Ok, question for you guys. I have a 93 sc400, bunch of little ussues. But my alternator went outo. So I changed the alternator out. Now my rpm gauge doesn't work. It may start working tomorrow.  Does it have its own sensor or is it the cam sensors? We know it's not the distributor. Any help would be great and thank you in advance

MI need did the same thing. Check power....good. along side of the bulb socket  Is the ground wire. I pushed that wire up and bent over the side of the socket. And the bulb started working.

"I have a 1992 SC400 That I have had for over 5 yrs. Mileage is around

208,000. The Total Extent of my Repair issues consist of Hmmm....

Lets See... Well I Had To Replace the battery once... normal (loving)

Maintenance i.e. Brake Pads, Fluids, tires, Etc. And Absolutely NO other

Issues. Would Find it More Trustworthy on a Long trip than my Other

Vehicle. 2002 Grand Cherokee Limited.

Lexus is a GREAT vehicle! Strict Unwavering Loyalty...

Until this weekend...

Not Sure Exactly what happened... in a three day period, 1. The

Power Window Actuator went out in the Drivers window,

2. The Illumination went out on BOTH the Guage Levers on Dash. (Gas

and Temp} 3. The Tilt Steering Memory/adjustment suddenly started

making a LOUD noise if you attempt to lower it. It is STUCK in the all the

way UP and all the way OUT position.. (quite Umcomfortable to drive)

4. The "TRAC" light is suddenly ON all the time.

5. Just Noticed a NOTICEABLE Vibration in the steering. Upon

inspecting the condition of front tires, found them toi be in QUITE poor

condition. (15K Miles into 60K Tires.) Apparently Front End is suddenly out

of alignment.

Anyone have any knowledge of A cherished, Loved, WELL cared for Lexus

having a Hiccup??

More Importantly, Had the Window Actuator, replaced at the Dealership.

The Modules for the "TRAC" and Guage Leevrs are on Order. The

Alignment Will be in the Morning... But The part that has me puzzled is this.

The Service Director (great guy) Told me that he felt strongly that the

motor was fine in the Tilt mechanism. He says he has had several with

the same issue and that when they get into replacing one, they usually

always find that it is only that the Bold / fasterer has back out enuff

to allow the gears to not mesh properly. He said that it was most

likely something that i could repair myself, and that the cost of having it

done at the dealership was QUITE Offensive.

Hence, I can fine NO information, Schematics, Manual for how one would

go about getting TO the module. Whats it look like, etc. I have

started it once and realized quickly that there must be a way that i was just

Not comprehending. I am somewhat mechanically inclined. Change my own

pads, belts, etc...

Any Info about How to recognize the Module... What all needs to be

removed Cosmetically? Anyone else attempted this??"

With the steering wheel up and down and being stuck in the up position. I took the plastic covers off the collum. On the bottom side youll see a motor. I took the plate off, 3 bolts. I think 8 mm. Removed the cover and could see the gear. The gear was falling behind the drive gear. I removed the the gear and placed a washer behind the gear. Put back together and has worked fine since. Now the in and out I haven't fooled with.

Hello all. This Scott. I have a 1992  and a 1993 lexus sc400. Wouldn't change for anything. Maybe just a little newer. The 92 was given to me and I drove it for a few years. And fell in love with lexus. Just bought the 93. Having problems passing emissions. But it's all good. I'll get it.

DEEP WOODS OFF. or any bug spray with DEET in it. Polishes it up like a charm Old headlights will look like new

I use this trick on all my cars. Best and cheapest thing on the market 

My 1992 sc400 threw codes not to long ago. 1 being throttle position sensor. Idle was all over the place. I replaced it and it's still doing the same. Code 24 is intake air temp. Sensor. This is where I'm lost. Is this apart of the mass air flow?
