One of the things I'm going to check tomorrow is something I think is called
the "heater resistor" which I took to be a coiled bare wire inside the heater
vent box. I am not sure of its purpose, (other than to ignite mouse nests that
get set up in there). But I removed the heater motor and replaced it (since
the mouse had also eaten about a third of the fan) and I vacuumed in there. I'm
suspicious that I might have bent the wire coil enough to touch it to the
box. The only thing is that I have disconnected the green wire to the heater so
AFAIK that should not be the reason that it still blows the fuse.
I've checked that fuse holder you mentioned but it was intact. On my car, I
think it's on a purple wire so it shouldn't be part of the heater circuit, but
obviously I'm no authority. Maybe that's the heater resistor??? I will check
it again.
Thanks
