Ignition switch repair
So about a week ago I go out to leave for work. Stick my key in the ignition lock and it turns with no resistance, no clicks, and no lights coming on in the dash. "Crap" I say. Lock assembly fubar. Take the wifes car to work and pick up a new lock on the way home. Take the old lock out, hmmm, gee it seems okay but what ever. Install new lock, same problem. Damn! Okay then, must be the switch itself. Okay where it that thing? (Remember when the ignition switch was right on the end of the key lock?) So strip the column down, find the switch, unscrew it from the column and lo and behold it works fine. Operate it by hand and the truck starts just as reliably as it always does.
So to get to the point-- there appears (obviously) to be some kind of linkage between the key lock and the switch internal to the upper column that is fubar. I haven't been able to find an exploded view and my cheesy Chilton manual only addresses lock and switch replacement.
Has anyone had to perform this repair?
