Thanks for the help. My 2004 LS430 had the steering wheel stuck in the lowest position, and was not moving up or down. I had an estimate of $961 to fix this. They claimed the motor is bad and needed to change. I just didn't think I wanted to spend that much for the inconvenience of having it be too low.
I actually opened the casing around the steering wheel, found the shaft of the tilt motor. There was also an allen head screw or bolt, I just loosened it a bit, then with a needle nose pliers, twisted the shaft by hand and saw the steering wheel go up. I kept doing it, got it all the way up. Then a surprise, I turned the ignition on, and then the tilt started to work.
I tried a few times, it works, but I'm not pushing my luck, so it is just in the 95% up position, it is very comfortable. Thanks to all the contributors that gave me the idea of doing it.
