If you like to fix your BMW E36 electrical issues which normally happen very often and you don’t like to visit electricians almost all the time, then you must have the BMW E36 fuse box diagram. These diagrams can come in handy especially if your window regulator relay goes bad. The fuse box diagram is usually found under the cover of your fuse box, but unfortunately, it’s not always there. That happens because of two possible reasons. The first, is that it has fallen off and you didn’t notice it or maybe you got the car like this. The second reason is because you don’t have a fuse box cover 😆 (like me before I bought mine).

So, if you don’t have that fuse diagram then this post was made for you. I have found the fuse box layouts for both BMW E36 325i and the BMW E36 318is.

This is the 325i fuse box diagram:

And this is the relay diagram from the Bentley Manual:

And this is the 318is diagram:

I suggest that you either bookmark this article for later reference or at least print it and keep a copy of it inside your car and maybe stick it inside your fuse box cover. Have fun!

    I always find your blog very useful, informative and also very entertaining.
    This one is specially useful, because it reminds me what just happened to my e36 shortly I bought it.
    I bought a belgian originated left hand drive car in the UK, with no manual, no service book and nothing really, but it’s all fine.
    The reverse light gone off once, so I took it to a garage (this is my very first car in my life, and at that time didn’t really know anything about it). So when the engineer opened the fuse box, it turned out that everything is written in german, and noone really speaks german. So I had to dig up some of my primary school german knowledge from deep inside myself, which was particularly funny. After that I’ve decided to translate all the text inside the fusebox, but seemed to be quite a big job.
    Fortunately your blog just did it for me now. 🙂
    Thank you very much!

    […] So, I’m trying now to figure out how to re-connect my electric fan correctly to the auxiliary fan relay (which I found in the BMW E36 fuse box layout). […]

    So where are your relays for a/c and aux. fan (13-15). I’m having a heckuva time finding those same relays for a 1995 325i sedan. Would you happen to have part numbers or colors?

    Carlos, check the cover to your fuse box! You should have a fuse location diagram as well as Fuse # & amps.

    Hey I think fuse box diagram is the best option for the BMW E36 electrical issues and its easy to make also. thank you for valuable information. I liked it so much.

    I need the layout and color of the relays on a 1998 BMW Z3 roadster. High speed fan works, low speed doesn’t when wires for switch are shorted.

    the light of the battery goes on and off while driving. the car is a BMW 325i 1998. I also want to understand the role of eache cable that goes to the positive born of the battery. thank you very much!

  27. 27 On August 23rd, 2012, Anton said:

    Hello, would be great to see a pic underneath the fusebox/relay layout. And perhaps a electronic cable schedule.

    Hey guys plis help i have E36 318is motorsport international…my issue is wiper blades motor if i put the wipers on they carry on and stops anytime and once they’ve stopped the only way to make them work again is to switch off the engin and re start it. other than that i should keep trying to make them work and if they respond i cant control them to stop. what might be and issure here?

    I have a 1993 BMW 318i. Recently I blew three headlights at the same time. I replaced all bulbs (high and low beam) after this incident. The fuses were fine. When I turn them on they flicker as they had done in the past. I have checked the light switch and its okay. If anyone can provide me with a relay schematic for this model and year, it would be great. Any other ideas on this problem and a solution would be much appreciated.

  30. 30 On December 3rd, 2012, Richard said:

    Carl,check that the fuses are the correct amps. It sounds as if the lights wires are shorted some where, perhaps the headlight got some mist on the lights plugs.
