The ignition switch case kind of bugs me--how does the world's largest
automaker, with at that point nearly a century of corporate experience
in such matters, manage to screw up a damned _switch_?

Why does anybody put a pound of crap on the key ring besides the
ignition key and then complain if it has sufficient weight to cause the
key to change positions.

I've a vehicle that's on the recall list and I see no real difference in
the switch than any of the other GMs.

It is odd how that falls in place to cause a problem, unless the detents
in the switch it self prematurely wear out because of the rocking motion
of the keys on the lock.

The ignition lock turns more freely out of the steering column than when
mounted in the column. You feel more resistance when it is all
assembled properly.

On GM vehicles what you put the key in is the ignition "lock". On the
opposite end of the lock was a rack and pinion and rod. The gear on the
lock moved the rack and rod back and forth inside and along part of the
length of the steering column. The end of that rod connected to the
ignition switch. It may not actually be the part you see, the lock,
that is the problem.
