My 1994 E420 (80,000 miles) is in need of a new wiring harness. After reading many post it seems that this is a major problem. Some people have been lucky and have had the dealer replace the harness under the "good-will" program. My dealer has no "good-will" left and MB Client Assistance laughted at me. Well, I am getting ready to battle MB over this problem and could use some help. If anyone has information that might help me I would be grateful. Any service bulletins, MB documents refering to the problem, etc., would be great. Thanks in advance!
