I get a really bad odor when I turn on the A/C or the Heat. Do anyone know what is the cause of this and how to repair. Thanks.
It's the filter. Sometimes they get a type of mold that smells bad. I'd say change it as fast as possible, otherwise you can even get health problems
Good-O...!!What year Lexus and model do u have? Certain toyotas and lexus models had that same issues in the 90's and on forward in the 2000's. I've seen this issue numerous times and the cause of this is the a/c expansion valve going bad causing bad odors in the car. Have your lexus dealer look it up instead of doing cover ups, thats sum shady sh** they doing. As a Toyota tech, that would be the smelly moldy issue that u are complaining about.
The most recent case in my dealership was a 93 MR2 turbo. The expansion valve was covered in icky greenish mold and smelled so nasty. The master tech replaced the expansion valve, along with new o rings for the lines, recharged and retrofitted to r134a instead of the old r-12, flushed and cleaned the system and used a good deodorizer through the a/c vents. Worked great after that.
Lexus has been VERY well aware of the mould and mildew odor problem, and the possible harmful effects of that along with the use of the anti-microbial chemicals and sprays used to combat the problem since at least mid-1991 according to the documents we obtained in the process of the lawsuit I filed (and lost) at the time.Thank you for the info WWEST.
My car was a 2004 SC430. I was literally forced (by my Doctor) to get rid of the car, after the HVAC system was finally replaced, and Lexus USA told me they would take full responsibility if anyone else got sick.
Unfortunately, the story didn't end there. In addition to the mold exposure from the car, I also had "long-term" anti-freeze exposure. In spite of complaints to the local dealer about the terrible odor from the A/C and also anti-freeze odor (for over a year), the problems were not properly addressed into the damage had already been done to my health. I am now forced to take medication (three different ones) twice a day FOR THE REST OF MY LIFE. If I fail to take the medication, I will get sick with edema within about 12 hrs. Not a very good way to go through life.
The Doctors will not talk about how much time I have left, because the anti-freeze literally goes through your entire system, damaging kidneys, joints, etc.
The sad part is that ALL OF THIS COULD HAVE BEEN AVOIDED, if I had a competent tech working on my car that did more than just spray conditioner into my ductwork. Lexus USA also could have taken me out of this death trap much earlier, but they chose to keep me in the car for another six months, even after they were notified that the car was making me sick.
I think this is the worse car company on the planet, I believe they have know about the problems with their HVAC systems for years, and continue to hide the truth from the public.
I, and moreso my attorney, were basically il-prepared to "combat" the Lexus legal team and their ability to get the dealer employees to lie and mislead the court. But my lawsuit had to do with the horrible propensity of the LS400's HVAC system to cause sudden unexpected fogging of the interior surface of the windshield.Thank you for your response. The anti-freeze exposure and mold exposure were two separate problems that caused seriously bad results. The mold problem, which I believe developed from an engineering flaw in the design of the evaporator fins caused me many health problems. The anti-freeze exposure was a result from a defect that the local dealer failed to address, even after adding over two inches of anti-freeze to the reservoir in a "closed" system. Obviously, either of these problems is very serious.
The attitude from Lexus was always one of denial, and delay. In fact, they have actually destroyed evidence and material that may have been extremely beneficial to any possible treatment from the mold exposure.
All in all, it is my firm belief that Lexus has known about the flaws in there design, and has covered-up this problem for years. They represent EVERYTHING that one can imagine that is bad about any corporation in my opinion.
Why did you not win your case? Did they destroy evidence in your case too?
ALL air conditioners will have some propensity to develop that dirty gym socks odor. An A/C will condense moisture from the atmosphere and it is that moisture that the microbes breed and thrive in. Beginning in the late eighties there was an industry wide drive on to improve automotive A/C efficiency and it appears to me that NipponDenso of Japan was the "ring" leader in that effort.Well, I have to disagree with you about your acceptance of the A/C odor. I have worked with cars for 30 years, and have driven 100's, if not thousands of cars & trucks. I once purchased 170+ cars in 72 Hours as a Buyer in the auto business, and ran the A/C in EVERY CAR, and NOT ONE had a bad odor.
The Lexus problem, while not limited to Lexus, is a design flaw, and it is not just a nussance, but a DANGEROUS HEALTH THREAT. Anyone that with knowledge about this will tell you the same. The confined area of an automobile cockpit makes this exposure that much more concentrated. If you have the slightest concern about mold in your home, times that by 1000 when considering the exposure you would get in your car.
In regards to the anti-freeze; my Doctors estimate I was exposed to over 40x the safe limit, over an extended period of time. My symptoms are "classic" examples for both exposures.
Nothing would make me happier than putting the executives from Lexus USA in jail, for refusing to get me out of that car, when they knew that it was harming my health. You will be hearing about this case on the National news broadcasts, as we ramp-up the information in the public sector in the next 10 months.
