Yep, that was the key. The main relay is directly above it. Removing
the instrument surround didn't help at all. The cooling fan timer unit
is bolted on top of the main relay bracket and I couldn't figure out how
to remove it, so I pried the relay out of the plastic case, as suggested.
One of the solder joints had obvious damage from arcing.
I re-flowed the solder joints and reinstalled the relay, and the car runs
fine.
