Help. I am a pretty good home mechanic but my electrical diagnosing skills are non-existent beyond basics so i post hoping those of you with sharp minds and more experience than myself can help. My 300D seems to be having some electrical breakdown which is manifesting in more than one area. The low beams work intermitently, high beams and fogs are fine. Changed fuses and the fuse box appears to be in good condition. Replaced headlight bulbs(Hellas). Alternator light flickers on a couple of times the first time the car is driven for the day, then it does not come on during subsequent drives that day, but does it again the next morning. The wiring to the climate control blower motor gets hot if i run it higher then the first position. I don't know if any of them are related. Car is driven regularly and mechanically quite sound. I am thinking maybe (or maybe not) problem originated a while back. I had to replace the voltage regulator in the alternator because the diode on the old one was physically broken. Please offer up ideas or thoughts you may have regarding this problem which do not require a crusher. Thanks!!
