The ignition key and lock is in the top of the column, the electrical part of the ignition switch is mounted further down the column. There is a sliding piece of linkage with rack type gears on it that connects the two. This linkage is made of pot metal and breaks often. The symptom is that is can push the ignition switch on but cannot pull it back to turn it off. If you get under the dash you can see the actual switch and should be able to manually pull the linkage back to shut it off. Replacing the broken part requires disassembling a lot of the column so it/s not an easy job. You have to get the part from the dealer.
I thinks it# 52 in the picture.
