Car is a 1983 300SD. First time its been in to our shop. The owner was complaining of a battery drain problem. We narrowed it down to the power seats. The odd thing is as follows:
-Key off, door open, power seats SHOULD work, but they don't.
-Key off, door closed, power seats WORK.
No wonder that relay was hot when we pulled it!
For the life of me, I can't find the diode. It's not in the fuse box, as I expected.
Anyone who might shed some light on this?
P.S.---The car is an immaculate example, never been modified, one owner with under 70K original miles. Matter of fact, after 20+ years of ownership, the gentleman decided he no longer preferred the MB-Tex upholstery so he had all BRAND NEW leather seats installed at an MB dealer. I asked him if the problem cropped up after the seats were put in but he said it was present before.
