Steering wheel movement should be smoothly transmitted to rack and pinion input shaft. Check steering column for binding and inspect two "universal" style couplings on steering column.

Thanks... I've seen my mechanic, I'm good for a rack & pinions change.

$450,00 all inc.

Ok, I'll try to explain that the best I can.

When I go straight ahead, my steering wheel is straight.

If I turn right, then go straight, my steering wheel is 15° tilted to the right.

If I make a left turn, then go straight ahead my steering wheel is normal again.

Alignment has been made, didn't fixed the problem.

When I turn the steering wheel there is no suspect sound (no "clongs" nor whatsoever).

If I go straight and release the steering wheel, the car doesn't move from its trajectory...

Question:

• Is there something to tight between the steering wheel and the rack and pinions?
  
• Is it a problem with rack and pinions?
  

Thank you in adevance for your help

I heard SilverStar 9006 ST were good but the lifetime is very limited!

Anybody got an idea or have already tested some good stuff?

Ted7, Download the Lexus_SC_300_400_Factory_Workshop_Manual, from the link below and type in seat memory in search function. It may help you find the problem?

Thx a lot for that great file!

Anyway, problem solved... in fact (ahem) I pulled out the door panel and found out the module was unplugged...

Works fine now (obviously), but thanks to all of you for the precious help provided!

Ted, Are you getting a signal beep, while pushing the "SET" button 1 or 2? You might want to take a look at page 78 in the owner's manual: Conditions for memorized position activation.

Nope, no beep, nothing, nada, rien, nieks!

So, what's wrong ???

My SC got alzheimer or what?

Yes, in the rubber. It is possible to pull it out of the car side and push it into the door. Just enough room to get a look once you peel off the electrical tape. If there is not enough room to work, you can:

A) cut a hole in the rubber; or

B) Take the door apart to gain access to the rubber from inside the door and pull it into the door for the most room that you need. (It's not that difficult. Just a bit more time.)

But before you do that, make sure; with door open, grab the wire bundle(rubber) and wiggle/twist/bend it while operating the window. If you can get it to stop you that's it. Maybe use an adjustable wrench for the grab, just don't go overboard on it.

I finally found some time to fix this thing! Cable was cutted inside the rubber, made a bridge, works again!

Since I hate A/C this is a big relief!

!Thx for the help! :)

Yup, on P, contact ON...

Where is the problem ? The 3 buttons module or something else ?

Almost a year later and still not working :D

Maybe some new member's got an idea? :whistles:

First off; if the cable was broke, it will not work! Second, where is the buzz coming from? Most importantly you say that when the door is open, it works. To me that sounds like the wires. Try looking for broken/frayed wires in the bundle in the door jam.

Yes sorry, I used the wrong term, I was speaking of the wires that may be frayed somewhere. The buzz is coming from the window panel control.

So you think I should open that rubber hose that goes from the door into the car?

Hello

I know the reason why it's not working, obviously the cable has broken somewhere near the door.

When I open the driver's door I can open both windows, when I close the door, no windows are moving (just hear a buzzzzzz).

The only thing is that I don't know where the broken cable is.

I'm sure I'm not the first who had this problem, so if anyone had the same issue here, I'd like to know where to investigate.

Thx in advance for any help

No, the lack of power is of course when I turn the A/C on...

JW bout that u did say when u turn it on or off.

Right, I was just a little bit tired when I wrote that post ;)

It could be anything. take a look at your serpentine belt for flexibility.

Will do, thx

You shouldn't feel a lag. You have the V8.

So, what could be the cause? Compressor ?

No, the lack of power is of course when I turn the A/C on...

Is it normal that I feel a serious lack of power when the AC is on or off? (SC400)

Got it, it was well hidden and retracted, thx for the tip, I feel better now with all the lights working...

OK, the wire snapped off from the main wire bundle. If you look to the right of the right trunk strut, you will see a black bundle of wires wrapped together in black "tape" running down the right side. The photo you have showing the wire dangling pulled away from that main wire bundle.

Peel apart the wire protector and look for the cut wire in the main wire bundle. I crawled into my trunk so that I didn't have to hurt my back. Hope this info helps. My SC400 was the same way. Once I spliced the wires back together, my third brake light was back in business. When you do get the wires spliced back together, consider rerouting the wires for a looser run so that it doesn't happen again, otherwise everytime you open and close the trunk the wires are pulling apart.

Thank you, I'll have a closer look at it this morning

Alright, I investigated why my goddamn third brake light wasn't working, and I found this !

Now does anybaody have any idea where is the rest of this cable ????

Where does it come from ???

Thx a lot for the answer(s)

:D thank you so much!!!! you were absolutely right !, 2 broken wires, I spent $10.00 on wire and crimp connectors and my neighbor fixed it PERFECT !! not even one LED was out, just like NEW again!!!! Thanks again, Lynn.

Where was it broken?

My third brake light or spoiler brake light does not work on my SC-400 (1992), ?....every other light on the car works ?? ANY HELP would be very thankful !! Lynn.

Got the same prob, need to change the leds (means taking the spoiler out)

Before the SC, I drove this for 5 years, every day of the week, sunny or rainy, cold (record: 10°F) or warm (record: 105°F)...

It has been the best investment ever I made

I drove it for 70.000 miles and sold it the price I bought it! (even a little bit more)

I recently acquired my first Lexus - a clean '95 SC400 with a bad climate control unit. I have mechanical and soldering skills but am a little uncertain how to remove the unit, and what a repair will consist of other than the obvious replacement of the LCD. The climate display in half black and none of the HVAC controls work; no fan, no A/C, etc. Will replacing the display restore operation, or is there more to it than that? I've checked all fuses, etc, and all are OK. Love the car, but dealer prices on parts scare me to death....$1184 quoted for a new climate control unit. Any help on secrets of removing the unit from the console, acquiring a new display, etc, etc, will be greatly appreciated.

Thanks for the quick reply and the information. I have mechanical and soldering skills and could definitely do the repair work but I have two questions:

1) Does the display being black prevent the climate control from functioning? None of the climates control do anything.

2) I've removed four screws to remove the console trim piece but can't locate the last two near the ashtray area.

Everything you need as instructions are here http://lextreme.com/tutorial/sc_installation_guide_v2_B.pdf

Coming from this page here http://www.lextreme.com/lcdtech.html

Check on ebay, I saw one complete set for sale actually.

Mine was all black too, I just order a new LCD and replaced it myself (first time of my life I was soldering something).

Works great now!

Anyway, a Lexus is not a track car!

Track cars are lights, that car is way too heavy!

One day on the track and you're good for changing your brakes and your tires, not to mention the gas you'll burn!

Ah, but the SC and IS's are. Both of them have raced on the JGTC and Australian Grand National Circuits for a couple of years. The SCs are heavy, true, but you can reduce the weight. That's what Modification is all about, making something that's good, better.

Ok, but here we are talking about full stock Lexuses going on a track-fun-day! Not a few cars can do that (I had one and it was certainly funnier than an SC)
