The fuse for the auxiliary fan on a 1998 BMW 318i is typically located in the fuse box, which is found in the engine compartment. You can identify the specific fuse for the aux fan by referring to the diagram on the cover of the fuse box, usually marked with a symbol indicating cooling fan or auxiliary fan. If you're unable to locate it, consulting the owner's manual can provide additional guidance. Always ensure the vehicle is off before checking or replacing fuses.
I have similar problem with my 1990 318i and found that the aux fan not working (if you connect power directly - it works) because the thermal switch circuitry is faulty. I have then bipassed the thermal siwitches and made it so that the fan should run when ac is on. It worked for some time but then the fan being faulty itself is drawing too much current and blowing the fuse.
