Question about 1995 Lexus Sc 400
I have just had the ECM preplaced and now the tilt will not go down, it acts like it is stuck in the up position. The motor however will run for about 3-5 seconds and quit. The telescoping side will still go in and out.
Open the gear motor on the left hand side of the telelscopic assembly. Take the plate off held by 4 philips screws. Using a 10mm socket, remove the bolt holding the platic gear. Remove plastic gear and insert the reverse way. Over the years, one side of the gears get worn out.

This is a simple mechanical issue (no electronics involved).
Remove the plastic housing from around the steering column and ignition area. It is held with screws from under the column area. There are two screws from the top that you may need a short screwdriver to reach. Some are phillips and some are hex head. Just take your time it will come.
Once open you will see interlocking teeth or "gears" on the top of the column. One in mounted to the column the other engages into the tilt release teeth. This is the tilt mechanism. The top lever is lifted up by the adjusting lever. When the teeth are disengaged the wheel can be moved up and down.
Look to see the linkage is intact from the lever to the top gear. Pull the adjusting lever to see it is working and trying to lift the top gear up.
It can stick. Use WD40 if struck. Try shaking the steering wheel up and down while operating the adjusting lever (right side of column behind the turn signal lever).
Still struck? Use a screwdriver to lift the gears apart. The wheel will tilt easily now. Move to the desired position and engage the gears again. It will now be locked in the position you want.
It sounds complex but it is not. Just take your time and it will be obvious.
Note that while working you should have the negative cable removed from the battery. You do not want to trigger the air bag or damage the electronics. With the negative cable removed you will not have a problem.
