93 400SEL Potential Problems
So I just purchased a 1993 400SEL about 2 weeks ago. I keep hearing about these electrical problems that often occurs with these older models. My car is about 103k miles and is running great. I have not checked the wiring harness yet, as I don't want to mess around with an engine I am not familiar with just yet. But is there anything I can do to "prevent" the degrading of these wires? Or is my only option to replace the harness (if it hasn't been done already. And what other problems should I look out for? The only thing that has gone wrong so far is the driver side pneumatic door not working, but with a simple fuse reset, it works again. Thank you in advance for your patience and guidance with a newbie. Haha.
