This is most likely a failure of the fusible link; it is on the strut
tower right behind the fan.  Usually, the cover breaks off, the
terminals corrode, and the link eventually just snaps.

The break should be evident; if so, replace...any dealer should have
it for practically a dollar or two.  You can replace it with a
fusible link wire(instead of a blade) of the same rating, in a
pinch...which lots of places have.  A 60A wire should work too, I
think I remember people saying 80A was pretty high.

Part number is N 017 125 3, and I believe it is rated 80A.

To be safe, disconnect the battery before changing the fuse(just have
the security code for the radio handy.)  Technically if the after-run
circuit came on, you could cause some pretty fireworks with your
