Its common for the plug to fail they sell a repair kit that will take care of it

there is a lot of current running through the wire when running, especially at start up

 

It was the resistor it's self that looked like it was starting too melt, on the inside of the pluggin. I was just wondering if its something that is common for the Durango to go threw, or is it the fan that caused it to melt. I bought a new blow motor resistor and replaced it already.

 

not uncommon to have the resistor fail; not uncommon to have the connector melt. The later resistors are a different design vs. the early resistors.

 

What year? My 2003 blows resistors like it needs the drug money. I have a feeling some antifreeze got into the cable bundle when the heater core leaked the first time and has caused me issues ever since, though it has been on decent behavior the past year. Typically every winter I'll go through 4-6 resistors and often keep a spare for when, not if, it goes.

 

Yes if they get wet at all they blow on my 2003 too. They need a new design for it period. I also keep a spare at all times.

 

Mines a 2003. I've since replaced the resistor and the wiring harness ( to the resistor) because that got fried as well, and it seemed too be fine, but once in awhile when I start the truck up when it's cold, the fan does want too work, but when I wiggle the wires it starts working. I've checked all the wires and they all seem too be good and tight. But I've notice the pluggin too the fan looks a little melted. The auto part store told me that it's the fan that's bad which causes the resistor to go out is this true or are they trying too sell me that to?

 

Hard to say from my experience. When my resistor fails it always works on full speed, just not on anything less than full speed. Do you notice this as well or do you get different symptoms?

 

when my '03 failed, it wouldn't run at any speed; there was a link inside the resistor that had failed (of course, it did this when I was driving home from Vermont, 35F and raining..) .. the original resistor was the older "card" style; the newer "ceramic" style may not have a blowable link for full speed..

pre-2000 (or maybe 2001) there was a relay that bypassed the resistor when running high speed.

When my resistor failed it wouldn't work on any speed. I'm just wondering if the auto part store is right or not when they told me that it's the blower motor that causes it to fail. Because it's shorting out. Can this be true or are they just trying too sell that to me as well?

 

I have the same problem with the 1 & 2 pins melting around the connector Its the motor pulling too many amps that does the melting. Needs a new motor. I changed out blower motor resistor and it the same problem eventually comes bacl
