The above fix works if you have anything other than a 91. If you have a 91, do the above and then cut the red wire going to the high speed relay, and insert a fuse holder inline. I guess 15 or 20A would be about right.
1990 and older. Fan circuit is protected by fuse.
1991. No fuse in circuit, add one.

instead of adding the fuse holder i opted for a relay that had a fuse built in.
001-542-96-19 this relay is identical to original minus the color and fuse
