During an inspection of my relay compartment I noticed that the spade 
connector to the fan circuit breaker had gotten so hot sometime in 
the past that it actually melted the black plastic surrounding the 
spade connector. Upon inspection I found that the spade connector fit 
so loosely on the circuit breaker that I surmised the voltage loss 
across this loose connection was responsible for the heat build up. I 
repaired the connector and all seems well. My general feeling is that 
there are many loose spade connectors like this in the car. High 
amperage connections would be especially prone to over heating. Best 
to check them all. Some can be tightened up with a pair of needle 
nose pliers. Others should just be replaced.
