Newer cars run hot enough under the hood to cause belts, hoses and spark plug wires to break down more quickly than older cars, so yes, plug wires that are old may start to melt, especially if car runs hot or is used in hot climate. Wires should be changed every 3 to 5 years, or even more often in hot climates or high performance use. Use only OEM quality or better wires.

it is very common for the heater resistor to produce heat and create the problem you are stating. It is caused from poor connections and then in turn create more heat and melt connector. The fix is to replace the connector like your stating....BUT most important, make sure connections get soldiered. Also make note, when plugging in, make sure connection is fully seated. Check for any damage to matting pins, signs of black must be cleaned, using small piece of sand paper or small file. If you have, apply some dielectric grease to pins prior to installing, it also helps reduce heat and keeps out moisture.
hope this helps, good luck and feel free to ask and more questions but responding to this thread

SOURCE: I have a 1996 Honda Accord that ran hot, plug wire tips melted
it is really not good to run that hot, metal temper fails...
your description sounds like you will need to replace the wires, do it one at a time and that is the easiest way to not mix anything up..
After you get it going, measure how many quarts of oil you burn in how many miles, you may have killed the engine..

Testimonial: "I have tried to replace the wires but the tip of 2 of them has melted onto the plug, how do I get them out?"
SOURCE: 1994 honda civic; why would spark plugs wires melt
bad connections cause excess heat might test the coil(s)
SOURCE: my car is a 2001 kia rio it had overheated and
if it does not start while only turns, check if fuel comes out from pump ,also check ignition ,spark plugs good connection.
