Great e36 headlight switch wiring diagram - I pulled the dimmer transfer and headlight switch and checked continuity within the wires, all was great. The headlight transfer had some small pieces rattling round internal, which changed into now not a great sign. The transfer continuities checked out, however i ordered a brand new switched besides. I disassembled the vintage transfer and discovered that 18 years of temperature cycles had became the plastic detent ring in the transfer into a thousand portions of brittle plastic. I still had hopes that the dimmer transfer turned into too blame and i had no manner of without delay testing it. While the new switches arrived, i changed them out. Nothing, the trouble become nevertheless there. The burnt out connector is for the high velocity fan relay. Through using the incorrect relay, the interlock that prevents the excessive velocity and occasional velocity winding from being grew to become on on the same time become defeated and the 30amp fuse forty one turned into fed immediately through the small gauge wiring feeding the relay manipulate. So it burned up. This has been my present day project considering that final august.? masses of electrical reconditioning, soon i can get to the driveline.? lawn variety cosmos black 95 m3.? first year of the greatest m3s made!.
For destiny hassle shooting and rationalization, here's a diagram that details what relays go wherein, and what the pin capabilities are (this appears to hold for each year of m3, and may preserve for all e36, ymmv, caveat emptor, don’t sue me etc. And so on.): The proper relays are. My cash changed into on the dimmer transfer because even earlier than the lighting fixtures failed i had to jimmy the dimmer to get the lighting to come up to complete brightness, it acted light a rheostat with a lifeless spot. Whilst you study the schematic for the device lighting fixtures (6300.00) you see they're fed from the headlight transfer into junction x196 to the dimmer switch into junction x1019 and out to all of the lights (gray/crimson wires). At the beginning i although i had an open circuit when you consider that i had no blown fuzes. Because each light went out on the same time that narrowed it down to 3 opportunities:.
In my case the previous proprietor reputedly didn’t get this and simply were given 3 cheap relays from pelican (bmw element # 61.36-1 391 397, those are gray) and fixed them in while he restored the ac system after casting off it for autox responsibility. He turned into two-thirds fortunate.
