> my electrical compartment - my fan fail jumper was melting and it was > super-hot. i unplugged it thinking it could start a fire, then drove 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.
