ignition switch????
 

Hi everybody, I have this 1984 300sd with 218,000 miles on it. I went to go start it the other day and the switch is locked solid. I can get the key in and out easily but cannot turn it. Tried turning the steering wheel thinking the interlock was stuck but still no help. So im thinking the switch finally bit the dust. Can ya'll offer some advice on either replacing or fixing this problem. Thank you for any and all input. Eric

Thanks Forced, I have a new ignition switch in hand from mercedes and a new tumbler on order also...Damn thieft related items take 2 business days to arrive from Texas. So in the mean time I am going to try and remove the old one for know and wait for the new tumbler to arrive.

One question, Ive already broken a couple trim panels trying to remove them. So im asking for some expert advice on removing dash and bezel without damage. Any advice would be much appriciated!!!

UPDATE: ok well i was still not able to turn the key to remove the tumbler. So after talking with a local mercedes dealership, I now have a brand new steering lock and tumbler assembly. So my next question is, the harness that goes to the ignition switch? Does anybody have a diagram of this harness and where each of the wires is plugged into? When i pulled the old one out all of the wires came unplugged and I wasnt able to see where they mated to the switch:mad:!!!! So im looking for an accurate diagram of pin to wire locations. Thanks in advance for any help!!!!
