    After checking several sources, I have concluded that the AC filters in the RX300 and the Toyota Highlander are in fact the same. My Lexus dealer wanted $61 for the filter, so I purchased the filter at the local Toyota dealer for half the cost.

    reliable sources on the Internet...but are you sure that 2x4 pine boards won't work just as well?
    Think I'll do some experimentin' this weekend.

    Also, are you aware that covering the OAT sensor with double-sided tape causes less windshield fogging? Has to do with the negative ions from the tape inhibiting about 50% of the neutron catalyst activity.

    Can someone email/explain how I do make the edges of a 3M furnace filtrete to fit the RX300 filter?

    I made a cabin air filter for my Quest out of filter material (wasn't 3M) I got at Home Depot. I cut it to fit and stuck it in the housing that the OEM filter was in.

    btw, I can't tell that it's especially effective, but neither could I tell that the OEM one did a whole lot.

    I have found that Purolator will introduce a Lexus RX300 PremiumPLUS® cabin air filter, P/N C38222. Their application guide says "Not Available - Availability To be Announced":

    Filter Application Guide

    I have contacted the manufacturer to see when these will be on the market and will post the result here when I receive it.

    Send Purolator this link.

    (Hint - Purolator's home office is in Henderson, NC)

    I am looking for a new RX300. There are no more in Hawaii. Anyone else recently purchase one or see some on some dealer's lots? I would prefer the Western states since shipping will be too high from the Central or Eastern states.

    Thanks!

    Another question: Anyone have the light green RX? I've never seen one, just the paint chip at the dealership. Is it light on top and darker on the bottom? Got any pictures?

    I love my Nav even with all its flaws. But it chooses the strangest routes sometimes. Rather than going straight to a destination which would be the shortest route, it many times takes me to another street. I realize the other street has a higher speed limit, but it is not the shortest route. Does anyone have any clue as to the logic that the nav uses? Does anyone have access to Denso engineers? What algorithoms does they use? Maybe Willard knows.
  • gteach26gteach26 Member Posts: 576
    have always done the same thing to me too. They'll get me where I'm going but not always using the most direct route. I think picking the "shortest time" route will get you on expressways 90% of the time even though there may be a quicker way through regular streets. What I love about these systems is that no matter how many goofy turns I make my little sexy computer voice gets me where I need to go (as long as I've input the address correctly).
  • wwestwwest Member Posts: 10,706
    All I can tell you is just be patient and wait for Denso to discover/realize for themselves the Nav flaws. In the meantime buy the aftermarket non-captive nav.

    In the meantime just carry a paper map along and cross check the Lexus nav rather than have it lead you astray.
  • wwestwwest Member Posts: 10,706
    It's been eleven years since I made it very plain that the denso climate control design was seriously flawed, both with regard to defogging the windshield and keeping it defogged, and the issue of human body comfort and radiant heating/cooling and I have yet to see them take any corrective action whatsoever.

    Other than, that is, committing fraud on the court by secretly modifying the firmware in my 92 LS climate control system.
  • wwestwwest Member Posts: 10,706
    If you think it might help I believe I can give you the name of the Denso engineer who Lexus brought to the US in 92-3 to reprogram my climate control. The court transcript is around here somewhere...
  • pschiffepschiffe Member Posts: 373
    They replied promptly but were non-committal, here it is verbatim:

    I am sorry, but Purolator product management has not published a projected
    date of availability at this time.

    Apparently those Denso engineers don't know when to quit. My NAV suddenly (and without warning) fogged up! When I opend the hood I discovered a Denso Engineer secretly hiding inside my firewall with a cup of dry ice and a battery-operated fan.

    Talk about fraud...He said he worked for Delco!
  • wwestwwest Member Posts: 10,706
    is history, it's Delphi now. And if you care to look about you will discover that Delphi is addressing the issue of windshield fogging at this very moment, very successfully, it appears.
  • squacksquack Member Posts: 27
    Hey, the engineer said Delco. I guess he lied about that, too

    So, is Delco addressing windshield fogging by suing Lexus? Maybe we all can help...

    All those who've sued Lexus, and won, raise your hand!
  • plumbstarplumbstar Member Posts: 12
    Are there a set of actual rules that the Nav uses to plot a course? Does anyone have acess to Delco/Denso/Delphi?
  • wwestwwest Member Posts: 10,706
    Delco engineers with their hand raised, what could it mean?
  • jeffmust2jeffmust2 Member Posts: 811
    ...to slap you?
  • squacksquack Member Posts: 27
    I guess that's the total of people here who've sued Lexus, and won.

    Hmmm...No help there. Darn! I guess we'll have to go at it another way. At least we might prevent getting slammed too bad by not involving anyone that might hurt our chances of success in correcting the fogging issue.

    Okay, all those who've sued Lexus, and lost, raise your hand.
  • wwestwwest Member Posts: 10,706
    Final evidence not in....
  • jeffmust2jeffmust2 Member Posts: 811
    ...to gather all that evidence.
  • wwestwwest Member Posts: 10,706
    Let's see one of you try and prove Lexus reprogrammed (or not) my 92 climate control rather than admit a flaw.

    I'm fully and completely open to suggestions of ways to check the original 92 "firmware" against the "firmware" of the 92 I just bought.

    One of my complaints back then was that on a cold morning the windshield would begin to fog up when the system blower activated, a few miles down the road, as the engine water jacket reached 130F.

    Until I bought the other one recently I hadn't noticed that the original 92 blower now comes on with the ignition. The "new" one still has a delay until 130F. I can't be sure until I check that the 130F sensor hasn't failed "on" in the original one.

    Planning to do a complete test series with the original 92 and then install the climate control module from the 92 I just bought and repeat the test to see what's different.

    Can't seem to find the documentation for a "core dump" of the microprocessor/microcontroller memory.
  • wwestwwest Member Posts: 10,706
    I only knew that A/C was used to cool the passenger cabin, it's been a very long learning process. Now I know what an EPR is, but I still can't figure out why Lexus used one in the 92.

    Do any of you own a bike rack that have an rx 300?If you do what kind do you have top of car or back and what brand, Lexus or other and how do you like it? Thanks
  • squacksquack Member Posts: 27
    The Judge ruled on all the evidence presented over a decade ago. The public record shows that, or has Lexus reprogrammed it (or not).

    I'm guessing (See hoping) the right of appeal has expired.

    Revisionist history is boring and completely unflattering.

    I have a hitch bike rack for two bikes. Slide it in the hitch and remove it in 60 seconds. I bought it at Wal-mart on the close-out shelf for $29. I forget the brand, but it was heavy duty, so I tried it. Noproblems at all. Love it!

    About 100 years ago today (now that really is OLD!) many very well educated folks were saying heavier than air flight was NOT possible.

    Aren't we all really thankful today that the Wright brothers were high school dropouts???
  • squacksquack Member Posts: 27
    ...are even more boring than revisionist history. There's no honor in quitting school, nor any reason to glorify it.

    Well educated Flat Earthers & Geocentrists once held sway. They were wrong, as well. Whoopideedoo!

    Fraud on the court? Unless it was an attorney, or the Judge (Some officer of the court) it's not "fraud on the court"...Sorry.

    Maybe there was a shot at perjury, or perhaps aggravated perjury or falsifying evidence, but the statute of limitations passed long ago.

    Bailiff, next case!
  • wwestwwest Member Posts: 10,706
    assuming that the Lexus attorneys weren't knowledgeable of what was done.

    On reviewing the transcript it becomes quite obvious that the attorneys knew what was up. Way too many questions for me as a witness about "it hasn't happened again, has it", and questions of that ilk.

    My answer each and every time was "hey, it's summertime (while thinking "you idiot"), no it hasn't happened again, the climate isn't right."

    I must assume that had I ever answered in the affirmative the attorney would have immediately sprung his "trap" and accused me of perjury since their "cure" made it unlikely it would happen again.

    high school dropouts, but on entering the 10th grade I was taking my needed four courses/credit (all A's) first thing in the morning, cashiering in the lunchroom in return for lunch for myself and my two younger sisters, then getting on a bus for downtown where I worked as a shipping clerk until 6PM except on Thursday, I worked until 10PM and Saturdays from 10 to 10. Up at 4AM to "throw" two paper routes.

    During the same period I often filled in for a friend working as a licensed fizzician (soda jerk) when he decided he wanted to "play".

    The principal noted that I was missing most home room periods (didn't see the sense), and introduced me to the local USAF recruiter.

    But the bottom line is that you are perfectly correct, there is no glory in dropping out of school.

    But occasionally there is something called necessity of circumstance.

    You keep badgering me about my seemingly frivolous pursuits but I must tell you that my insatiable curiosity regarding digging into and finding out how things work, or not, has served me really well in this lifetime.
  • squacksquack Member Posts: 27
    Actually, ridiculing would be a more accurate characterization. I
    learned this subtle difference as a high school senior...Whoopsie!

    Sure would like to find an ECU piggyback or JetChip style upgrade
    for 20-30 additional HP and corresponding torque.

    Anyone seen a device of this ilk?

    Aren't we all really thankful today that the Wright brothers were high school dropouts???

    Just to be clear about it - Wilbur was a very serious student and fully intended to become a teacher. His family's move from Indiana back to Dayton in the very same month he was to have graduated from high school prevented him from actually graduating.

    He did, in fact, return to high school the following year to complete the program but suffered a severe accident about halfway through which prevented him from finishing his high school education. Moreover, it prevented him from his plans to attend Yale.

    That's not exactly your typical "high school dropout" by any stretch.

    We now return to our regularly scheduled program ....

    Yes. The typical one does not go out and invent manned flight! :-)

    Curtiss was a graduate of Boston College, and he let his work speak for itself, and didn't spend his waking hours in patent litigation (except in defending against the Wrights' suits).

    Here's another blurb about the hybrid RX 330 (aka RX 400H):

    Much of the Wright's design and success was derived from his research (Over 2000 flights). Had he not died, he might have been first.
  • jeffmust2jeffmust2 Member Posts: 811
    ...any chance he was entering Nav info before his death?
  • bobfloydbobfloyd Member Posts: 32
    High school dropouts, lawsuits, flight, flat earth surely do positively contribute to the RX 300/330 discussion. Even the hosts participate in such mundane banter. Can we return to the subject soon?
  • steverstever Guest Posts: 52,454
    But most of the interest in the RX seems to have shifted to the Lexus RX 330 discussion. Or the Owner's Club, linked at the top. Check those out too.

    1) High school dropouts - the chief RX designer in the mid 1990s was Hiro Suzuki - who was, as you guessed, a high school dropout in 1960s Tokyo before Toyota hired him as a mailroom clerk.

    2) Lawsuits - hey, blame Willard; he's still fighting his LS/Denso HVAC courtroom battle from ten years ago

    3) Flight - apparently, Denso supplies the same exact HVAC and Nav system to Boeing and Airbus as they do to Toyota & Lexus...strange - but true!

    4) Flat earth - I believe this relates to the RX's poor off-road capabilities.

    So, none of these topics are off the point and we should continue to discuss them over and over.

    Sorry.
  • wwestwwest Member Posts: 10,706
    leave the LS climate control issue/discussion over on the LS thread. Okay by me.
