    On my e36 the rear fog light fuse keeps melting. Its the right size fuse and it doesnt blow, not even once its melted. If there was a problem surely it would blow. By melting could it be a sign of overloading on that circuit even tho it just does the rear fog light which is hardly used

    I've come across this before on a few different cars and fuse types. it seems they draw enough current to get hot but not enough to get into the pre-arching and arching phases, so basically melt the fuse over time.

    I'm not saying it is good or ok just that I have seen it before.

    What fuse rating?

    If I was a betting man, I'd say check the boot lid loom. Sooo common on E36's.

    Even if the outer insulator looks ok, the wires underneath become brittle and crack. Leads to all sorts of electrical gremlins.

    BMW do a repair kit for it too - about £40 from a stealer.

    Or do it yourself with a soldering iron and electrical tape. Much cheaper and works just as well.

    I tried halford fuses and this kept happening so I got some BMW fuses and this stopped happening....not saying this is your problem but it could be the fuses you are using. If it was the bootlid loom then I would expect other electrical gremlins happening too

    When mine went, the only symptoms were a slight draw from the battery (which you'd only notice by it not starting after being left two weeks) and it kept blowing the left side light fuse.
