The rest of the endlessly repeated material  has been snipped

IIRC, there IS NO fuse for the fan, that's why we have melt downs, and 
why there's a pretty well known fix floating around in the archives.  
One fuses the ground for the fan.  Next, the fan switch is on the 
inboard side of the radiator, near the thermostat hose.  Unplug the wire 
and jumper 2 of the three connectors.  You might have to move the jumper 
around to find which ones.  One is an input, the others are the 2 speed 
outputs (one for high, the other for low).  If the fan comes on, the 
switch is likely bad.  They're a common failure point.  If it's bad, 
resist the urge to install a cooler switch.  You're fuel mileage will go 
away and the car will always run as if it were in the warmup mode.  
Might want to look at the condition of the connectors while you're 
there.  If it doesn't come on, yopu could have a power problem.  Check 
for power at the large post on the back of the fan motor.  Check the 
resistor block locared on the left frame rail.  When you've done these 
things, report back.
