thanks for the quick reply so there might be an unexpected short in mute line? how can i test it? my car doesnt have phone option. Also my car was imported from US so there would be no difference (yes VN stands for Vietnam)

my radio suddenly went on mute mode yesterday (it worked normally just a few hours before). It does not produce any sound at all at any volume level, at any preset anf non preset radio station. the radio unit looks fine when i turn it on, all lights are lit, radio statiions display normally. the only thing is no sound at all i tried to find a "mute" button but it seems not have any. any idea? ('90 ls400 with 90k on it)

thanks, i will find somewhere and try a hard brake. by the way, do your seat belts lock on quick pull?

ls430 is addvertised as "all new design" version of ls series since 2001, it also discontinued ls400 production. i dont think the improvement is marginal. however, exterior design is not appealing to me comparing to ls400

i notice that my ls400 seat belt (all seats) do not lock when i pull it out quickly as it normally does with other cars. would this be a problem and how to check to make sure that they still work? thanks

so speed makes the difference. in city, always stop and go, highway 60km/h average :-(

try this '90 ls400 repair manual Idle_air_control_valve.pdf

dont worry about the lower panel as it is hang up by some clips. But you may need to investigate the wavy airbag panel, it might be the indication of airbag having been deployed. in other words, the car might be in a serious accident

new car models have a useful feature that automatically adjust mirrors down for driver to see the rear wheel and pavement. '90 ls400 does not have this. is there a way to mod?

great finding, could you post a pix of the hose you have replaced? that would surely help us not to replace the wrong ones

hi everyone, i dont have the owner's manual and cant download it from lexus.com as it requires registration and registration requires an address in US that match my car VIN. i am in VN would someone be kind enough to attached it here or direct me a site to download thanks

i bought FULL repair manual for LS400 1990-1994 from tradebit.com, paid by creadit card before i got the password, what i received was the INCOMLETE set of repair manuals for LS400 and a full set of SC400 manual. so you better verify with them before you pay

good to hear. 225/60 R16 is 3cm bigger then 225/55 R16 in diameter. my 225/60 R16 keeps touching the body even though i have replaced the front gas struts. will go for 225/55

gha - what size tires are you using on those 16" rims? i am running on 225/60 R16, and thinking of changing to 225/55 R16 for better handling and less touch between tire and body wheel arc

gha - what size tires are you using on those 16" rims? dont remember for sure but they are exactly the specs of OEM '93. will check it for you

my '90 ls400 is running '94 16" rim and the tires keep kissing the inner plastic wheel arc whenever the car bounce a bit hard not sure if its the coilover or struts or the bigger rim, but you may need think of it

well, i read the repair manual for A340E automatic tranny on 1UZFE. this is quite simple to achieve if you connect a voltmeter to terminal TT (+) and E1 (-) the volt changes will indicate gear position as in table below Gear position/ Terminal TT output voltage 1st gear/ below 0.5v 2nd gear/ 1.5-2.6v 3rd/ 3.5-4.6 O/D/ 5.5-6.9 with some skills on electronics, we can make the output human readable

what was your approx. average speed?

i read on some sites that 1st gen LS400 drinks only 9 and 12 liters/ 100km (city - highway) mine does it heavily with 22 liters /100km constantly so far in city and around 16l/100km highway given that average speed in city is about 20 mph and 40 mph for the so-called highway does the car has any problem or the milage is okay at that average speed? btw, my '90 ls400 just did nearly 90k miles. and i am running with check engine light on for oxygen sensor

in yr case, there would be no issue with the changer machanism since it can still scan the discs. have you cleaned the lense?

in this 4r, i dont know of any special but simly regular preventive maintenance makes the car last no idea about your question 2, as i think putting a turbo charger on it would not be a "relatively simple way". an electric turbo definitely wont work

glad to hear you are happy with your choice. whats about its milage compared to your previous 911 and series 5?

a good leson from this incident, always have a backup key safe somewhere you have access easily. My first mod for my car is to copy the key (try it on my car to make sure it can open the door) and then safely keep it in my house. by this way, i can be sure that i will always have an option if i lost or locked the key inside

i watched an engineer removing ps pump ('90 ls400), he didnt work from the bottom, he simply removed the drive belt and had full access to it, no need to remove the alternator. not sure if this is the recommended way, but it surely works

if you can remove the door panel then finding the problem is much easier. there are some areas you will need to look at 1- bad mass connection for the motor there is a button on driver's door that dis/enable window up/down of all doors. this button actually provide mass connection to the window motors. your car is there for many years and the mass may not as good as it has to be, so the motors do not have enough power to operate. to fix, find the mass wire to the motor and connect it directly to the door metal then try. if the glass goes up faster then .... bingo, you find the root cause. and i assume you will know how to fix 2- stiff window glass support mechanism this may cause by lack of lubricant, simple to fix 3- stiff window weatherstriping lubricate inner side of the weatherstrips with some candle wax would work fine. NEVER apply engine greese, oil to the weatherstrips or you will damage them 4- bad power window motors this does not likely happen to even cheap old cars, you may need to replace them the above causes are listed by possibility high to low, you may want to do from top down until you get the real cause a quick question, did you operate the window from driver's main switch? was it different if you use the switch and each door? hope this helps
