Car and Driver LS 400 Feature, Dec 2017
Exhaustgases replied to CELSI0R's topic in 90 - 00 Lexus LS400
A museum car that has no options? That makes no sense. -
What is posted makes no sense. If it truly engaged in all gears then it would be going or moving in them all. You need to check for codes, and I think you meant all selector positions work while the car is sitting.

I discovered that the Idle air control motor bearings go bad and start to seize up and that causes all sorts of problems with idle and such.

Absolutely DO NOT CLEAN THE AIR METER. You will ruin it. $700. for a new one if you can find it.

Since yours is a 96 with OBD2 then yeah it would work.

Sorry didn't notice the year before. Any transmission shop will not spend the time to trouble shoot the problem, well maybe one out of 100 or so would, most of them just immediately sell an overhaul or rebuild, it makes more money than just a quick fix does. And some sneaky ones will sell the rebuild and just do the quick fix. Its difficult to find honest anything automotive fix it places. So its worth trying to change the fluid and at the same time check the solenoids, use a new screen and put the correct amount of fluid in. I'd check continuity of the solenoids and they could be quick triggered with power and also the wires as well as the selector switch should be checked.

Or idle control motor bearings seizing up.

And in a year or so when you have transmission trouble, it will be from that fluid that was used.

'91 LS400 Air Cond. Pressure relief valve
Exhaustgases replied to cutlass275's topic in 90 - 00 Lexus LS400
Wow a nice way to over charge for a cheap part. Even the whole base plate should not tip the scales more than $50. Please keep this updated if you find the part cheaper some place. I have a question so if that relief valve pops off does it just release the refrigerant? I don't think the pressure should go higher than 150 psi -
Something else that degrades and has a recommended replace interval is the O2 sensors. And if you go to the clublexus site there is a good bit of info on the idle air control motor bearings that can cause some major drivability problems.
-
What year car? And if the transmission was serviced along time ago and the wrong fluid was used now its showing up the not using the correct fluid. There is no one size fits all automatic transmission fluid when it comes to Lexus and Mercedes Benz. Its just not worth the experiment to use the wrong stuff.

Likely they are no longer available.

And most important what year of LS400?

wipers have stoppe working '92 LS400
Exhaustgases replied to jerryparks's topic in 90 - 00 Lexus LS400
So then the explanation was not very accurate then. And not electrical in nature, you should have said the wiper motor was running but the wiper on the diverside was not moving. Glad you got it sorted out. And for others asking for help, remember with out accurate descriptions of the problems us people trying to help can only guess. We do not see or hear the problems. -

Exhaustgases replied to jerryparks's topic in 90 - 00 Lexus LS400
Check for power at the motor, when the switch is turned on. I don't remember if there is a relay for it and its own little ecu these cars seem to have lots of them. -
If you sprayed stuff in the thingy after removing the airfilter you then ruined the air meter. New ones if you can find them are $700. never ever spray anything in that hole behind the airfilter.
-
The mechanicals is the easy stuff, if the body is ruined at all it makes fixing it a worthless money pit. If the body is perfect no dents and original perfect paint job then its worth fixing it. If the under side is messed up real bad kinda not worth the fixing either. Engines, transmissions, rear ends all wrecking yard items. And in the correct yard you could find them all for under meaning engine trans, rear end all together for under 1000. or just buy a 500 parts car and you got even more parts.

Since there are no schematics who knows. It is like something is connected wrong for that light.

Messing with the Air suspension. :)
Exhaustgases replied to The Wrench's topic in 90 - 00 Lexus LS400
With that as the problem the pump would work, the sensor just reads the wrong height. With more info I think we could have figured out the sensor deal, it is electrical but also a mechanical problem. -
For Sale 1993 LS 400 49,060 Original Miles
Exhaustgases replied to TheSilverTip's topic in 90 - 00 Lexus LS400
Billy I have to disagree. The lower the miles the better. Old cars are old cars, yes a very low mileage car may need some work. But as long as it spent its life inside, it can't be beat for paint and interior condition. The things it will need compared to a high miles car is nothing, even if the low mile car needs every engine and transmission seal replaced, so would the high miles car plus so much more. I would much rather an old car with 3 miles on it than the same thing with 250K or more. There is just way more value to it especially when it becomes collectable the beat and road tattered high miles job loses the value with all the road grime and salt and what ever else has banged the bottom or top and started a corrosion spot here or there. -
Also check tps.

Exhaustgases replied to The Wrench's topic in 90 - 00 Lexus LS400
Grounds and electrical connections. And depends for sure what is happening. Any noise from the pump? It could be the ECU for the system as well, I'm sure if its like gen 1's its in the trunk and getting moist or hot depending on your climate. Need info like what is happening or not. -

Exhaustgases replied to TheSilverTip's topic in 90 - 00 Lexus LS400
Need pictures, need to know what kind of options, what color, is the body and paint pristine etc. An old car, or for that matter any car will depend on what someone will pay for it. The smart thing would have been to not drive it and keep the ultra low miles it had. Even so its still nice low miles and that's a good thing. I'd guess at about 8K to start. -
Timing Belt Replacement, Did You Do Your Own?
Exhaustgases replied to 93ls400walt's topic in 90 - 00 Lexus LS400
For a non mechanic type the T belt is not a good diy deal. And can end up costing way more than having it done. -
In hot climate yes.
