Yo Aemnky606,
Welcome!
If you have a tilt column, the ignition actuator rods are broken, preventing the cylinder from returning to the key-out position.
To replace, see ttps://www.supermotors.net/registry/media/573959
Or check with a local yard, some have local sources to replace it for you.
Also, accessories that fail to operate with the key in RUN, or that remain on when the key is turned off, may be the result of a misadjusted ignition switch rather than a malfunctioning ignition switch.
Test the ignition system mechanical operation by rotating the ignition key through all positions. The movement should feel smooth with no sticking or binding.
The ignition key should return from the START position back to the ON position without assistance (spring return). If sticking or binding is encountered, check for the following:
burrs on the ignition switch lock cylinder
binding ignition switch lock cylinder
shroud rubbing against ignition switch lock cylinder
burrs or foreign material around the rack-and-pinion actuator in the housing of the ignition switch lock cylinder
insufficient **** on actuator
binding ignition switch
actuator inside steering column is broken or ignition switch is loose.
The ignition switch can be adjusted by loosening the mounting screws, and sliding it up or down
