Guys - I got a new key switch for the column, but the trouble seems to be deeper than just a bad switch.
I believe I'm holding part number 3E723 that rolls when the key is turned. Something is supposed to be in the "eye" of this part, to move the rod that activates the electrics, lower on the column. When I couldn't get the new switch to seat, it was time to dig deeper and remove the three screws that hold that collar on the column. The part was loose in there. The pic below, I have put it where it sits in operation.
Something has busted off. Anyone else ever face this?
I have a shop manual on CD which is frustrating. Wish I'd bought the paper manual. :-(
