I've followed most threads/problems in the forums for auxiliary electric
fan problems, but haven't seen my particular situation addressed, so....

1. My fan works. It runs at temps above (dash gauge) 100C.
2. But, when I turn the key off, the fan stops, even though
the engine is still very hot. (And the A/C, lights, everything
is OFF.)

We had a little Ford car years ago; the fan would stay on until
the engine cooled, regardless of the column switch position.

What is the logic for the fan to come on? Low and high speeds,
temps, A/C. A/C temp, etc.

Where can I get a real schematic on the 300E?

Thanks!
