I have a 1993 300SD with 255,000 miles on it.

I had a problem with one of the auxillary fans running all
the time.

Upon inspection, the dealer found that my wiring harness
had a bunch of cracks in it. I have the harness. For part
of it as least, there is a crack in the wires about every
1/8th inch.

So, if you have over 150,000 miles or so or are having
wiered electrical problems, you may want to have your
wiring harness checked.....just bring your wallet!
