    smorris517,

    Refer to msg#27&122 for LCD replacement procedure. You can get the rebuilt part directly from the rebuilder at a lower price than the dealer(Read older messages on this thread). The rebuilder is located in S. SanFrancisco.
  • Regarding #40 I had the same problem with my 92 LS 400. In the wiring harness mounted in the deck lid, one of the wires that goes along the hinge on the left side is too short and has broken. The result intermittent opens and the first time you hit the brakes, the system moves to the high voltage mode due to the display.
    I found this out by turning on the lights in my car and raising and lowering the trunk. Wiggle the wires in the harness withing the hinge and you will find the culprit. Simply cut and resplice to correct the problem.

    I am currently looking at buying a 1990 Lexus LS400. The car appears to be in great shape, however it has 143,000 mi. The dealer will give a 1 mo warranty but that's it.

    What am I looking at as far as annual maint/repairs go if the car was previously well-maintained?
  • I've been reading this message board over the last couple of days and I found it to be extremely useful and comforting...had I known sooner!
    As a 93 LS400 owner with 111k miles, I found it comforting to know that I wasn't the only one to with the leaky PS pump that ultimately killed the alternator...I should've heeded the dealer's warning! Well, like they say, when it rains, it pours! Now that I've got a new PS pump and alternator, my mechanic found out that the thermostat and the thermostat housing are bad too, thus causing the car to overheat. So hopefully replacing the thermostat and housing will take care of the problem. Anything else I should be looking at?How often should the radiator be replaced?
    Also, message #58 (from Sandyfordiii) was never answered. ["I've noticed my outer half of the speedometer needle in my 91 LS 400 flickered for awhile and is now just dead. Might anyone know of a fix short of a new factory part, or of a source for rebuilt speedometers / needles?"] The dealer told me that the whole display assembly needs to be replaced ($500+ total), but is this true of is he just trying to rip off another customer?
    If anyone has any answers or recommendations, please respond. Talk to you all soon!
  • Anyone watch this on Dateline yesterday?

    This is what I paid the nexus Dealer's service department for some routine maintenance services:
    timing belt - $600
    front and rear brakes - $500
    60,000 mile service - $800
    75,000 mile service - $200
    90,000 mile service - $600
  • My mechanic just replaced the thermostat and its housing and it seems like this has fixed the coolant leaking/overheating problem. But now when he test drives my 93 LS400, he notices that the temperature reading goes to the maximum hot after 10-15 minutes on the road! But when he stops and checks the engine, there are no signs of overheating. Anyone have similar experiences or comments? Is the problem with the temperature sensor? I have noticed too that when I turn on heater (doesn't matter what temperature is set), only cool/outside air comes gets ventilated. But when I turn OFF all ventilation, heat starts to come in! Please advise. Thanks!
  • My wife's 1998 LS400 has a strange and scary problem. While the car is in gear, at any moment (fast slow, stright, or turning) the drive train loses all power - like it has shifted to nutreul. The Check VSC message appears, engine light comes on, VSC Off light comes on, engine is still running, no power to wheels.

    Imagine you are turning in front of an oncoming semi when this happens - not good.

    It started one or twice a week, now several times a day. Took it to the dealer twice, he replaced the TPS sensor, then adjusted the TPS sensor. He swore it was fixed (I insisted on talking to the mechanic.) That was yesterday. Today it happened twice, once while I was at the wheel. The only fix is to stop the engine and restart the car.

    Shifting gears makes no diference - to neutral or park, the drive - but reverse gear still works.

    VSC switch makes no difference.

    Turn off the engine, start it again, everything works fine by the warning ligths and message are still there - after a while they go away.

    I'm afraid to let her drive the car.

    ps about 30,000 miles on this car

    this could kill somebody.
  • The "pulling out of the vents" refers to the A/C vents atop the automatic climate control unit. When you face the vent direction downwards this allows the tips of your fingers to grab the housing surronding the vents. if you pull outward and downward firmly the whole face with vents pops out exposing 2 screws holding auto climate with LCD in its place.

    For question about wether to purchase a early 1990 LS 400 here is my opinion. Be preapred to spend a lot of money for parts and maintenance. The car is reliable and perfoms suberp, however it is expensive to own. The V-8 only uses premium fuel, and averages 15 MPG city. The trade off is you will own and drive a very prestigious, luxury car for a lot less than what a 2000 year model costs to purchase or lease. I think, if you can afford 2K a year for up keep than treat yourself to one. I would not pay 50 grand to purchase or 10 grand a year to lease a new one so I purchased a used one for a lot less. I think it will still have a resale value when 12 to 15 years old with 125 k plus miles, there will always be a buyer for such a car. I am a car dealer and I have a 2001 Nissan sentra that I bought outright, this is my daily driver which makes 25 miles to a gallon and takes less than 3 quarts oil when changing. I have been using my Lexus on weekends so I am not running up the miles and tearing up the car. I realize this is not feasible for all people, however it is a good way to own such a car to keep costs down and its value up. I have entered my 92 LS-400 in a E-bay auction, you can check it out a white 92 LS 400, flroida car.

    The LCD unit can be purchased from Mikado Technologies 1-(650) 615-9966. I changed mine and I am very happy I did, I no longer squirm or get upset when I glance at the A/C/ unit.

    Best regards to Y'all

  • Dear Paul:
    To earn a living I am a consultant for import export companies. This occupies about 7 to 10 days a month. For the remaining time I buy and sell cars. I only purchase and sell cars I enjoy driving and repairing. This is my second Lexus
    LS 400 and I am learning a lot about them particulalrly through this message board. I do a lot of the work myself to keep busy and I really enjoy it. At auctions I select only the best car I can find and search for the service records and/or hints of one ownership. I purchased this car and invested 1000 dollars into reconditioning. I have the time and the knowledge to change the LCD for example when the average person would not have the time or know how so I do it for them. I would only sell the car in the type of condition I would like it to be if I were the customer/buyer. If I get the price I want it will be sold, if not I will keep it. I do use it and enjoy it. I have another car, a 1985 cadillac Eldorado with 55 thousand orginal miles in very good condition as well. That car is at fedcar.com it is white exterior wit red interior. It is also a toy for me to play with but, Lexus is my favorite.
    Best regards

    I just got off the phone from Mikado about the LCD unit.

    It costs $295 for an individual ordering the unit.....If you can get a shop to order it for you the cost is wholesale at $195.

    They require you to send in the unit or it costs you an extra $100.

    The invoice states that a "reman" (remanufactured) transmission was installed. Torq C is the torque converter. The $1,450 is the core charge for the original transmission, refunded IF the original is still in rebuildable condition when returned to the remanufacturing facility. You got somebody else's transmission after it had failed, been replaced, then remanufactured. Standard trade procedure.
  • Hi--I own a 94 Lexus LS400--saw your post re the power steering pump. I replaced mine at around 96,000 miles and replaced water pump and timing belt at same time. I had a serious fluid leak with p/s pump but didn't experience any other mechanical problems. Water pump and timing chain were dealer-recommended maintenance.
    I love my car and have expenienced no serious problems with it. It has 116,000 miles and I guess I will drive it until it won't go any more!
  • Was wondering if you recommend maintenance by any other dealers such as Toyota? I feel like we really take it up the tailpipe when these Lexus dealers are the only game in town. I have received solicitations in the past from Toyota for service but have been reluctant to try it.
    I recently had my "94 LS in for service and attempted to have them order me a new ignition key with remote. They wanted $350 for ONE key so I told them to keep it. My remote button broke off when I dropped the keys but it isn't worth that much for a new one
  • I would not have a problem allowing a toyota dealer service a Lexus. I might ask for some references, perhaps other customers who are satisfied. Dealers, new car dealers that is, tend be reliable but expensive. Lexus cars have numerous shared parts with toyota autos. you can also try a smaller reapir first ad see how it goes?
    Best of luck

  • I own a 91 LS 400. It is in immaculate condition. Currently, I have 121,000 miles on. This a great car except for one big annoying problem. She has terrible brake squeal at very low speeds, such as 5 miles per hour. The Lexus dealership tells me this is a common problem and is due to the mettallic brake pad. My pads were changed at 90,000 miles and I have 70% left on them. But this noise is embarrassing. Can anyone help??
  • I have a 94 LS400 with 116,000 miles on it and the brakes have been screaming since the first month that I had it--same problem that you describe at very low braking speed and especially when you are creeping along. I complained loudly the first year but got the same answers you did. I guess I have just learned to live with it! You would think as much as these cars cost, they could find a way to eliminate the noise as it is
    rather embarrasing.
