Title GLOVE BOX DOOR CHECK-ARM RATTLE

CONDITION:

A rattle or squeak noise from the glove box door area may be apparent when the glove box door is closed and/or the vehicle is driven over rough roads. This condition may be caused by the movement of the glove box door check-arm against the glove box door and/or the checkarm through hole in the dash

REPAIR (INSTALLATION) PROCEDURE:

To reduce the possibility of the check-arms rattling or squeaking, (1) Glue a small piece of felt to each edge of the through holes and (2) Place a felt washer on the check-arm pivots at the side of the glove box door--(See illustrations below for more details).

PRODUCTION EFFECTIVE:

From the end of October, 1989

From approximate VIN # JT8UF11E-L0010276

yes on ls400, and many rear wheel drive cars, behind rear seats is the tank

on front wheel drives, fuel tank is normally under the rear seat giving more space for the trunk

1990 ls400, when i run on uneven road at > 50 mph, i feel the car is bouncy (or floating) more than enough. I often hear the sound when tires touch the inner wheel arc. both front and rear wheels.

what should I replace? the shock absorber (damper) or the springs?

in places: combination meter, inside fuel door, Lexus put some words: "Premium unleaded fuel only". i am wondering what kind of premium is that. i am now using A95 gas, the most premium (if most expensive means that) available in my country

should I try the alternative A92 which is less pricy? what octan you guys are using?

have tried A92 one time, i felt a short lag in hard accelerations. is A92 the cause?

on 90-94 LS400, simply remove the EFI fuse located in the fuse/ relay plastic box sitting next to the Battery for a few minutes

my 1990 ls400 got same symptom, 2 electronic fans in front of rad always run when i turn ignition on regardless of engine temp or air con on or off

in lexus service manual, there is a check procedure for control of these fans, but too busy now for that

driving a nissan bluebird for many years, i never planned to buy a lexus until the day a friend of mine, who buys and sells old cars, introduced the 1990 LS400 to me, i had a week test drive and decided to buy it.

Why?

1- Affordable: bought it for US$ 18k

2- buy one get all: the car has almost all things i ever expect for a car: stylish appearance, quietest car, great stereos, tilt/ telescopic steering, leather seats... and many many more that others are only dreaming of

3- durability: first test dride was surprising for a 15 year old car. still as smooth as new, and there is still no signal of getting old

in my opinion, Lexus for suitable for people who drive and enjoy the car by themselves (dont have a driver)

i like the rims. seem like yours has a headlight washer, is it OEM or aftermarket? my 1990 doesnt have it

this link wont really address what you want but it is the way to get access to the back of your stereo system where the back lighting is

Hello all,

the ex-owner of my 1990 LS400 has changed its original rims from 15"to 16" everthing seems okay except that the speedo meter indicates wrong speed. GPS shows my car running at 100km/h but the speedo meter tells only 80km/h

i guess this is because the rims have been changed to a bigger one with bigger dia. which cause wrong speed calculation

my question is: can i replace the current speed sensor with the one for LS400 93-94 models which use 16" rims?

i dont want to go back to 15" rims that means i need to pay for 4 new rims and tires. also, the new rims make the car look nice actually

thanks

Hi Steve2006,

i got it, the button accepts one more down press, window goes down automatically :-) but it does not auto going up (maybe for safety reason)

thanks all for your help

Hi ontheroad1, could you please send it to me as well. i got the same issue.

qha_vn@yahoo.com

thanks a lot

Hi ontheroad1,

do you remember exactly what was displayed on the radio LCD when turning on the key? is that "SEC"? just to make sure :-)

thanks

i will try again the way Steve2006 advise (i used to do it on my previous nissan bluebird)

if it wont work, then yes, replacement of the main switch is needed. but am wondering if there is a way to test and make sure that the auto functionality completely fails

yes i did

Hi all,

my 1990 LS400 has auto-window on the driver side but i cant use it. dont really know how to activate auto mode. every time passing toll, i need to keep my finger there until the window is all the way up and down

any help?

Thanks

Hi eXOBeX,

when i turn on the key, radio display doesnot say some thing like SEC. so the security code is probably inactive

thanks

Hi ontheroad1,

seems that we dont have a way to post pix or upload file

could you please send your setting instructions to my mailbox qha_vn@yahoo.com

but for me, posting it here will help other people to get benefit

thanks a lot Royt

the pauses make a difference as it is definitely not easy for people to count the number of flashes up to 22 times :-)

thanks eXOBeX,

yes, it is the stock radio theft deterrent system

i will have a look at radio display while turning on the key few minutes from now (going home)

i am just afraid that if the ex-owner has activated this system (and probably with new code) then i am in trouble

Hi Royt,

i have some questions from your instructions above:

1- so Tranny must be in N (neutral) and not P (park)?

2- the number of check engine light flash on and off will determine the erro code? say if the light flashes 17 times meaning error code 17?

thanks

i have just purchsed a 1990 LS400, i read somewhere that if the security code has been set for the car, when i disconnect and reconnect the Battery (for any electric fix) the car will require security code

unfortunately i cant contact the ex-owner now, anybody can help?

thanks in advance

am a new member and a brand newbie to lexi

i got the same seat memory issue with my 1990 LS400

can anybody advise Ontheroad1 how to post pix or attach files?
