About a month ago, the key on my 1984 300SD got stuck in the off position. I did my homework and got it to turn THAT LAST time (after about an hour of trying.) So I removed the tumbler and proceeded to drive it by starting it with a screwdriver. Once home I procrastinated getting a new tumbler since I was able to start/stop the car with a screw driver. After a few days of this, I noticed the ignition was getting stuck again. I eventually figured out that I had to push a little latch inside in order to start the car. At that time, I concluded that the tumbler did the pushing for me when it is in place. So I hurried and got me a replacement (used) tumbler. (A buddy of mine has an identical car that he uses for parts.)
I used it for about 2 weeks without any problems and I was getting ready to order one from the dealer (since my buddy's was on loan) when I noticed the key was sticking again. Well, last week, it got stuck again. It took me about a week of trying (a few minutes here and there) to get it to turn THAT LAST time again. So now I have removed the tumbler again and am back to starting it with a screw driver. Actually most times I start it with a pair of needle nose pliers so as to not disturb the "latch" I referred to earlier.
At any rate, now I'm thinking the sticking is not due to a bad tumbler (both tumblers turn fine when outside) I'm starting to think I have some other issue going on. Perhaps the mechanism behind the tumbler is what is faulty. I've done more homework but I have yet to learn anything about this possibility.
Anybody here have any clues?
Anybody have detailed instructions on how to remove the cluster panel to get to the mechanism that starts the car. If I can take it apart maybe I can learn something.
