Does the fan come on when you put the climate control into BILEV,
defrost, or AUTO?  If not, the fusable link has probably
melted/cracked/corroded.  The fusable link is a piece of metal that
melts when too much current is drawn by the fan; it's just a big
fuse, that's all.

It is directly connected off the fan via a large brown wire, and
housed in a small plastic box mounted on the side of the engine
compartment a few inches back from the fan; the cover may or may not
be still on the box; on many cars, the cover falls off.  Two phillips
head screws serve as terminals; loosen them and the fuse will come
off; looks like a thin strip of aluminum.  If you look back a week or
two, I posted the part number for the fuse; well under $5 from any
dealer, though some may not stock it.

When you remove the fuse, inspect it to make sure it didn't
melt(which would indicate a fan failure.)  If it looks like it simply
cracked or corroded, you're fine; this is a very common problem.

Avoid another boilover at all costs; it can cause some very expensive
problems like blown head gaskets and warped heads!
