SOLVED: Aux Fan power circuit issue

[PalmSpringsE534.6]

All,

Finally took the E53 to the dealership and got a very odd diagnosis of my aux fan issues. I know when I took it in that I had power on the red/blue fan wire that runs from fuse 61 to the fan harness. They claim there is not continuity on that wire now. So it would seem I will verify what they say (which is very odd) and if true I will replace the wire.

Does anyone know the route of that wire from the fuse box and over to the fan harness? If it's a messy one, I might just wire from the + terminal in the engine bay with a 50A inline fuse to the fan terminal and put this to bed for now.

I may put a new wiring harness on the rig when I send the engine out for a full rebuild in a year or two.

Anybody played with this that can give me some guidance?

SOLUTION:
Wire actually routes (on my build as if it's a 4.8IS) from fuse 61 to Fuse 107 (on top of the fuse box) then onward to the fan plug. The red blade fuse was fine but we showed no continuity to the fan plug. Upon the suggestion of our members (especially BDC101) I checked fuse 107 and it sure was blown. The dealership refused to open up the top of the box as they claimed there was no secondary fuse (as per the BMW electrical schematic for 4.6is...which is DEFINITELY wrong on my car and seems like a few more). They were wrong. I pulled the fuse block out, opened the top case, checked for voltage across the fuse and found none. I replaced the OEM 50A (all black fuse) with one that I could see through in the future and tested. Fan fired up and has been running for a day and a half.

I hope this helps others that may be in the same boat thinking they have to pull a new wire from the fuse block to their fan plug.
