Sticky ignition cause and explanation with pictures.




Top view of slide inside ignition housing. Tab at far left circled in pic sticks out from housing and locks steering wheel. Block in center of picture is what we remove in the mod. In this position the ignition is on the steering wheel lock is retracted into the housing and the slide rails go under the lock block.



Side view of slide in ignition on position as above


Here the slide is locked locking the steering wheel. Notice the slide is blocked by the lock block. Notice the silver marks worn into the slide circled in blue this is where the slide runs under the lock block. This is what happens when you have the stuck ignition. The block will not come up enough to allow the slide to run underneath it.


Here is the slide in the ignition "on" position with the slide riding under the lock block as it should allowing the steering wheel lock tab to retract into the housing.



Here are pictures of the slide inside the ignition housing. The tab on the left end is what sticks out of the housing and locks the steering wheel. When the ignition is turned on the slide moves right and the tab retracts into the housing. The block with the pin on the bottom that we remove in the mod is what is in the middle of the slide. The pin on the bottom keeps it from being to deep and blocking the slide when the ignition is turned on. With the ignition off the spring on the top of the block that we remove in the mod pushes the block down thus blocking the slide from retracting.
When worn the block wont ride high enough in the slide groove for the slide to go under it. The slide rails start to catch the underside of the block causing the hitch you feel when you start to have a problem until finally the block blocks the slide completely and jams the ignition.



I hope this may help some more.

Slide and housing


Slide in "ignition on" position with slide running under lock block


Slide in "ignition off" position with lock block blocking in the down position keeping slide from being able to retract into housing. In this position the steering wheel is locked and the key won't turn because the lock block wont come up enough thus locking the slide in place
