#174 of 193 Re: Foul odor from interior air vents [wwest] by amauhry Jul 17, 2008 (9:37 am)
Replying to: wwest (Jul 16, 2008 4:43 pm) I live in the east, New York City to be precise. This region seldom experiences what you’ve described. Usually we get high humidity accompanied with temperature increase or vice versa. Obviously ambient condition for the eastern part of this county do not call for residential HVAC with the remix/reheat mode; so, I guess, this system is not sold or rarely sold around here. If it is, it would be redundant to have the remix/reheat function.   Based on your explanation, it makes perfect sense to have one of these for home application in your area/region. Kool!   I did not mean to offend anyone about being ignorant. And the fact is, we don’t know everything. Why do you think I joined this site in the first place? My knowledge is not absolute my friend, and the potential for learning from other people’s experiences is what makes forums like this…well...PRICELESS.   Amaury ’08 Limited

...and, of course, that makes me share my own experiences and point of views.   It is a win-win situation, and we all are the beneficiary   Amaury '08 Limited Replies to this message: wwest (Jul 17, 2008 11:35 am)

Replying to: amauhry (Jul 17, 2008 9:41 am) I would imagine that even in your area of the country there would be a fairly large number of people that would be comfortable with the elevated temperatures were the Rh not so high.   But that's where those portable dehumidifiers (COOL an then REHEAT) probably sell like hotcakes.
#177 of 193 Air Conditioner Smells by belaircarguy Jul 26, 2008 (3:06 am)
I live in an area of the country with high summer humidity. I operate the A/C in all my vehicles in the recirculation mode all the time all summer. Many newer vehicles (first one I had was a 98 Olds minivan) have an interior air cabin filter. This is generally located on the lower part of the dash on the passenger side (but check your owners manual). These filters will get dirty and musty and create that foul smell when the A/C is turned on. Never really noticed it with the heater, just the A/C. Open the small door / cover for the filter and pull the filter. Take it to Pep Boys or your favorite auto supply store and get a replacement. I change these in each vehicle once per year and no more smell. I found this by experiencing the same smelly problem until I discovered this quick and easy fix.
#178 of 193 07 Avalon Touring White Powder from AC Vents by manav82 Oct 21, 2008 (11:29 am)
I own an 07 Avalon. I used the heat for the first time this fall and have noticed white powder coming out of the vents. The rear seat and dash have a thin layer of this powder on them. I have checked the filter and it is clean. Has anyone else seen this or have any ideas? Thanks.

Replying to: manav82 (Oct 21, 2008 11:29 am) I have an 06 Limited and had this problem one year ago. They replaced the condensor and just last week, this happened again and they are replacing the condensor again. Evidently there is a service bulletin out there on this. Also, in repairing this, they have to take apart the whole dash and center counsel. Took three days to have this done both times and the first time I had to take it back about 3 times to get all the rattles fixed from them messing with the dash and such. Have not picked it up from the second repair but I am dreading the inevitable rattles. Would like to know what this particulate is made of and if there are health issues with inhaling it, I assume it can't be good, but have not found the info.

Replying to: bhawks (Oct 30, 2008 4:11 pm) Thanks for the post. Any idea what the TSB number is so I can let my dealer know. Thanks,   Manav Replies to this message: bhawks (Oct 30, 2008 7:09 pm) Mr_Shiftright (Oct 31, 2008 7:47 am)

Replying to: manav82 (Oct 30, 2008 4:19 pm) No, sorry I don't but when I pick up the car tomorrow I will see if I can get a copy. If I don't get it, just tell the dealer to call toyota as they do know about this. Good luck

#183 of 193 Re: 07 Avalon Touring White Powder from AC Vents [manav82] by wathan Jan 07, 2009 (7:25 pm)
Replying to: manav82 (Oct 21, 2008 11:29 am) I too have an 07 Avalon with the dusting problem. Mine started in Sept. 07 the day after I had service done which included changing the cabin filters (maybe a coincidence). I thought it would stop, but it kept getting worse. With the holidays and being busy I never took it back in to the dealer until Jan. 5th. They've had it 3 days and say it will be ready on the 4th day. They said that the evaporator had a "new" coating on it that caused a seal to deteriorate causing the dust. My concern is what the health hazards are for breathing this dust for the last 3 months? Anyone know how to find out? I haven't had as much as a cold for several years and now since November I've been fighting upper respiratory problems - can't help but think they're related.   Any thoughts?
