The electrical assembly on the back of the key switch is bad. In order to replace it, I have removed the lower panel, the steering wheel & steering column switch assembly, and the instrument panel assembly. The electrical assembly is secured to the back of the switch by two small screws. There is a aluminum crash bar surrounding the key switch. How do I access the retaining screws? There are no holes in which to put a screwdriver.

you need to remove the steering column lock assembly (the part the switch is in) by loosening the #30 tamper proof torx screw. you will probably need to remove the key cylinder to make extra room to slide it out. knowing where to make a hole to remove the key part is a talent and will take a long time to explain. if you need it explained, leave another post.
