Default 2000 LS400 problem with steering wheel adjust

We recently had our LS400 detailed and when we got it back the steering wheel was stuck in a low position. It will telescope in and out but won't go up or down It makes a "whistle" sound when you push up and no sound when you push down.

I tried a search and saw one post that stated a fix for this feature can run $2K Hopefully someone knows any easy fix. New to forum and thanks in advance for any advice on solving this issue.

Look at the "sticky" at the top of this LS400 forum for a link to the thread on fixing this issue - at least the fix works some of the time.

Yes, 2000 LS400's made later in the model year had revised tilt and telescope motors. I do not know if adding washers behind a sprocket or reversing a sprocket will work to fix the problem like it did on earlier LS400's.

My 2000 was built in June 2000 so I was lucky to get the revised parts installed at the factory ... haven't had any problems ... yet.

Here again is that TSIB dated May 19, 2000..

What about small electric motor rebuilding services? I bet they could put new brushes in those without much fuss. These little motors aren't too terribly scary once you open them up.... unlesss of course everything looks okay, then i guess it's time to replace!

The newer style motors do not have brushes; they are electronically commutated and are totally controlled by the electronics.

YoshiMan, there are no brushes in the new ones, they are magnet contacts (?) I took it apart but could not make it work....

my as pictured tilt motor is dead. I took it out slammed it on the ground 5 times and put it back in and it worked for about a week. Then stopped again.

Is there anything we can do to help stop these motors from failing?

And what kind of grease do they put on the shaft? It looks like mine could use some lube.

Mine failed with the column in the UP position.
Used vise grips to turn it and lower the column until it was where I like to drive it and haven't thought about it since.
Sux that these fail. I believe the programming to completely raise and then lower the wheel at every key insert wears the tilt motor unnecessarily.

Oh well.
