Yep, def sounds like the connection melted (as they tend to do). It will keep killing fans and fuses until you fix it. I just cut the end off mine and did 3 female ends to connect to the fan.

Mine didn't look bad the first time, then when I checked after the second fan motor, it looked like this:

The fan is completely locked up and the blade won't spin by hand - can an electrical issue cause the motor to seize? Thanks!!!

Yes and No, though I will present scenarios in No/Yes order:

A moderately "burned/melted" connector would behave as a "highish" value resistance in series with the fan motor, limiting the amount of current it could draw and reducing its speed and power--basically the same thing the ballast resistor does to achieve the low fan speed.

engine cooling fan low speed ballast resistor (the smaller component below the wire-wound resistor is a thermal fuse):


That's the "no" part.



The "yes" part is that if the connector were badly burned up, and sufficiently resistive, the fan motor might no longer turn fast enough to cool itself. When that happens it would overheat, burn up the grease in its bearings and seize.

The thing about dirty corroded overly resistive connectors is that they themselves heat up and get worse--which makes them heat up, and get worse--which makes them heat up, and get worse; etc...

Low voltage, will burn a motor up like "quick". Lesson learned!
