Another fabulously helpful response that even my tired little brain can follow.
Thank you so much, again.

I got the fuse info from the paper glued to the underside of the fuse cover.
I would still wonder if it is normal that the aux fans are supposed to routinely come on, when I thought they would only come on in unusual circumstances of overheating.

It is raining like dickens here and I hope you won't desert me if it takes another 2 days for me to do what you suggested and then repost. It's just too messy working in the rain.
