm back in arizona and this morning i saw the steam coming out again, but very faintly. Its also very humid right now. The AC works fine, blows cold air like it should.

I have a f150 2007 with a 4.2 in it. The CEL comes on and when this happens the air comes out the a/c vents and no where else. We have cleared the code out but it comes back on when we do clear it out the air blows out where the dial is set. I think there is a vac leak somewhere....

I have a 2005 F150 4X4, has 43,000 easy miles on it. When I started the truck I notices white smoke come fron the exhaust. It was a cool morning and the truck was sat for 24 hours, I have read some post about how that could be the reason. I was also told that adding a quart of lucas in place of one of the (motorcraft synthetic) quarts.

I'm having intermittent problems with the air conditioner on my 2004 Hyundai Santa Fe. If it matters, it's a 2wd, 3.5 liter model with about 66,000 miles. Below I will post a description of what's happening, as well as some other things that I've noticed and things that I've tried (these may or may not be relevant to the problem though). OK, here's what's happening:
I first noticed the problem back in late July and since then it has been happening more frequently. So far the problem only occurs after I've been driving on the interstate, although I'm not sure if it's a matter of my speed, or just a matter of how long the a/c has been running. Typically I only drive 15 minutes at a time unless I'm on the interstate where I would typically drive for a few hours or so. What's happening is that after a while (the time varies from 20 minutes to an hour or so) the flow of the air conditioning coming through the vents slows down to just a trickle. The a/c is still really cold, but it just barely comes out of the vents, no matter what speed I set it on. Here are some things that I've noticed (and a few things that I've done to try to repair it):
1.) I read that it might be the cabin air filter, even though normally Santa Fe's aren't equipped with them. I took the glove box out, and found the spot where the air filter normally goes and there was one installed (we bought the car used). I took it out and it was disgustingly dirty - a bunch of dirt, some leaves, sticks, etc... I just took out the filter completely and didn't replace it.
2.) While I was looking at that air filter, I also noticed that the box right to the left of that filter was wet with condensation. This was right after a two hour drive with the A/C on maximum cold all the way home though, so I don't know if that is normal or not. It wasn't dripping on the floor, but there was noticeable condensation on that box (I don't know what that "box" is).
3.) The problem will sometimes go away if I turn the air conditioning completely off for about 5-10 minutes. It seems that the longer I leave the a/c off the better chance I have of it working when I turn it back on.
4.) When I change the fan speed on the air conditioning I can hear the blower motor running at different levels. It almost sounds as if there's something in the dash that is clogging up the pipes. I can hear a whistling sound when the blower is on the lowest speed - when it's up any higher than that I can't hear it, but that's probably just because of the noise coming from the blower itself.
5.) I had the problem today, and I stopped at a gas station to get a drink. When I got back into the car I heard the sound of water trickling from underneath the glove box. It was very quiet, but it was there.
6.) When we have this problem, it happens on all of the vents. It doesn't matter what vent you choose for the air to come out of - the flow is just a trickle.
7.) It doesn't matter if it is heat or cold - the flow is very slow on both of these.
8.) The a/c is still ice cold during all of this. It blows colder than any other a/c that I've ever had.
9.) I noticed that sometimes while driving, a white mist will come out of the vents. Sometimes we have the problem above after we see the mist - sometimes it still works fine though, but I did think it was odd that the "mist" was coming out. I'm not sure if it's water vapor or what, but it does go away if you turn the temperature control a little to the warm side (even just a notch or two away from max cold).
Originally, I had thought that it was the blower motor and I was just going to replace it, but then I started thinking about it and don't think that it is the blower motor because it seems to be working well most of the time, and even when I have the problem I can hear it running - again it sounds like something is clogging up the a/c system somewhere between the blower and the vents. I also read some things about the blend doors, but I'm not sure if that's it or not.

I've noticed a strange problem that makes it next to impossible for me to use his truck unless the vents are off or I have both windows all the way down with it on. It smells like it has a fuel leak of some sort and in the cab of the truck it smells bad while driving and gets worse when sitting still, to me it smells like gas and when I open the hood on his truck after idling about 5 minutes or so I can smell it in there so i know its somewhere under the hood but for the life of me I can't see anywhere where its leaking or anything like that but I can smell it all darn day. His truck is an 05 F-150 with a 5.4 and I'd like to figure this out before it becomes a real big problem. I've worked with fuel injected cars and trucks before but I have little knowledge of the mod engines at all. And he is still driving it like that and I just wanna make sure it either is not gas or is just something simple I'm overlooking.

2008 honda accord coupe ex-l
So, I assisted my sister in finding my nephew a used car and everything looked great on the surface as well as mechanical. We get the car home and the SRS light comes on.. I started digging into why and find there is dirt dust all behind the dash and side panels around airbags in back and pretty much everywhere below the surface.
Digging into the service records I see they did have to replace a fender liner which might have been a port of entry for all the dirt and dust. Apparently the young driver was putting in mileage on dry dirt roads without a fender liner.
I did caution against buying this car previously, even before looking at it, because it was a teenage driver, there was a minor wreck into driver's door and repairs had to be made for him running up on a curb as well. But in their desperation for a car.. they asked me to check out the mechanics of it.. i did.. they looked good.. but I missed all this dirt dust and now i feel bad.
Anyways, how to go about cleaning out all this dirt dust behind the dash, and panels of the car? I worried if I leave it there, he will experience additional expensive electronic issues.
Was thinking of taking off some side panels and dash off, and using a vacuum with a brush head to try and get it.. I could use compressed air.. but perhaps that may be potentially harmful to other electronics and connections?
As for the SRS light, i was able to count the light flashes in dash to get code 8-3 off of the flashing SRS light and a 7-1 off the ABS light. Referencing those: "Internal Failure of SRS unit".

I had my 2006 GX 470 in for 30k service last month. Cabin Filter was replaced.
Now with the temp set to 68 degrees, outside air on, the vent(AC off) blows hot air, usually when using the car first time in the day. Sometimes, after a while, cool air starts blowing in. I feel something changed after the service. If I set the temp to MAX Cold it blows cool air. I have had this car since 2006 and not seen this behavior.
Currently its cold in California so outside air should not be hot at all. I also experienced this when it was snowing outside, during our Reno trip.

I have a 1996 Suzuki Swift. My defroster stopped working several weeks ago.
If I have the defroster and heater on at the same time, white vapor smoke comes from my vents. My heater works fine when I choose the vent option for it to blow directly on me but I can see and smell light blue smoke if I change the vent option to blow on my feet.
In addition a thin white film covers my windows while I'm driving whether I have the heater on or not (and there's a slight oil smell in the car if the heater is on - I do have an oil leak). The thin white film can be wiped from the windows easily at first but becomes more difficult to wipe after 30 minutes or so of driving. Once I turn the car off, the film disappears within 6-8 hours.

My ex-wife has a 2008 Prius. When trying to get heat, either using Auto A/C or manual, the display panel shows that only the floor vents are open. However, forced air is flowing from the upper vents on the dash. The air from these vents is not warmed. It seems to be unheated outside air. It's unclear whether this is a new problem, since the owner doesn't know if this behavior has been there since she bought the car. She does report that the car has always taken a long time to get comfortable in winter.

I found a loose blue/white ground wire in my engine compartment. Where this exactly needs to be ground ed to? Been having dash cluster light issues also.

Why these air vents will not lock down. No matter how hard I push down, they will not lock. Check out the pictures, if this doesn't make sense. Notice the driver-side vent is perfect.
Stays elevated and won't click down.
Taking the air vent piece off.
Same thing with the windshield defroster.
Lifting up the defroster.
The driver-side.
