E39 (1997 - 2003)
The BMW 5-Series (E39 chassis) was introduced in the United States as a 1997 model year car and lasted until the 2004 when the E60 chassis was released. The United States saw several variations including the 525i, 528i, 530i and 540i. -- View the E39 Wiki

I found this, so, I would ask the OP whether it's accurate.
- Looking for the Horn Relay Location?

Today, a user troubleshooting weird electrical problems ran into this:

Did anyone else have the same problem? Thanks

2001 525iT...I have gone through this whole thread and I still can't figure out where my Auxiliary fan relay is. My box under the air intake has the salmon and the brown relay, but after reading it doesn't sound like either one is correct. My high speed function on my fan has quit. Low speed works, but at certain points the car is heating up at idle because the high speed is not kicking in while the AC is on.

It's there...I took the glove box out and then look up behind the metal plate that the fuse box is connected to above the big plug of wires, and with a light you will catch the glimpse of the two fuses. I had to use my monkey fingers and go over the top with the fuse box open to get them out and back in.

I just received this Fuse Housing from BMW and it appears to be incomplete. Is this the way they come through? BMW told me I would have to locate the connectors in the catalog... Say what?? Does anyone know a source of the connectors?

Given the water damage that car has experienced, I'd google for "marine grade wire crimp terminal connectors" for at least tin-plated copper terminal connectors.

I was looking to find the flat male comb type connectors to complete the box as original. I suppose I could just stack the connections on the posts. Might there be a reason this would not be recommended? Finding wire end connectors is not a problem.

It would appear that excessive levels of oxidation on the fuses and connections could be the effect of salt water or damp air, or simply a damp parking area.
If you neglect additional reinforcement in the midst of harsh conditions--even of those conditions are defined by a messy passenger or broken window, for example--the lifespan of the under-seat fuse box will be shortened significantly.
It is also important to note that automotive hardware is generally made to aviation specifications- not the regular stuff you pick up at the hardware store, hence @Bluebee's recommendation for you to prevent corrosion by strengthening up. If you are going to use anything less, it should only be a holdover. I arbitrarily define 1,000 miles as my duration anytime I have applied a temporary fix.

Thanks Allen.
I'm in the marine industry and work arounds are commonplace. I'm new to BMW OEM part procurement, so I have a learning curve as to what is considered a complete OEM part. Am I too assume it's common to receive equipment with missing parts and no available BMW reference to the missing parts? I understand upgrading components, but missing components in an OEM part with no available reference to complete the part seems odd. Given all the attention to VIN numbers, body specific parts and all the apparent documentation required to procure a specific part, I'm baffled by the seaming lack of information and feigned ignorance of some dealers. I realize it's up to me to establish a bond with a dealer or repair shop and my ignorance doesn't help to complete the circle of trust.

Solid brown should be ground and in almost all cases it is. Never hurts to check with a multimeter.

Um, the blurry picture and angle of the wires make it hard to see what color combinations you're dealing with, not to mention the absence of your car's birthday and model. Will gladly assist with such info

Yes there is sometimes difficulty with these things but dealer and OEM is best for electrical repair. Don't want to end up with more failed systems from OECHIN replacements like I did
Splice and solder is your next step it appears.

This fuse hint by cn90 today will be useful to those who come here to figure out what fuses to pull to prevent twisted seats:
> E39 (1997 - 2003) > Permanent solution for twisted seat problem?

- Adjust the seat and SW the way you want
- Then remove Fuse #13, just make a note that you did this so later on, if you need to adjust the seat and SW, re-insert Fuse #13.

I removed Fuse #13 4 years ago, and have not had the need to adjust the seat or SW during the last 4 years.

... when I spied this nice picture of the additional ebox fuses, added for a cooling fan, so I include them below, so it's all in the same spot for others to benefit from easily:

HEy Bluebee,

I see my engine bay fuse compartment looks a lot like yours. I see others on here are a lot different, even though same e39. Anyway, I noticed someone before I bought it was definitely in there. and made a mess. There are two relays that should be mounted, but are hanging free (broken plastic). There is also some sort of metal sensor on bottom right that you and I have but others don't. Almost like a water level sensor, or temp sensor (it's metal). My back right water proof rubber gasket by firewall that holds all the wires, wasn't even in right (hanging out), my EF1, etc. fuse section cover is missing, there are two wires oddly taped together (not sure if anything at all but will open up), and there is a cut or broken wire (yellow with blue stripe), that I cannot see anywhere where it would go. I was in there looking to see if anything would be a sign of my ABS issues, or intermittent check brake linings message (which brakes are new, and sensors changed several times, and reset a million times to no avail). Also, one screw holding cover to compartment pulled out the other end, and another one was completely broken off. Jeez.

Anyway, FYI posting for others to see what my fuse box looks like and also to ask if others have those two wires taped together, and more importantly, of others have a mysterious wire missing. I have had NO work done to my car in there since I bought it 2.5 years ago. My ABS and brake sensors both failed many many months apart from one another, and both worked for months after I bought the car. So any broken wires were already there.

Any feedback appreciated.

What did you end up doing on your fuse block, if it were me, I would disconnect all the fuses, and terminals, clean them and the posts with a fine brass wire wheel on a Dremel tool, or cordless drill, then reattach them, and protect it with a coat of Vaseline, or battery terminal protector spray. Soaking the terminals in a baking soda and water solution may also get the corrosion off at the crimp connector, I learned that in high school electronics.

For reference, there was an update to the thread today on the three locations of the fuel pump relay (K96) on the various E39s...

Blubee......

I've been wading through this thread but can't find what I needed (could be I just missed it!!). Do you know which fuse controls the trunk light in a 2012 535i (F10)? THANKS!!

BTW, your PM box is full......

You'll have more chance of an answer in the F10 forum. This is forum focused on the E39, designed about 20 years before the F10.
