Have an A/C-equipped '89 Tempo/Topaz with an inoperative radiator fan.
I jumpered the fan to the battery, it works. I jumpered the relay on
the drivers side headlight, it clicks and my multimeter says it has
continuity when energized. I also tested the coolant temp sensor near
the thermostat and it has continuity when the engine is hot.
According to the Haynes, that leaves the cooling fan controller behind
the glove compartment. The book does not describe any testing
procedure, is this one of those replace-and-hope-that-was-it kind of
parts? The kind of auto repair that I hate?
Any advice is appreciated. Thanks!!
P.S. And why did Ford need such a complicated fan system, anyway? How
about a relay to kick in the fan when the A/C was on, the engine was
hot, or both? Seems to be a whole lot easier and cheaper to me!
