>>>First of all, crescent wrenches and ignition keys don't mix.   That's 
how you wind up with a two-piece key. :<(

I have heard of difficulty going from the "OFF" position to the accessory 
position--that involves overcoming a cam inside the switch, and releasing the 
steering lock.   But once those hurdles are overcome, there is really 
nothing that should be preventing free and easy movement between the accessory 
and run positions????

What's especially odd is that you say movement back and forth between 
accessory and run is free and easy until you turn the key off.   Then the 
difficulty returns?   Are you sure the problem isn't going from off to accessory?   
That's the standard failure mode.

Assuming your description is accurate, it is certainly unique I think.   
For sure, your first step should be liberally spraying lock spray (available 
at any good auto parts or hardware store) in there (it makes a mess, be ready 
with paper towels) and working the switch back and forth.   If you still 
have difficulties, remove the electrical portion from the mechanical portion 
and see if it changes.   That's a simple bubble sort that will determine if 
the problem lies in the electrical portion, or the mechanical portion.   If 
it all works smoothly when the electrical bit is removed, then the problem 
lies there....

Let us know what you find out?

     anything, electrical switch vs. mechanical tumbler thing.
