Certainly nothing I've done, though in the past, I have noticed the fan seems to activate almost instantly.

Don't know if you have this, but section 24 has the wiring diagrams and shows the wiring for the various components powered by fuse 12.

If everything is working with a new fuse, it wil be hard to troubleshoot until the fuse blows again!
Thank you for this. Pardon my inexperience, but as I have manual windows, you are referring simply to the Aux fan relay? Would unplugging the Aux fan be the same as removing the relay or is that too far downstream?

A five-pack of fuses just arrived from Amazon so I suppose I have about four shots at getting this right.
