YUP! Bentley definitely missed it there. I got a clue from the microfiche,
but it still took some further investigation ... I don't have a lot of time,
but let me give you the basics. The column lock mechanism slides off the
steering column. This means that the process involves removing the steering
wheel and the column switches (3 screws). You then need to remove the plas-
tic shroud around the exposed portion of the column (I found I had to remove
the lower dash panel and remove a bolt that attaches the column to the body
of the car. Then you need to remove a pressed-on ring on the steering col-
umn that holds the spring that pushes the steering wheel toward the driver.
At this point the spring will fly in your face and the column will slide into
the dash :), but you can now loosen the column lock mechanism. The mechanism
is held in place by a single bolt (with 6mm allen head). If you look at the
plastic column shroud before you disassemble everything you will see a hole
in the bottom at the location of this bolt (probably to allow for adjust-
ment). After the bolt is fully removed you should notice that the column
lock can slide back and forth somewhat on the column. I used a mallet on
the column to disengage the column from the lock and then the lock mechanism
simply slides right off. Once you have the lock mechanism off it is pretty
obvious how the ignition switch module is replaced. It is held in place by
a single screw. The only thing I found difficult during assembly was the
reinstallation of the locking ring that holds the spring that pushes the
column toward the driver. I used the steering wheel and the nut that hold
the wheel on as a press ...
... well, it looks like I must have had time after all! I hope this helps,
and feel free to let me know if you have any questions about my description.
