Key cylinder won't turn off
Daughter called, her 93 sse won't turn off. I looked at it tonight, it seems either something is preventing the key from springing back, or a tumbler isn't engaged, or something is loose in the column. This happened to her last year, but couldn't duplicate it. Thought she was talking about the vats acting up, so I soldered in the resistor back then. No issues till today. The key is stuck in the on position, and can be turned to start with no issue, it springs back to on, but feels like it stops before it'* back all the way. Tried moving the tilt, shifter, brakes, t/*, but nothing seems to affect it. The brake / shift appears to be working properly. I suspect the key is badly worn as it is original with 160k and 17 yrs old now. I have a spare to test that theory if I could get the other out.
Btw, the safest / quickest way I've found to turn the car off was by opening the air filter box and plugging the air intake with my hand. Pulling the ground on the battery doesn't kill it.
I think I'm going to tear into it tomorrow night, starting at the column. Any tips or how to'* on changing a key lock cylinder in these? I've done one a long time ago, and it didn't turn out very nice. My FSM is in storage, but I can go dig it out if need be.
